Senior Full Stack Engineer · React · Next.js · NestJS · Generative AI · LLM Apps · Prompt Engineering

Based in Ahmedabad, India · 10+ years building enterprise-grade applications

I build full stack applications at the intersection of modern web engineering and Generative AI. During the day I lead frontend modernisation at LTM (Larsen & Toubro Group), rewriting legacy enterprise systems into scalable React and Next.js applications. In my own time I architect AI-integrated SaaS products from scratch.

I am especially interested in multi-model LLM orchestration, IMG2IMG AI pipelines, and building real products that use Generative AI practically — not just as a demo.

Upload one product photo → get 10 professional studio-quality images in under 3 minutes

• Hybrid AI pipeline: Gemini 3 Pro Image for hero shots + Replicate FLUX.1 Kontext for batch angle generation
• Dynamic angle selection: Gemini Vision analyses each product and recommends the best angles based on garment type, silhouette, and user's photo count setting
• 61% cost reduction achieved through provider-agnostic architecture — from $0.67 to $0.26 per 10-angle job
• LoRA fine-tuning pipeline planned on FLUX.1 Kontext Dev via Replicate for category-specific photoshoot style training
• Stack: React Native (Expo) · NestJS 11 · PostgreSQL · Redis · BullMQ · AWS S3 + CloudFront · Razorpay · Stripe
