I build fast, polished web interfaces with React and Next.js — and go as deep into the backend as the product needs, with NestJS, Kafka, and gRPC.

I'm a frontend-first engineer who cares deeply about what users see and feel. I build polished, fast interfaces with React and Next.js — then go as deep into the backend as the problem needs, with NestJS, Kafka, and gRPC. After 3+ years leading frontend across Cookr's consumer platforms, I now build Comixo.AI — AI agents that own business workflows for food brands.

Control Tower

I built Cookr's real-time operations dashboard — a single live view where the ops team monitors 800+ orders a day, tracks riders on the ground, and drills into customer, cook, and rider details instantly. Designed for high-volume, time-sensitive workflows where spotting an issue seconds earlier matters.

AI-Powered Commerce Platform

I built the conversion-focused onboarding site for Comixo — a multilingual, AI-native white-label commerce platform for India's food and grocery operators. Content-rich Next.js site targeting restaurant owners and marketplace builders, covering the platform's 3 apps, 4 engines, and Atlas AI.

Diabetes Care Suite

I developed an end-to-end diabetes care platform: 3 React Native apps plus a React admin dashboard, shipped to the Play Store with 10K+ downloads. Patient app — OTP login, doctor appointments, medicine orders with prescription upload, lab search, in-app chat, health records. Health Coordinator app — daily schedules, lab pickups, km/time tracking, vitals. Doctor app — appointments, patient stats, and follow-ups in real time.

Place Order Web App

I built the customer-facing web app for ordering home-made food from local cooks. I implemented cook browsing, menus, cart, and checkout with real-time order status — using Redux for the cart and order state flows, in a responsive UI optimised for quick ordering.

Tenant Dashboard

I built the multi-tenant dashboard businesses use to run their Comixo-powered marketplace — outlets, delivery zones, orders, and payments in one place. I implemented role-based access control, app configuration, and engine-level settings so operators control their branded platform without touching code.

Organic Food Marketplace

I built the consumer platform for Nourisho — an organic, clean-label food marketplace. I designed a trust-first UI for browsing preservative-free products, from fresh produce to packaged goods, matching the brand's healthy-living positioning.

Admin Portal

I built the customer-facing portal of a B2B SaaS platform where dental labs outsource CAD design. I implemented scan-file uploads, an order pipeline (Live → Design Completed → In Production → Done), 3D design downloads, multi-role access, integrated payments, and a video tutorial system.

Designer Portal

I built the designer-side companion to the Customer Portal. CAD designers receive assigned orders, manage their design queue, upload completed 3D designs, and message customers inside each order — with every action feeding straight back into the customer's order status.

Home Cook Marketplace

I built the public-facing website for Cookr — a hyperlocal marketplace connecting home cooks with buyers. It presents the full platform story: end-to-end ordering, third-party delivery, multiple payment methods, and the Cookr Coins loyalty programme — hand-coded HTML/CSS for maximum performance.
