I build full-stack, mobile, and AI-enabled products from architecture to production.
What I'm looking for
I've shipped production B2B SaaS, marketplaces, and cross-platform applications end-to-end as a freelance full-stack and mobile developer.
At Syl now, I founded and led technology for a two-sided B2B lead-generation marketplace serving 500+ vendors across 100+ celebration categories. I built its web and mobile platform, generating ₹13L in revenue through pay-per-lead pricing.
I created a programmatic SEO engine that generated 10,000+ indexed pages and built operational automation with MSG91 WhatsApp, Razorpay, and ML-based vendor matching. My work spans Next.js, React, Node.js, Supabase, React Native, Flutter, NestJS, Prisma, AWS, and Cloudflare.
I've also built enterprise collaboration systems, a geospatial parking ecosystem, AI voice dictation software, e-commerce platforms, WhatsApp CRM tools, and lead automation products. I enjoy taking products from requirements and system design through deployment and handover.
