Senior Software Engineer in Test

Quality systems that make teams faster and software safer.

I design automation strategy, embed quality ownership across engineering teams, and build delivery workflows that shorten feedback cycles without sacrificing confidence.

Over the last decade I have led quality transformation across mobile, web, and API products, coached engineers on shift-left testing, and introduced AI-assisted quality workflows for mission-driven software teams.

Measured impact from quality leadership

The core thread across my work is consistent: build the right level of automation, move quality closer to the team, and reduce risk where it matters most.

10+

Years in test automation, quality strategy, and engineering leadership.

80%

Reduction in post-release defects after quality model transformation.

70%

Improvement in test execution speed across mobile, web, and API suites.

40%

Year-on-year testing efficiency improvement through tooling and process refinement.

What I do

Senior-level quality engineering across strategy, systems, and coaching

Automation Strategy

I design lean automation systems with selective UI coverage, broad API and integration coverage, and critical-path E2E protection.

  • Risk-based test prioritisation for business-critical flows
  • Cross-platform automation for Android, web, and backend services
  • Faster feedback through pragmatic pyramid design

Quality Leadership

I help teams move beyond QA as a gate and toward quality as a shared engineering discipline.

  • Quality Assistance model rollout across engineering organisations
  • Developer coaching on shift-left testing and quality ownership
  • Release readiness, monitoring, and regression prevention

AI + Workflow Design

I evaluate and implement AI-assisted workflows where they materially improve velocity or signal quality.

  • LLM-assisted PR regression analysis and documentation support
  • Testing approaches for non-deterministic and AI-powered features
  • Automation that reduces manual coordination overhead
