Hi, I'mPraveen Kumar
Senior Frontend Engineer
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.
// 01 — about
Frontend-first, full-stack ready
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.

Product Ecosystem
Pick a company to explore its product tree, or browse all projects at once.
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.
Outlet Portal
I built the self-serve portal for individual outlets on Comixo — self-onboarding, business info, real-time incoming orders, rider onboarding and management, operating hours, user access, and payout tracking, all from one dashboard.
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.
Corporate Website
I designed and built the company's marketing website — a responsive, content-first site covering services, company info, and lead generation for startups and small-to-medium businesses.
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.
Admin Portal
I built the internal admin dashboard that runs the Cookr marketplace — managing cooks, buyers, orders, delivery partners, and payments from one interface. I implemented the data tables, order tracking, user management, and reporting tools the ops team uses daily.
Reports Dashboard
I built the analytics dashboard the business team uses to read platform health — order volumes, revenue, cook performance, rider stats, and customer trends through filterable charts and exportable tables.
Seller Portal
I built the self-serve portal home chefs use to join Cookr — registration, profile completion, and go-live in one flow, plus full menu management with pricing and availability controls for their storefront.
