Hello, I’m Muhammad Awais, a UK-based Flutter developer with strong iOS and Android experience and a track record in proptech projects. I will execute Property Stalker v7.6 by strictly following your spec, runbook, and the Codex prompts. With the complete UI designs, PropertyData and Mapbox APIs, and your developer handbook, Codex will draft code that I validate, test, and integrate into Bitbucket, ensuring proper dependency checks and deliverables mapped to each packet. The plan delivers a robust mobile-first app in 4–6 weeks, with clear documentation and a smooth handover for v2/v3 expansion (sustainability uplift, finance integration, and AI-assisted analytics). I’m comfortable with UK-based in-person meetings ~every 2.5 weeks (London/South East) and remote work in between, and I’m keen on a longer engagement aligned to future versions. Are there any security or data privacy constraints we must follow for PropertyData/Mapbox? Do you have a preferred Codex runbook versioning strategy and a kickoff for how deliverables map to each Codex packet? What are the exact acceptance criteria for v7.6 (unit/UI tests, PDF reports, performance)? Are there GDPR/compliance requirements I should design for from day one? Are you open to continuing with v2 and v3, and what criteria will guide that decision? Best regards,

Hello, As a senior developer at Live Experts, I am well-versed in your rigorous Flutter development needs and project expectations. Having executed numerous codex-driven projects, I firmly grasp how to interact with Codex / ChatGPT to incorporate AI-assisted coding in real-time applications. This expertise is organically complemented by my proficiency in Mobile App Development for both iOS and Android platforms using Flutter. I understand the importance of adhering to strict design specifications while being able to promptly identify sequencing and dependency concerns—a necessity for your structured delivery model. In line with your favored proptech sector, I have a deep interest in prop-data, which makes me resonate with Property Stalker's purpose. It gives me an additional edge when it comes to running Codex prompts or even troubleshooting them, as my comprehensive understanding strengthens my validation ability. Being headquartered in London myself adds convenience to our periodic face-to-face meetings; however, my remote working competence is no less promising. This coupled with my proficiency in REST APIs (PropertyData, Mapbox) and PDF report generation marks me as the perfect candidate for your project. Your Flutter-driven Property Intelligence Platform has greater plans beyond version v7.6. My long-term commitment aligns perfectly with your objective of continuous development till Version 3—a phase that focuses on advanced a Thanks!

Hi there, The primary risk in AI-assisted execution is code fragmentation where generated snippets fail to align with the existing Flutter scaffold or API logic. We will solve this by applying a rigorous validation layer to every Codex output, ensuring that each prompt packet integrates perfectly with the Bitbucket repository while maintaining the integrity of the Property Stalker handbook. Here are our questions: Are the face to face meetings preferred in Central London or a specific location in the South East? Are there any specific PDF generation libraries already defined in the v7.6 scope? Our team is based in the UK and has extensive experience using Codex and AI accelerators to deliver high-performance Flutter applications. We are fully prepared to follow your structured runbook and have successfully managed long-term proptech projects from execution to launch. We provide 30 days of free post-launch support to ensure every deliverable meets your exact specifications. Let’s discuss your project today!

Hi there, A major risk in execution-heavy builds is the fragmentation of logic when integrating Codex-generated outputs into a pre-scaffolded Flutter environment. My approach ensures that every prompt packet is validated against your Context Primer to maintain architectural integrity while accelerating the v7.6 delivery timeline. I have a few questions for you before we start: Are you currently using a specific state management library like Bloc or Provider within the scaffolded repo, and what is the exact location for our first face-to-face meeting? Let’s discuss your project now!

Hi I can deliver your Property Stalker v7.6 build as a senior Flutter developer with experience using Codex/ChatGPT in structured, production workflows. The main technical challenge is executing a tightly defined, codex-driven sequence while ensuring each packet integrates cleanly with APIs like PropertyData and Mapbox, and I solve this through disciplined validation, test-first integration, and clear communication. I’m fully comfortable following detailed runbooks, adhering to strict order, and flagging sequencing or dependency risks early. I’ve worked on data-heavy, mobile-first Flutter apps that include reporting, geospatial layers, and PDF generation. Your existing designs, documentation, and scaffold provide an ideal environment for precise implementation rather than ideation. I’m interested in an ongoing relationship for v2 and v3, especially around analytics and automation. Thanks, Hercules

Hello, I’ve worked extensively with Flutter to deliver mobile apps across iOS and Android in very structured, documentation-driven environments. For example, I helped a UK healthcare client complete a complex app using strict specs and incremental AI-assisted code review—similar to your Codex-driven workflow. This gave me solid experience reviewing AI-generated code, adjusting it, and integrating cleanly with existing APIs. I’m based in South East England and comfortable attending regular face-to-face meetings around London, combined with remote work. I understand the importance of early flagging of dependencies to keep delivery on track, especially with multi-API integrations like PropertyData and Mapbox. A quick question—are the Codex prompt packets modular enough to prioritize certain features first if dependencies delay others? Also, for PDF reports, have you found any edge cases with generation to watch for? I’m ready to jump into v7.6 and help move that milestone forward on schedule. Let’s get started. Best regards.

Hello, I have reviewed the details of your project. i will work directly inside the existing flutter codebase and following the v7.6 specification step by step. since the ui designs project scaffold and api choices are already defined my focus will be clean execution and steady delivery. i will run each codex prompt in the provided order review the generated code test it locally and integrate it into the bitbucket repo with clear commits. flutter will be used for ios and android with a minimal web version where required. rest apis including propertydata and mapbox will be connected according to the handbook logic and formulas. pdf report generation will follow the defined output rules so reports stay consistent and accurate. i will flag dependency or sequencing risks early and keep documentation updated as features land. i am comfortable meeting in person regularly and continuing remotely between sessions to keep momentum strong through delivery and future versions. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you.
