Full-Stack Developer for End-to-End Bug Testing & Fixing — AI Interview Platform (Cloudflare + Next.js + Gemini)

@techsty2014

Hey there, I will audit and patch Talenser across your 12 phases with fixes at root, delivering the bug report, security/performance scan, and production go/no-go per system. Screening question: D1 is edge-replicated SQLite, so versus Postgres you lose JSONB, native vectors, LISTEN/NOTIFY, stored procedures, and you inherit a single-writer bottleneck and a ~10GB per-DB ceiling. For Talenser this means embeddings must stay outside D1 (KV + Workers AI BGE, as you do), AI-cost and admin analytics need batched aggregation rather than heavy ad-hoc queries, and DO-backed chat should persist via Durable Object storage or R2 rather than synchronous D1 writes during spikes. Stack: hands-on with Workers + Hono, D1, R2, KV, Durable Objects, Razorpay webhooks (HMAC + idempotency), and Gemini/Vertex via server SDKs. Happy to share phase-wise timeline and milestone breakdown post-NDA. Looking forward to discussing further. Best regards, Faizan

Hello, I’m a full-stack developer with strong experience in debugging complex systems, ERP platforms (including ERPNext), and API-heavy architectures. I’ve worked on real-time apps, payment integrations, and AI-based workflows, and I’m comfortable going deep into code—not just surface-level testing. Relevant Experience: • Backend debugging (Node.js, TypeScript, serverless environments) • Payment systems (Razorpay lifecycle, webhook validation, idempotency) • Auth systems (JWT, OTP, OAuth, RBAC) • Real-time systems (WebRTC, sockets, event-driven flows) • AI integrations (API orchestration, scoring pipelines, async jobs) Timeline (7–10 days): Day 1–2: Code review + infra + auth Day 3–5: AI, proctoring, assessments Day 6–7: Billing, matching, WebRTC Day 8–9: Admin, chat, security Day 10: Final fixes + report Budget: 28000.00 INR Milestones: Initial audit report Core fixes (auth/AI/billing) Full system fixes Security + final sign-off Screening Answer: Cloudflare D1 is a serverless SQLite-based DB, unlike PostgreSQL which is a full relational DB. D1 has limitations like weaker concurrency handling, limited joins/complex queries, and eventual consistency challenges—important for your real-time, multi-user system and transaction-heavy modules like billing and chat. Ready to start immediately and deliver a production-ready system. Best Regards, JP

Hi I’ve worked extensively with Cloudflare Workers, D1, Durable Objects, and AI integrations (Gemini, VAPI), handling full-stack debugging and production hardening. I can audit your entire system and deliver clean, code-level fixes within timeline. Do you want fixes pushed phase-wise or after full audit? Will staging include all third-party integrations (Razorpay, VAPI live)? Relevant Projects I’ve Worked On: 1. Hospital ERP – full backend and frontend integration 2. Restaurant ERP – POS, order management, and reporting 3. Attendance Management Software – employee tracking and reports 4. Custom Software – tailored solutions for various business processes 5. Website Development – dynamic, responsive websites with CMS and database integration 6. AI chatbot lets connect for qaulity work - already have experience on same its my core work

Hello, I understand you need a full-stack QA engineer to deeply audit and fix your AI-powered hiring platform, covering everything from Cloudflare infrastructure to AI interview flows, billing, and security. I can perform end-to-end code-level testing, identify root-cause issues, and apply clean fixes across all 13 phases. I focus on production readiness, security hardening, and performance optimization to ensure a stable launch. Quick question: Do you want fixes pushed directly to your main repo or reviewed via staged PRs? Best regards, Thiran360AI Team

I have hands-on experience working with serverless and backend systems, including API debugging, auth flows, and third-party integrations like Razorpay. While I have not directly used Cloudflare D1/DO in production, I have worked on similar distributed backend setups and can quickly adapt. I have also worked on AI-integrated systems and API-based workflows. A relevant project is a real-time gaming platform where I debugged backend issues, optimized APIs, and stabilized WebSocket flows under load. This involved production-level debugging, performance fixes, and system reliability improvements. Timeline (10 days): Day 1–2: Codebase audit + infra review Day 3–6: Core systems testing (auth, AI, billing, WebRTC) Day 7–8: Fixes + validation Day 9–10: Security checks + final report Milestones: 1. Audit + bug report 2. Core fixes (auth, billing, AI flows) 3. Remaining fixes + security checks 4. Final validation + documentation D1 vs PostgreSQL: Cloudflare D1 is SQLite-based and optimized for edge workloads, but it lacks advanced features like strong concurrency handling, complex joins at scale, and mature transaction support. For your use case, limitations may appear in high-concurrency operations (chat, WebRTC state), complex queries, and transactional consistency compared to PostgreSQL.

Hey, This isn't just testing; it's a full system audit that requires finding and fixing bugs at the code level. That's the kind of work I do all the time. I've worked on complicated AI-driven systems that used APIs, real-time workflows, and automation pipelines. It was very important that they were stable, easy to debug, and had clean fixes. I'm fine with going deep into backend logic, following problems across services, and fixing them at the source. Experience that is relevant: Debugging full-stack systems, such as API flows, authentication, data pipelines, and real-time features Good at automation, AI integrations, and making sure workflows work. Experience with webhooks, billing flows, and handling errors Able to work with modern stacks and cloud-based architectures without any problems How to do it: Systematic phase-wise audit (auth, AI flows, billing, and real-time systems) Find the root causes, not just the bugs on the surface. I focus on production readiness — making sure the system is stable before real users come in. Timeline: 7–10 days (aligned with your scope) Happy to review the codebase and get started

@bunnyb36

As a seasoned full-stack developer with a strong background in AI and cloud infrastructure, my skill set aligns perfectly with the requirements of your Talenser project. Having previously worked on complex systems similar to yours at a GenAI startup, I've gained extensive experience working with important technical components you've mentioned like Cloudflare Workers, Durable Objects, VAPI, Vertex AI, and GraphQL. This familiarity will contribute to a faster understanding of the codebase and more accurate bug testing and fixing. One aspect that makes me uniquely qualified for this role is my ability to approach problems holistically: trace the source code to understand the logic before addressing any fix. I don't simply identify surface-level issues but dig deep into the system to ensure patching is done at the root, which is precisely what you need. Additionally, having worked with face detection and OCR technologies in relation to proctoring previously, I'm confident I could efficiently validate Talenser's ML-based proctoring system.

@aaronrobs

⚡️IF YOU’RE NOT HAPPY, YOU DON’T PAY⚡️ I’ve reviewed your detailed scope and fully understand the need for a deep code audit, bug discovery, and patching across Talenser’s complex AI-driven platform. Handling Cloudflare Workers, D1, Durable Objects, and ML-based proctoring is right in my wheelhouse. Before diving in, are there any critical areas or recent issues you'd like to prioritize? What’s your biggest concern about the current stability or security of the platform? I’d love to discuss your project further. Even if we’re not the perfect fit, you’ll still receive a complimentary consultation. Regards, Aaron Roberts
