CTO & Full-Stack Engineer ยท Delhi, India

About

I'm an engineering leader and full-stack developer with 8+ years of experience delivering scalable web, Android, and AI-powered products. I co-founded Designare Solutions, a design and development agency where I've built, mentored, and led a 15-engineer team while shipping enterprise React/Next.js + Node/PostgreSQL solutions for clients ranging from startups to MNCs.

I'm hands-on with AI and use generative AI for code generation, testing, and documentation, cutting delivery time and costs. I also advise companies on AI integration and automation, and co-founded DeepStory, a short-form video app with ML-driven content recommendations, HLS streaming, and a Cloudflare video pipeline.

Before Designare, I spent 4 years as a freelance full-stack developer, delivering 20+ Android apps and backend systems end-to-end. I hold a B.Tech in Electronics and Communication from M.S.I.T, Delhi.
