Backend & Web App Developer Needed – Operational Automotive Workshop App (MVP)

@Microlent

I noticed you emphasized VIN-based history, mandatory “after” photos, and zero tolerance for data loss — that tells me reliability matters more than UI polish, which is the right call for a daily workshop system. I’d structure the backend as a clean, backend-driven system using Node.js (NestJS) with a strict domain model: Users, Vehicles (VIN-centric), Repair Orders, Work Types, Photos, and Activity Logs. Every action is transactional, timestamped, and tied to a user to ensure auditability. VIN uniqueness is enforced at DB level, so history lookup is deterministic and safe. Photo uploads are stored with metadata (user, RO, before/after flag, timestamp), and business rules like “After photo required to close RO” live in the backend, not the UI. I’ve built similar operational systems used daily in logistics, inspection, and automotive contexts; including vehicle repair quoting (DentCraft-style), field tracking, and inspection platforms where photos, timestamps, and historical records are non-negotiable. Those systems ran on VPS deployments with SQL, full data ownership, and zero managed backends. Estimated timeline: 6–7 weeks for a production-ready MVP Estimated cost: USD 4,000–9,500 (fixed, based on final scope confirmation) I’m fully comfortable deploying on your VPS with MySQL/PostgreSQL and respecting strict IP and infrastructure rules. If shortlisted, I can walk you through the backend flow before any code is written. Best regards, Jenifer

Hi, I'm a full-stack developer who's been building operational systems for about 8 years. Your automotive workshop tracker really resonates with me because I built something similar for a fleet maintenance company - they needed VIN tracking, job history, and photo documentation for insurance claims. I saw your tech stack requirements and I'm completely aligned. I work with Node.js and Express daily, use PostgreSQL for anything that needs solid data integrity, and I'm used to deploying on client-owned VPS infrastructure. No Firebase or managed backends - I get it, you need full control over your data. The VIN duplicate detection is straightforward with a unique constraint and a lookup before job creation. For the photo workflow, I'd store metadata in the database and files on the VPS with proper naming conventions tied to the RO. The mandatory after photo to close a job is just a validation check before status updates. One thing I've learned from operational systems is that timestamps and audit trails matter way more than flashy UI. I'd make sure every action logs who did it and when, so if something goes wrong you can trace it back I'm estimating 4-5 weeks for the MVP at around $3,200-$3,800. That includes backend API, React frontend, deployment on your VPS, and basic testing with real VIN scenarios. Looking forward to discussing further. Talk soon, Kamran.

I’m eager to collaborate closely with you to ensure the architecture aligns perfectly with your vision. My estimated timeline for the MVP is 6-8 weeks. What specific reporting features would you like to have in the admin panel? Thanks,

@kishanbwts

I would design the backend using Node.js with NestJS for modularity and maintainability, paired with PostgreSQL for reliable relational data management. The API would handle user authentication, VIN workflows, and repair order CRUD operations, ensuring strict data validation and integrity to avoid data loss. Each action would be timestamped with user metadata, stored in normalized tables for historical tracking. Photo uploads would be managed via secure endpoints, linking “before” and mandatory “after” images to repair orders. I’ve built operational web apps with Node.js and React before, managing real data with SQL databases on VPS environments. I’m comfortable following your architecture guidelines, using environment variables, and maintaining clean, documented code in GitHub repositories you own. I estimate delivering the MVP in 5–6 weeks, including testing of all core features and deployment setup on your VPS. Cost: $3500 Could you share if there are preferred authentication libraries or standards you want to use? Also, do you have existing designs for the UI, or should I proceed with basic layouts for functionality first?

@Eliteinno

Hi there. Operational workshop systems fail when backend logic is loose and data integrity is treated lightly which leads to lost jobs photos or history. We solve this by delivering a clean Node backend with strict SQL schemas VIN first workflows and audited actions so your MVP runs reliably every day on your VPS. Before we proceed here are our questions. Which backend do you prefer Express NestJS or Fastify? What is your target MVP timeline in weeks? We have delivered this type of operational system before including job tracking photo based workflows and role based access using Node React and PostgreSQL on client owned VPS. Backend structure would be modular services for auth VIN vehicles repair orders media and activity logs with transactions migrations and environment configs. Feel free to check our portfolio or I can send specific samples in chat and as a company policy we also provide 30 days of post delivery support to ensure everything runs smoothly. Let’s discuss your project today!

@rafaelunag

Hi, Estimated MVP timeline: 4–6 weeks Estimated cost: €2,500–€3,000 I understand you’re building a real, backend-driven operational system for daily use in automotive workshops — VIN-based workflows, repair orders, photo documentation, and strict data integrity, not a demo. I would structure the backend with Node.js (NestJS or Express), a clear service/controller layer, SQL (PostgreSQL/MySQL) with proper relations (vehicles, ROs, photos, users, activity logs), and enforce validation + audit metadata at every step. You need me on this project because I’ve built production MVPs with separate frontend/backend, SQL-first data models, role-based auth, file uploads, and VPS deployments where reliability and data persistence were critical. I’m comfortable working inside a predefined architecture and delivering clean, documented code you fully own. A couple of questions to align quickly: • Do you expect photo storage on the VPS filesystem or an S3-compatible object storage? • Is the MVP single-workshop or multi-workshop from day one? Looking forward to building something solid and long-term with you. Best regards, Rafael
