Sr. Android Developer & Technical Lead
Building Android experiences for 9.4 years — from platform internals to shipped product.
I build and ship enterprise Android platforms: AOSP device work for Cisco & SpectraLink handsets, real-time WebRTC/SIP communication systems, and consumer apps used by hundreds of thousands of people. Currently a Technical Lead at Matellio, based in Jaipur, India.

About
Enterprise platforms, real-time systems, and a decade of Play Store apps.
I work at the layer where Android meets hardware and infrastructure — SELinux policies, Device Owner & MDM integrations, JNI bridges into native code, and the migration work that keeps enterprise fleets on supportable OS versions. Alongside that, I've built full-stack real-time systems from scratch: a WebRTC push-to-talk platform with an Android client, Node.js backend and React admin console, and I led the Java-to-Kotlin, MVVM modernization of a podcast app serving 50,000+ episodes to a large listener base.
Earlier in my career I designed, built and shipped 40+ consumer apps across VPN, healthcare, e-commerce, real estate, entertainment and finance — the full loop from planning through post-launch support, monetization and Play Store optimization. I care about code reviews, mentoring, and leaving systems more maintainable than I found them.

Senior Android Developer
Matellio Inc. · Remote
Sept 2022 — Present · 3.9 yrs
Designing and building features for enterprise Android apps on SpectraLink and Cisco devices — JNI layers into native code for performance, stability work, and cross-site collaboration adding features to the 87xx/92/95/96 device series.
SpectraLink Enterprise VoIP Platform
Android development for enterprise VoIP devices (Versity V95/V97, Cisco CP840/CP860). Led migration from Android 10 to Android 14 across system apps. Set up SELinux policies, Device Owner functionality and MDM integrations (Airwatch, TestDPC). Maintained BizPhone (SIP/VoIP over CUCM & Asterisk), PTT, SAFE, Diagnostics and Sound Stage. Built 50+ automated QA cases with Cucumber & TestNG to replace manual regression testing.
Push-to-Talk Platform (Full-Stack)
Built a complete PTT system from scratch — Android client (Java/Kotlin), Node.js backend and a ReactJS admin portal. Ran 5+ proof-of-concepts on MediaSoup WebRTC for real-time voice, and wrote a 162-page technical spec plus an 80-page user manual. Handles real-time messaging, channel management, QR-based auth, device pairing, MDM integration and role-based access for Super Admin, Store Admin, Manager and Employee tiers.
Auddia / Faidr — Radio & Podcast App
Modernized a streaming app covering 6,200+ AM/FM stations and 50,000+ podcast episodes. Converted the codebase from Java to Kotlin and refactored to MVVM + Repository pattern, moving API calls out of Activities into ViewModels. Integrated TensorFlow Lite for ad detection, wired to the Discovr Tracks API to replace ads with podcast content — cut app size by 30% and resolved lag issues, while reviewing code and guiding other developers on the team.

Feb 2017 — Sept 2022 · 5.5 yrs
Designed, built and maintained 40+ Android apps across VPN, healthcare, e-commerce, real estate, entertainment, productivity and finance — owning the full cycle from planning through post-launch support, subscriptions & in-app purchase monetization, and Play Store release management. Worked with real-time chat, VoIP calling, payment systems, location-based features and offline-first design. Notable shipped products: OnlyVPN (OpenVPN-based VPN client), PMedia (VoIP communication), Dr.Live+ (healthcare appointments), and a full catalog of client apps — see Work below.
Work
42 apps, every category imaginable.
Pulled straight from the project log — VPNs, VoIP, fintech dashboards, wedding apps, government portals, tarot platforms. Most were client work for Knollinfo, built, shipped, and eventually retired when the contract ended. Filter by category, or see everything.
