Harpreet S.

I’m a Python software engineer, AI product builder, and trading-systems developer with experience across quantitative research tools, AI-assisted web applications, Lovable/Supabase products, and migration of vibe-coded apps into independent production stacks. On the product side, I build real MVPs and internal tools with application logic, authentication, permissions, structured databases, dashboards, AI workflows, and production-ready architecture. I have built Learnube, an AI-assisted learning platform that turns YouTube and web content into structured notes, summaries, quizzes, assignments, courses, kits and concept maps. I have also worked on migrating applications away from Lovable into lower-cost, more controllable stacks using GitHub, Vercel, Supabase, direct provider integrations, and clearer deployment workflows. This helps clients reduce platform dependency, improve maintainability, and avoid expensive revision loops. My product development work includes: - Lovable, Supabase, Vercel and GitHub-based application workflows - Migration from Lovable/vibe-coded apps to independent production stacks - Authentication, permissions, user accounts and structured data models - AI-assisted workflows, LLM/RAG concepts, content processing and summaries - Dashboards, learning platforms, internal tools and operational products - Debugging, refactoring, deployment and production-readiness improvements On the trading and data side, I build Python-based research, backtesting and automation systems for stocks, futures and options. I have worked with NSE market data, options/futures analysis, Black-Scholes-based workflows, Excel/VBA automation, QuantConnect, TradingView Pine Script and ThinkorSwim-related trading logic. Clients work with me when they need: - Clean and reliable Python systems - Serious trading, data or financial-market logic - A functional MVP built quickly but thoughtfully - Lovable/Supabase apps that need debugging, scaling or migration - Someone who understands edge cases, data quality, maintainability and real product workflows If you are building a product, automation system, AI workflow, or trading/data tool that needs logic, structure and reliability, I can help you design and build it properly.
