}About
I'm a Senior iOS Developer based in Bangalore, currently building the mtu Go! Care app for Rolls-Royce Power Systems (via ITTI, client Bosch) — helping service technicians and fleet managers monitor mtu engines, generators and power-system assets in the field.
My work spans MVVM and Clean architecture, Swift Concurrency, Combine, enterprise OAuth authentication, offline-first networking, and CI/CD with Fastlane and Jenkins. Before automotive, I built real-time chat products on XMPP and WebRTC, energy-monitoring dashboards for IoT and SCADA data, and OTT streaming for iOS and tvOS.
Experience
Feb 2026 — Present
Building the mtu Go! Care app — modular SwiftUI screens for asset details, service schedules, fault diagnostics and parts ordering, backed by REST/GraphQL and OAuth. Driving SwiftUI + Swift Concurrency adoption and CI/CD improvements with Fastlane and Jenkins.
Feb 2025 — Jan 2026
Led iOS development for Smart Energy Monitoring apps — real-time dashboards for IoT, BMS and SCADA data, custom Core Graphics gauges for kW/kWh/voltage, secure role-based access, and Fastlane-driven App Store delivery. Mentored junior developers.
Jul 2024 — Feb 2025
Migrated 100+ modules from Objective-C to Swift, introduced GraphQL + Combine reactive flows (crash rate down 40%), refactored legacy UIKit to SwiftUI, and pushed crash-free users above 99.5% with Crashlytics-driven fixes.
Mar 2024 — Jul 2024
Built SDK features in React.js for cross-platform apps, improved performance metrics by 15% across 10 digital platforms, and worked with design-system tokens for native/web visual parity.
May 2021 — Feb 2024
Built real-time messaging apps (SafeTalk, Weiilla) on MirrorFly and an OTT platform (VPlayed) — XMPP + WebRTC chat flows with 30% lower latency, reusable chat components adopted across client apps, and Instruments-driven memory-leak elimination.
Sep 2019 — May 2021
Refined GroupXConnect and OurCommunityApp — chat and map features, Core Data optimization, push notifications and deep linking with FCM, and mentoring interns on Swift and Apple HIG.
