# Nimish Nandwana — Lead Mobile Engineer > Portfolio site: https://nimishnandwana.com > Location: Gurgaon, India > Contact: nimishnandwana@gmail.com > LinkedIn: https://linkedin.com/in/nimi0112 > GitHub: https://github.com/nimi0112 --- ## Summary Lead Mobile Engineer with 9+ years building mobile products that reach millions of people. Native Android, Flutter, and Kotlin Multiplatform — with a focus on performance, architecture, and AI-augmented workflows. Available for senior and lead mobile engineering roles — especially where there is interesting platform depth, AI integration, or a small team building something ambitious. Stats: 10M+ users · 5 markets · 50+ A/B tests per quarter --- ## About I've spent the better part of a decade making software that fits in people's pockets. What keeps me in mobile engineering isn't the platforms — it's the discipline. A 16ms frame budget doesn't negotiate. A crash rate above 0.5% shows up in your store rating within a week. You learn to care about precision fast. At Deutsche Telekom Digital Labs I lead a team shipping a streaming platform to 10M+ users across Europe. Most of my work these days sits at the intersection of architecture, performance, and team process. Outside of my day job I build things that scratch my own itches — PaisaTracker (self-hosted finance agent), LIC Agent Toolkit, NZ Job Hunt Agent. I'm also genuinely excited about where AI tooling is going for software teams. I wrote the AGENTS.md rules and Cursor project configuration that now govern code review across all our apps. --- ## Stack ### Android Kotlin, Java, Jetpack Compose, MVVM / MVI, Hilt, WorkManager, Room, Coroutines, Flow, Material 3 ### Flutter & Cross-platform Flutter, Dart, BLoC, Riverpod, Platform channels, KMP, Ktor, SQLDelight, Compose Multiplatform ### Performance & Native JNI / NDK, C++, Baseline profiles, R8 / ProGuard, LeakCanary, Perfetto, Systrace ### Quality & Security TDD, JUnit5, Mockito, Espresso, OAuth2 / SAML, Biometric auth, Certificate pinning, PCI DSS ### AI Tooling Cursor, Claude API, AGENTS.md, Project rules, OpenClaw, DeepSeek, AWS Bedrock, MCP integrations ### Platform & DevOps Firebase, Play Console, Fastlane, GitLab CI, GitHub Actions, Hetzner VPS, Cloudflare --- ## Experience ### Deutsche Telekom Digital Labs — Lead Mobile Developer Dec 2022 – Present · Gurgaon · Current role Lead an 8-engineer mobile org delivering an Android-first streaming platform at 10M+ MAU across 5 European markets.
