Software developer specializing in Flutter, Android (Kotlin), and full-stack web — with production experience in hardware-integrated systems (BLE, USB) for clinical and consumer products.
Real problems clients bring me — and what I actually do about them.
We scope the actual problem — not a feature list, the outcome you need.
→I propose the architecture and timeline before any code is written.
→Regular check-ins, working increments — no silence until the big reveal.
→Deployed, documented, and handed off cleanly. Not abandoned at 90%.
Each engagement is scoped around your product, not a fixed package.
Each project is a story — a real problem, a solution, and something learned.
Real numbers from production systems — not estimates.
Owned the Opinion Trading module in production for Playerzpot, a fantasy gaming app — shipped features and fixes directly to a 1 Crore+ user base.
PlayerzpotDelivered 6+ production features for a meditation & habit-tracking app using Jetpack Compose, serving 1 Lakh+ daily active users.
Level SuperMindRestructured state flow propagation across a multi-module Compose app to eliminate unnecessary recompositions during fast habit-check cycles.
Level SuperMindDesigned and shipped a strict 3-layer Fastify 5 backend (routes → services → repositories) for a production matchmaking platform.
Chemistry.IRLArchitected a shell-orchestrated monorepo with shared BLE/USB hardware core, shipping Android tablet and Flutter Web targets from one codebase.
Collertal MedicalMigrated large legacy Java modules to Kotlin + Jetpack Compose on a production POS app, improving maintainability and reducing crash rates.
Reboot Technologies
I didn't get into development just to write code.
I got into it because I like understanding how things work — and more importantly, how they break. Most apps today feel disconnected from real people. They look good, but they don't think. That's what I try to change when I build.
I work mainly with mobile systems — Flutter monorepos with multi-app orchestration and web targets, Android with Kotlin and Jetpack Compose, React Native — and backend architectures with Node.js, Fastify, and PostgreSQL. I focus on clean architecture, hardware integration (BLE, USB serial), and systems that hold up under real-world conditions. Beyond tech, I spend a lot of time thinking about user behavior and how small decisions shape big outcomes.
Not perfect. Still learning. Always building.
Kotlin, Dart, TypeScript, Node.js
B.Sc. (Computer Science)
Built 8+ production systems
Built the Sarcopenia clinical diagnostic platform from scratch — a Melos-managed Flutter monorepo with a shell orchestrator app that launches five standalone diagnostic sub-apps (Balance Plate, Gait Speed, Chair Stand, Hand Grip, Anthropometry) on demand. Each sub-app runs independently or within the shell via GoRouter deep links with patient session handoff. The same codebase targets Android tablet and Flutter Web. Also developing the UVThera and Hepabuddy clinical platforms with BLE/USB sensor integrations and offline sync.
Built and optimized 6+ production meditation and habit-tracking features using Jetpack Compose and MVVM for 1 Lakh+ daily active users. Documented 52+ custom feature modules, significantly increasing onboarding speed and code maintainability.
Migrated large legacy Java modules to Kotlin and Jetpack Compose on a production POS application. Re-engineered UI screens to improve layout performance, reduced overall app crashes, and designed modular architecture schemas.
Owned and optimized the Opinion Trading module utilized by over 1 Crore users. Built and integrated custom native Android libraries directly into the core Flutter gaming project, resolving critical performance blockages and scaling telemetry tracking.
Structured and honest — not buzzwords. Click categories to inspect my technical capability meters.
Building single-codebase universal applications (mobile and web) with hardware telemetry integrations, multi-app orchestration, and scalable modular designs.
💡 Beyond languages: architecture isolation policies, problem decomposition heuristics, async scheduler telemetry, and computing trade-off analysis.

Things I've been thinking about — on building, systems, and craft.
Most apps fail not because of bad code, but because nobody thinks about how people actually use them.
Clean architecture is not about layers. It's about clarity.
Building fast is easy. Building right is not.
Real-world APIs don't behave like documentation. That's where the real learning happens.

Inspired by Derek Sivers' /now page movement.
I have quit social media noise (Instagram & Snapchat) for the rest of the year. Instead of posting to algorithms, I journal, share core engineering concepts, and track my milestones right here. This is my logs page, where I run without excuses — practicing the “One More Swing” mindset.
