Owned performance at scale for a national serverless platform (~26M users), building an in-house distributed load-generation and resilience platform from scratch to enable safe pre-launch validation. Delivered a Python/Locust framework sustaining ~350k RPS (3× peak), plus long-duration workload simulation and failure-mode testing that improved tail-latency stability during burst traffic.

Developed and maintained API test automation suites and baseline performance checks for microservice and event-driven architectures, integrating them into CI/CD quality gates. Designed mutation testing strategies and embedded exploratory/quality practices to reduce regressions reaching staging and production.

Engineered CI/CD deployment gates using Terraform + AWS ECS and implemented Pact contract testing to prevent breaking API changes from reaching production. Built distributed load-testing frameworks (Locust on AWS) and led failure-mode analysis for distributed systems to improve resilience and validation strategies.

Engineered CI/CD deployment gates with Terraform and AWS ECS, enforcing API compatibility using Pact contract testing to prevent breaking changes from reaching production. Established the organization’s first distributed load-testing frameworks (Locust on AWS) and led failure-mode analysis bridging functional testing and early reliability engineering.

Applied context driven testing and risk based quality practices
Facilitated threat modelling and failure mode analysis
Built Bash tooling for log parsing and telemetry
Profiled Java systems and supported observability migration

Led validation of Android audio driver stacks, defining synthetic and real-world audio test streams across hardware–software integration layers. Set a structured testing strategy for Audio HAL and ALSA components to verify embedded audio behavior.

Built hardware CI and automation infrastructure for Set-Top Box systems, enabling automated middleware and driver-level testing on physical devices. Developed remote hardware test farms and an IP-based testing framework for direct command injection and live telemetry streaming, enabling global remote debugging to reduce on-site support needs.

Scaled a grassroots cycling initiative into a multi-day national tour by owning end-to-end operations and real-time incident response. Designed structured communication and telemetry systems for event operations that were later adopted as an industry model.

Developed low-level C device drivers for Set-Top Box systems, implementing memory management and real-time hardware control logic. Debugged I2C and UART communication at the signal level using oscilloscope-based waveform analysis.
