We ship the backend
that holds the front end up.
Allwyn Labs is an engineering studio building web apps, mobile apps, landing pages, and AI-powered SaaS. Our engineers have shipped production systems behind fintech, IoT, and marketplace platforms at companies like Intuit and Mercedes-Benz R&D — now we build them for you.

What we build
One team, the whole stack.
No hand-offs between agencies for design, backend, and infrastructure — the same engineer who architects your database designs the screen your users tap.
Web development
Full-stack web apps on React, Next.js, and Spring Boot — built for the traffic spike, not just the demo.
Mobile development
React Native apps with native-feel performance, push notifications, and offline-first data sync.
Landing pages
Conversion-focused marketing pages that load fast, read clearly, and turn visitors into signups.
AI integration
LLM-powered features — search, agents, copilots, and automation — wired into your existing product.
SaaS builds
Multi-tenant SaaS from schema to billing — subscriptions, entitlements, and role-based access done right.
Front end, back end, DevOps
CI/CD, Docker, and cloud infrastructure so what you ship on day one still runs cleanly on day one thousand.
E-commerce platforms
Storefronts with catalog, cart, checkout, and payment gateway integration — built to handle real inventory and real orders.
SEO
Technical SEO baked into the build — clean markup, fast load times, structured data, and sitemaps that get you found.
Recent builds
Platforms in production, not prototypes.
Two full marketplaces, built end to end — data model, APIs, infra, and the UI on top.
Rentiqo
A peer-to-peer rental marketplace connecting owners and renters — booking flow, trust & verification, and payments running on a Spring Boot backend deployed to Oracle Cloud Infrastructure, with a React web app and React Native apps for iOS and Android.
TradeNexus
A B2B import/export sourcing and quoting platform — buyer-supplier matching and RFQ workflows on a Cloudflare edge stack for global, low-latency access.
Who's building it
The engineers behind Allwyn Labs.
A small studio, not a subcontractor chain — every project is built directly by the engineers on this page.
Nikhil H. Kulkarni
Full-Stack Engineer14+ years in production software, most recently as a Software Development Engineer II at Intuit, where he architected a Redis-based microservice that cut processing time 2–3x and built a Drools-driven spam engine that improved filtering effectiveness by 70–80%. Before that, at Mercedes-Benz R&D, he built the event-driven cloud infrastructure behind an IoT platform serving millions of devices at 99.9% uptime.
Holds a Master's in Computer Science (4.0 GPA) from San Francisco Bay University, and is a named inventor on three filed patents spanning cargo tracking and peer-to-peer asset exchange systems.
