Senior Full-Stack & AI Engineer | LLM Apps

I'm a senior full-stack engineer with 6 years of experience building and shipping production software end to end — from architecture and backend to web, mobile apps and cloud deployment. I currently lead multiple live products as the sole senior engineer, so I'm used to owning a project completely and delivering without hand-holding. What I build for clients: - AI features that work in production — LLM-powered apps, RAG and semantic search, structured data extraction, and AI chat assistants with confidence checks and human fallback, so they stay reliable with real users. One WhatsApp AI assistant I built handles 100+ customer conversations a day. - WhatsApp & workflow automation — order capture, customer support and CRM flows that turn messy customer messages (including Hinglish) into clean, structured data your team can act on. - Full-stack web and mobile products — B2B e-commerce platforms, multi-tenant SaaS, healthcare platforms with ABDM/ABHA integration, and cross-platform Flutter apps published on the Play Store and App Store. - Real-time and compliance-heavy systems — including a drone airspace-compliance platform that validates flight plans against restricted zones in real time. Tech: Next.js, NestJS, TypeScript, Python, Flutter, PostgreSQL (pgvector), Redis, AWS, Docker, OpenAI / Gemini / Anthropic models, n8n. How I work: clear scope upfront, regular progress updates, clean documented code, and a focus on the business outcome — not just the tech. If you have a product to build, an AI feature to add, or a manual process to automate, send me a message with what you're trying to achieve.
