Senior mobile / React Native engineer
I am strongest where React Native meets native Android/iOS, player reliability, backend/API boundaries, release quality, and team execution. At OTTPlay, a 10M+ download mobile product, I worked as Senior Mobile Engineer / Mobile App Team Lead and helped reduce playback failures from 11% to 1.5%. WittyKeys adds live Android AI product proof; Infinity Pillars adds seven years of full-stack mobile/web delivery, including two years serving as team lead for an 11-12 person team.
Built production Android apps with Java/Kotlin, API integration, Play Store release cycles, mobile UX constraints, and the debugging habits that still matter in React Native work.
Delivered React Native and Android apps, React/Next.js web apps, Node/NestJS backends, ERPs, dashboards, logistics, video, and on-demand workflows. Served two years as team lead for an 11-12 person team while staying close to architecture, code review, QA handoff, and releases.
Served two years as mobile team lead at 10M+ download scale via Wrocus / HT Media. Worked across React Native rendering, native Android/iOS player paths, streaming reliability, release readiness, PR review, and product iteration from real usage signals.
WittyKeys proves I can take an AI-enabled Android product to the Play Store. AI-SDR and SFOS show the same product discipline applied to workflow automation, QA, evals, and release confidence.
WittyKeys is an Android AI keyboard and writing assistant for bilingual/Hinglish communication. The senior engineering work was productizing the hard edges: keyboard trust, permissions, overlay behavior, billing entitlements, quota safety, Firebase backend boundaries, release checks, logs, and Play Store polish.
Owned senior mobile execution across React Native, native Android/iOS player paths, streaming edge cases, app performance, release readiness, sprint planning, PR review, QA handoff, and stakeholder communication.

View repo groupThese grouped systems are earlier code-derived portfolio samples. They are included to show breadth across mobile apps, dashboards, backend services, logistics, education, legal-tech, restaurant operations, and esports; they are not presented as actively maintained current products.
Compact supporting proof for specific freelance/client categories where breadth matters more than a full case study.
Earlier product build / legacy code sample. Included to show breadth and implementation experience; not actively maintained.
I am a strong fit where a team needs someone who can own mobile architecture, debug production issues, coordinate backend/API work, improve release quality, mentor engineers, and still ship hands-on across React Native and native Android/iOS.
