ABOUT
Ten years on one platform, on purpose.
I started on Android in 2016 and stayed. Depth on one platform is what lets me argue about module boundaries, trace a startup regression to its real cause, and tell a product team what a requirement will actually cost.
Most of my work is enterprise: apps in logistics, healthcare and automotive, where a crash is a support queue and an inaccessible screen is a procurement problem. I got WCAG-certified for mobile because that argument kept coming up and I wanted to stop guessing.
I’m based in Noida and open to Senior, Staff and Principal Android roles: India, UK, Europe or remote.

WORK
Constraint, decision, result.
Enterprise work sits under NDA, so these lead with the constraint, the decision and the result. The first is open source - verify it yourself.

Constraint
Airline bookings are messy: polymorphic segments where a flight and a ground transfer occupy the same slot in a list, partial data, and a user who only wants to know when to leave for the airport.
Decision
Segments modelled as a sealed interface in a pure-Kotlin domain layer, so the compiler enforces exhaustive handling. Multi-module Clean Architecture keeps business logic away from the framework, and AssetManager is provided through Hilt specifically so no Context leaks into data.
Result
Stateless, preview-ready composables with custom-drawn timelines and parallax headers, driven by one StateFlow. Entirely public - read the architecture yourself.

Compose at scale, without a performance regression

Modularization
Wear OS
READ THE CASE STUDY →
Multi-module enterprise codebases where a rewrite was never an option and cold start had drifted to 3.6 seconds. Compose adoption usually makes startup worse before it makes it better.
Incremental migration governed by architecture design reviews, with Perfetto traces as a release gate rather than a post-mortem tool. Baseline profiles and module boundaries decided from trace evidence, not preference.
Cold start 3.6s → 1.6s. UI jank down 28%. 99.5%+ crash-free users sustained across releases.

2019–2022
Offline-first sync for apps used where signal isn’t
Horizon Blue and 10+ B2B / B2C apps · via SunTec
Room
WorkManager
Retrofit
SSL Pinning
R8
Field and clinical users lose connectivity mid-task. Naive sync produced conflicting records and support tickets, while checkout flows were shedding users at the payment step.
Offline-first architecture with an explicit conflict policy and WorkManager-backed retry, plus a hardened network layer - SSL pinning and R8 obfuscation - because health and finance clients get security-reviewed before they get shipped.
Data consistency up 35%. Checkout drop-off down 18%. API latency down 22%.
Also shipped
Public, older, still mine - and the rest of the client roster.
AVIATION / TRAVEL

Jun 2017 - Jul 2017
Golden Era Royal Group (GERG)
Android Developer
Cab-booking Android app for the Bengaluru market, with features comparable to Ola and Uber.
Built the LetzCab ride fare calculator. Pricing logic and end-user workflows.
TECHNICAL LEADERSHIP
I don’t just ship features. I help teams ship better.
ARCHITECTURE
Governed MVVM and Clean Architecture standards across multi-module Android codebases, and ran the design reviews that kept them from drifting.
PEOPLE
Mentored and technically guided 5 Android engineers. Pull-request turnaround came down 30% as review habits changed.
QUALITY
Owned code review, automated testing and release quality gates. Regression defects down 25%.
DELIVERY
Designed and owned CI/CD on GitHub Actions, with static analysis and release workflows I maintain.
PRODUCT
Primary technical point of contact for stakeholders: translating business requirements into mobile solutions with product, backend and QA.
ENGINEERING
Depth, grouped by capability.
Not a logo wall. Each group says how I use the tooling and where the work shows up.
Android platform
Compose for new surfaces, interop where a rewrite would not pay for itself. Ten years of the platform's sharp edges.
Kotlin
Jetpack Compose
XML views
Large-scale Compose adoption across enterprise codebases at TCS.
Accessibility
Screens tested with TalkBack, contrast and touch targets treated as part of done.
WCAG 2.0
TalkBack
WCAG 2.0 Accessibility for Mobile Apps, certified 2026.
Performance
Traces first. I do not tune what I have not measured, and the trace goes in the PR.
Baseline profiles
Coroutines
Cold start 3.6s → 1.6s; UI jank down 28%.
Reliability
Stability benchmarks set per release, with crash triage owned rather than delegated.
Firebase Crashlytics
JUnit
Mockito
Espresso
99.5%+ crash-free users sustained across production releases.
Delivery
Pipelines that fail loudly on tests, static analysis and quality gates before a build reaches a reviewer.
GitHub Actions
Gradle
detekt
ktlint
Play Console
Regression defects down 25% after the gates went in.
Security
Finance and healthcare clients security-review before they ship, so hardening is part of the build, not a later pass.
R8 / ProGuard
Root detection
OWASP awareness
Network and binary hardening across B2B/B2C apps at SunTec.
Architecture
Domain stays pure Kotlin; data implements what the domain declares; module boundaries follow the work, not the org chart.
Clean Architecture
SOLID
Solution design
Public reference in AF-Bookings and WeatherApp.
Cross-platform & AI
3 years of Flutter/Dart alongside the Android work, plus a year applying generative AI in the delivery workflow.
Flutter
Dart
Gen AI tooling
Self-reported skill-years, LinkedIn headline.
WCAG 2.0
Accessibility is part of the definition of done
Certified for mobile apps, and I test with TalkBack rather than assume. Uncommon for Android leads, and it keeps enterprise clients out of procurement trouble.
HOW I STRUCTURE THINGS
Dependencies point inward. Always.
Domain is pure Kotlin and knows nothing about Android. Data implements interfaces the domain declares. UI holds no logic worth testing twice.
It sounds academic until a project is three years old and still cheap to change.
UI
Stateless composables, one StateFlow per screen
Navigation
Domain
Pure Kotlin. No Android imports at all.
UseCases
Sealed models
Repository interfaces
Data
Implements what the domain declares
Serialization
MEASURED, NOT CLAIMED
Cold start, cut in half.
A Compose migration across multi-module enterprise codebases, governed by Perfetto traces on every release rather than investigated afterwards.
