Sabin S.

I help founders and product teams build AI-powered SaaS products and get them production-ready: full-stack development, LLM features, and clean deployment from one senior engineer. With a focus on delivering scalable and maintainable solutions, I transform ideas into launch-ready products. Whether you're starting from an idea, an MVP, or an AI-generated app that works in the demo but breaks in the real world, I turn it into something you can launch, scale, and charge for. WHAT I DO: - AI & LLM features: agents, RAG over your data, chatbots, and workflow automation using OpenAI, Anthropic, LangChain, and LlamaIndex - SaaS MVPs & new features: Next.js/React frontends with Python (Django/FastAPI) or Node backends, Stripe subscriptions, auth, dashboards, and admin tools - Rescue & production-readiness: cleanup of inherited or AI-generated codebases, bug fixing, performance, security basics, testing, and CI/CD - Cloud & DevOps: AWS/GCP, Docker, Terraform, and automated deployments PROJECTS I'VE SHIPPED - Khalti: digital wallet and fintech engineering - Tapnett: NFC digital business card platform with analytics and subscriptions - cr8rs: monetization and streaming platform for creators (Full details in my portfolio below.) TECHNOLOGY STACK I USE: Python, Django, FastAPI, Next.js, React, TypeScript, Node.js, PostgreSQL, MongoDB, Supabase, Stripe, AWS, GCP, Docker, Terraform. I also work with React Native and GraphQL when a project needs them. HOW I WORK: I focus on the business problem, not just the ticket. You get clear scope up front, regular progress updates, practical technical decisions, and ownership from development through deployment. I write code that's clean, documented, and maintainable by your next developer. I AM BEST FIT IF: - You have an AI product idea and need it built end to end - You have an existing app that needs AI features - You have an MVP or AI-generated codebase that needs to be production-ready Let's discuss how I can help bring your project to life.
