Kartikey S.

I've built infrastructure handling 5M+ data points/month and systems serving 1M+ users generating $7,500+ per converted lead for clients. 17+ production projects shipped, from early stage startups to platforms handling millions of users. 📈 WHAT I'VE BUILT (WITH NUMBERS) → hotinbox.ai : Automated their entire lead infrastructure handling 5M+ data points/month. Built scraping to enrichment pipelines that generate $7,500+ per converted lead. → Blue Nelumbo : Architected an LMS backend serving 1M+ concurrent users/month ($300 avg course price). Moved them to serverless on AWS Lambda, cutting infrastructure costs while scaling revenue. → Apartment Eleven Eleven: Shipped a full production-ready platform (not an MVP) in weeks. Complete tech infrastructure from zero to live. 🧠 HOW I WORK: AI-Augmented, Architecture-Owned I use AI tools (Cursor, Copilot) to move fast but I design the architecture myself. No vibe-coded spaghetti. Clean infrastructure saves you real money when you scale and start paying cloud bills. 🛠️ TECH STACK Backend: NestJS, Node.js, Express, Fastify, REST APIs, JWT Frontend: React, Next.js, TypeScript, Tailwind CSS, Three.js Databases: PostgreSQL, MongoDB, MySQL, Redis, Pinecone DevOps: AWS, Docker, Prisma, Git Automation: n8n, API integrations, data pipelines 📩 If you need a developer who ships fast, thinks in systems, and builds infrastructure that prints money send me a message.
