With over 9 years in modern software engineering, I specialize in full-stack architecture where rock-solid backend microservices meet fluid, responsive mobile interfaces. My experience covers everything from low-level Android system integration (AOSP/AAOS, BLE, JNI/HAL) to massive-scale distributed event streaming (Kafka, RabbitMQ, Spring Boot, Docker).
I've engineered Singapore's leading ride-hailing infrastructure with CDG Zig (ComfortDelGro), architected next-gen smart door lock security for ASSA ABLOY (Kwikset & Weiser), built high-traffic real-time streaming platforms with KhudiVentures and NeeoPal, and currently architecting Spozon—a 16-microservice containerized sports court ecosystem.
Microservices, Event-Driven, PostGIS, Redis Caching, Docker, OpenTelemetry & Observability.
Android SDK, Jetpack Compose, Flutter, AAOS, BLE, NFC, SIP telephony & Native WebRTC.
A multi-role sports court booking platform (Players, Coaches, Coordinators, Venue Owners) designed with 16 isolated Spring Boot microservices containerized via Docker Compose, backed by Kafka event streams, PostGIS spatial queries, and distributed OpenTelemetry tracing.
Multi-role UI for Players, Coaches, Coordinators, and Venue Owners with real-time WebSockets.
Centralized routing, authentication validation, circuit breaking & Eureka service discovery.
Spatial radius queries for venue & court discovery with Redis caching for microsecond availability checks.
Micrometer, OpenTelemetry, Prometheus, Grafana, Loki (logs) and Tempo (distributed tracing).
Complete sports court booking and venue management ecosystem featuring a multi-role Flutter mobile client and an event-driven Spring Boot architecture of 16 containerized microservices orchestrated via Docker Compose.
Engineered mobility and ride-hailing modules for ComfortDelGro (CDG Zig) in Singapore. Handled real-time taxi booking, live trip tracking, digital payments, and high-concurrency event handling.
Architected and developed an end-to-end Android smart home lock solution for industry-leading Kwikset & Weiser smart locks (500K+ downloads each). Secure lock/unlock via Bluetooth Low Energy (BLE) and NFC keycard authentication.
Engineered Android Automotive OS (AAOS) and AOSP features for vehicle head units. Implemented FMVSS-compliant safety rear camera interface, AIDL IPC communication, and hands-free telephony.
High-traffic matrimonial platform (5M+ downloads) and e-commerce marketplace (BIKJAA: 1K downloads). Architected subscription-based profile listings, AI-driven matchmaking recommendation engine, and peer-to-peer WebRTC video calling.
Social communication platforms featuring live streaming, interest matchmaking, and audio/video conferencing infrastructure handling over 100,000 concurrent users. Neeo Messenger reached 1M+ downloads on Google Play, and RingTok reached 10K downloads.
Engineered native audio conferencing applications by customizing low-level WebRTC C++ codebases with master-slave architecture for 50+ concurrent participants. Integrated Sofia SIP server for web-to-PSTN routing.
Architected FMCSA-compliant commercial vehicle fleet logging communicating with Electronic Logging Devices (ELDs) via BLE. Also engineered live video examination proctoring systems using Agora.
From deep-level communications research to leading enterprise engineering teams.
Architected the ASSA ABLOY smart door lock solution utilizing secure BLE and NFC access control protocols with GraphQL microservices. Previously engineered Android Automotive (AAOS/AOSP) telephony suites, rear camera FMVSS safety compliance, and AIDL IPC for automotive head units on a 156-engineer team.
Designed end-to-end multi-role Flutter application and built a distributed Spring Boot microservices ecosystem of 16 containerized services orchestrated via Docker and Docker Compose. Configured Apache Kafka & RabbitMQ event streaming, PostGIS spatial venue search, Redis caching, and OpenTelemetry observability.
Led 5-member engineering team delivering matrimonial platform DIL KA RISHTA (5M+ downloads) and e-commerce platform BIKJAA (1K downloads). Implemented AI-driven matchmaking, WebRTC audio/video calling, and subscription billing via Google Pay.
Managed high-concurrency real-time social applications (Neeo with 1M+ downloads, Gather, RingTok with 10K downloads) supporting 100K+ concurrent users with live video streaming, Agora SDK, WebRTC peer-to-peer calling, and in-app wallet integrations.
Customized native WebRTC stack implementing master-slave architecture for scalable 50+ participant conferencing. Optimized call quality with DSP noise cancellation, Protocol Buffers, and Sofia SIP server web-to-PSTN gateways.
Developed cross-platform communication with Janus media servers, Rocket.Chat, and transit tracking apps (Slide Cab, Locate My Bus, My Order Box) with geofencing, MQTT location feeds, and NFC verification.
Comprehensive technical toolkit built over 9+ years of production delivery.
Industry-recognized certifications in distributed streaming, containerization, cloud, DevOps, and mobile architecture.
Rigorous foundation in distributed computing, advanced data structures, algorithms, operating systems internals, networking protocols, and software architecture principles.
Currently open to Senior Mobile / Backend, Staff Engineer, and System Architect opportunities worldwide. Open to relocation and remote engagements.
