I’m ready to bring a full-featured medical tourism platform to life and need an experienced team or individual who can take the idea from concept to launch. The core goal is to let prospective patients discover qualified healthcare providers abroad, understand treatment options, and complete every step—from inquiry to confirmed appointment and travel logistics—inside a single, secure environment. Here’s what I expect: • A modern, responsive web application with intuitive patient and provider flows. • A secure backend that can scale as traffic grows, built on a technology stack you’re comfortable supporting long-term. • Essential modules such as provider profiles, treatment listings, real-time availability, booking management, payment p...
I am rolling out a new Identity Governance initiative and need an engineer who can take full ownership of the solution design and deployment. The core of the engagement is Identity Governance—specifically rock-solid Role Management, airtight Compliance and Audit reporting, and automated User Lifecycle Management. My environment is hybrid, so you will be connecting on-premises directories and systems with our cloud workloads. Expect to work with common IAM stacks (SailPoint, Saviynt, Azure AD, Okta, or similar) and the usual supporting tech—PowerShell, REST APIs, and modern authentication protocols (SAML, OAuth2/OIDC). What I need from you: • Assess the current hybrid identity landscape and document gaps. • Design an end-to-end governance model covering roles, acce...
I am launching an online “rental boyfriend” service and need both a responsive website and companion iOS/Android app built from the ground up. The core of the product is a smooth booking system that allows customers to reserve time slots with their chosen companion and automatically sends booking reminders (push, email, or SMS—whatever is easiest to wire up). Here is what I have in mind: • Cross-platform build – a single code-base approach such as Flutter or React Native is welcome, so long as the end result is a fast website and native-feeling mobile apps published to the stores. • Clean UX – browsing available companions, selecting a date/time, and checking out should happen in just a few taps. • Booking engine – real-time availabi...
I need a developer who can take this accounting workflow out of spreadsheets and into the cloud. The core of the job is to deliver a web-based platform hosted on Firebase, with data stored and transmitted securely. What the application must do • Let me spin up unlimited “companies” so each business keeps its records completely separate. • Provide simple Email-and-Password authentication for every user role. (If you think we should layer OAuth or 2FA later, keep the codebase ready for it.) • Offer a clean UI where I can create customers, assign them to groups, and then post two entry types—Payment or Journal Voucher. • For each entry I’ll input debit, credit and a narration; the system automatically stamps the exact date-time and shows ...
I’m ready to connect my Lovable account with GoHighLevel but need an expert to handle the technical details from end to end. The main outcome I’m after is a secure, fully-functioning integration that issues Encryption keys for public use so outside services or landing pages can tap into GHL without exposing any sensitive data. Here’s the flow I have in mind. Once the two platforms talk to each other, the system should automatically generate and surface a public-facing key pair while keeping the private component locked away. Although my immediate priority is getting those Encryption keys live, I’m open to expanding the build later to include contact management, automated email sequences, or sales-funnel tracking once the core connection is stable. You’ll hav...
Project: Premium Loan / Fintech Android App + Admin Panel I need an experienced developer or development team to build a smooth, premium and modern Android fintech/loan application with an original design and professional user experience. My current budget is approximately ₹2,00,000, so I need the developer to propose the best realistic MVP within this budget. Please clearly mention which features are included now and which advanced features can be added later. Customer Android App Requirements Premium modern UI/UX Mobile number registration and OTP login Customer profile Personal and basic financial information forms Loan application form Loan amount selection Loan tenure selection Loan application status tracking Customer dashboard Active loan details Repayment schedule Payment history/s...
I’m ready to move forward with a new web application and the very first milestone is a rock-solid user authentication flow. From account creation and email confirmation to secure session management and password recovery, I need the full sign-up / log-in experience built with current security best practices (hashed passwords, rate-limiting, CSRF protection, etc.). The remaining screens will be simple placeholders for now, so you can focus on the auth stack, clean code structure, and a deployment-ready setup. I’m comfortable with popular frameworks such as React + Node/Express, , Django, or Laravel, but I’m open to your recommendations if they speed up delivery and keep the codebase maintainable. Deliverables • Source code in a public or private Git repo • Sho...
I am looking for an experienced developer or development team to help build a vehicle transport load board and transportation marketplace, starting with the Canadian car-hauling industry. The concept, business model, workflow, core features and initial visual prototype are already defined, and we are now ready to move into MVP development. Unlike traditional bidding platforms, our model is based on fixed-price loads: a dealer posts a vehicle or load at a set price, a carrier can accept it instantly, and the assigned driver manages pickup, VIN verification, vehicle inspection, photos, signatures, GPS tracking, delivery inspection and eBOL through the platform. We want to build iOS, Android and web/admin together on one shared backend, with one mobile app that provides different interfaces f...
I’m building an industry-specific job portal dedicated to healthcare careers and need a full-featured recruitment marketplace from the ground up. The site will let hospitals, clinics and allied-health organisations open employer profiles, post vacancies and manage applicants, while professionals can set up a personal account, upload their résumé and browse openings through a robust set of search filters. Core features I must have from day one: • Secure résumé upload and storage, ideally in PDF/Doc with automated parsing. • Granular job search filters (role, speciality, location, shift, experience level and more). • Public-facing employer profiles that showcase company details and active listings, plus an internal dashboard for posting...
I need an experienced DevOps professional (5 + years) to build out our entire on-premises infrastructure. The environment will revolve around Docker containers orchestrated with Kubernetes, with configuration management and repeatable provisioning handled through Ansible. Here’s what I expect to be in place when we finish: • End-to-end CI/CD pipeline that automatically builds, tests, and deploys our applications to the on-prem cluster. • Centralised monitoring and logging stack that gives us real-time metrics, alerting, and searchable logs for every service and node. • A security and compliance baseline baked into the cluster and pipeline: secrets management, role-based access, image-scanning, and audit trails. I’ll provide server access, networking detail...
I need a straightforward mobile app called “QR Image Reader” that lets a user pick any existing JPG, JPEG or PNG from their device gallery and instantly decode every QR code hidden in that picture—no camera involved at any point. Here’s the exact flow I expect: • Home screen shows one large button, “SELECT QR IMAGE”, in a bright, colourful style that remains clean and uncluttered. • Tapping that button launches the native photo picker on both Android and iOS. • The chosen image is passed straight to a proper static-image QR decoding library (ZXing, ML Kit Barcode Scanning or an equivalent you propose). The app must handle different resolutions, orientations and multiple codes in the same shot without asking the user to crop. &bul...
I need a production-ready Android finance application that will easily clear a formal security review. I will hand over the compliance matrix, API partner documentation, and branding assets; your job is to transform them into a polished, secure app that covers: • On-boarding with KYC checks and biometric login (fingerprint / face). • Encryption at rest and end-to-end TLS in transit. • Account dashboard showing real-time balance updates with a detailed breakdown of holdings. • Searchable transaction history pulled via partner APIs. • Full audit trail—every critical user action logged immutably for future audits. The build must follow modern Android best practices (Kotlin preferred, Jetpack, MVVM, OWASP Mobile Top 10 mitigation) and ship with reproduc...

I need an experienced full-stack engineer who can give special attention to the backend of my platform and raise its security posture across the board. The frontend is in decent shape, but the core services, data layer, and deployment pipeline all need a careful redesign so that every request, record, and secret is handled with industry-grade protection. Here is the outcome I’m after: • A fresh backend architecture that scales cleanly and is resilient against common threat vectors. • End-to-end authentication and authorization flows, encrypted at rest and in transit. • Well-structured APIs with input validation, rate limiting, detailed logging, and automated tests. • Infrastructure-as-code or container scripts so I can spin up identical, hardened environme...
I need a complete payment gateway that can process Credit/Debit cards, Cryptocurrency, and Bank transfers seamlessly across Web, Mobile, and in-store POS environments. Robust security is non-negotiable, so the build must include Two-factor authentication, end-to-end Encryption, and smart Fraud detection baked into every transaction flow. To keep the scope crystal-clear, here’s what I must walk away with: • A scalable back-end capable of handling the three payment methods above • Front-end or SDK components that drop into web apps, native mobile apps, and common POS terminals • Security layer implementing the three features named earlier, with compliance reporting enabled • Clean API documentation and a minimal admin dashboard so I can track transactions and...
I’m ready to move my existing mobile app to the next stage by introducing two key capabilities: secure email-and-password sign-up/login and a fully functioning in-app purchase flow. The current build is stable but still lacks these revenue-driving and user-management features, so I’d like to fold them in without disrupting what already works. Scope • Implement robust user authentication based strictly on email and password, complete with validation, forgotten-password flow, and token-based session handling. • Integrate in-app purchases (consumables and/or subscriptions, depending on what the store guidelines permit) so that purchases are processed, verified, and recorded on the backend. • Refactor or patch any surrounding code that these features touch to ...
The goal is to create an intelligent Web Application Firewall that sits in front of my custom web applications, inspects traffic in real time, and automatically reacts to threats. The platform must excel at three core functions I have prioritised: Real-Time Threat Detection, Defensive Blocking, and Attack Analytics. Key attack surfaces to guard against are SQL Injection, Cross-Site Scripting (XSS), and Distributed Denial of Service (DDoS). Every request should be scored, logged, and, when required, blocked or rate-limited instantly. I want to see exactly what is happening through a live security dashboard and to manage rules through a clean API that my apps can call programmatically. Integration needs to be seamless: the WAF will be deployed in front of several custom web services, s...
My Hetzner-hosted Linux server has locked me out of the root account. I still have full access to the Hetzner Rescue System and the console panel, but the root password itself is unknown. Your task is straightforward: bring root access back without touching any user data or service configuration. I’m comfortable granting Rescue System credentials or temporary console access so you can reboot, mount the filesystem, chroot, and update /etc/shadow—or whatever proven method you prefer. Please document each command you run so I can repeat the procedure in future emergencies. Deliverables • Root login via SSH or console confirmed working • Step-by-step notes (command history and short explanations) • No data loss or service disruption during the process ...
