Full-stack engineer & architect — Gurgaon, India
I design and build production software end-to-end: a 300,000-line transport SaaS built solo, delivery apps live on the stores, and C++/NDK tooling that flashes STM32 boards from a phone. One engineer, the whole stack — app, backend, firmware.
Selected work
Six of twenty-plus shipped products. Every case study includes the stack, the scale and the engineering that made it work.
Multi-tenant employee-transport & ride-dispatch SaaS — solo-built, ~300k lines, live in production.
All-in-one delivery & marketplace super-app — customer, merchant and driver flows in one Flutter platform.
An Android phone that replaces a PC as an STM32 production programmer — native C++ over USB-OTG.
Self-hostable industrial IoT platform — MQTT fleets, TimescaleDB telemetry, rules, alarms and OTA at 2,000 msg/s.
Ten offline construction calculators that draw a to-scale diagram as you type — built to a 598-line spec.
An engineering-tools platform: 25 hardware & firmware calculators, a paid API, and an embeddable widget system.
Capabilities
Most teams need three specialists for this. Hiring one person who spans them means fewer hand-offs, faster decisions, and interfaces that actually fit.
Store-ready apps that survive real users — payments, maps, offline-first data, push, native modules when Flutter or React Native isn't enough.
Full platforms, not just frontends — multi-tenant SaaS, dashboards, e-commerce, realtime tracking, payment webhooks and the databases underneath.
Where software meets solder — firmware, industrial HMIs, USB tooling and fleet platforms. The rare stack that debugs from the UI down to the logic analyzer.
How we'll work
The same agency-grade process behind EzeFare and Dasho: written proposals, milestone acceptance, audit trails.
A short call, then a written proposal with milestones, acceptance criteria and a price. No vague estimates.
Architecture before pixels — data model, APIs, auth, infra. You see the plan before the first commit.
Working builds you can touch every milestone — store-ready APKs, staging URLs, live dashboards.
CI/CD, monitoring, store compliance, post-launch iteration. I've operated what I've shipped.
