Frontend architect and lead engineer with 15+ years building large-scale web products for enterprise, energy, telecom and fintech teams — the last 6+ years at Siemens, before that at HCL and Siemens Energy. I own the technical direction — architecture, performance, accessibility, testing and release quality — and stay hands-on in the code that delivers it.

I work across the full stack: frontend architecture with Angular, React and TypeScript, backend services with Node.js, and AI-native features built with Copilot and LLM APIs.

My work lands in three places: modernising legacy Angular and React platforms without stalling delivery, setting up design systems and micro-frontend boundaries so teams ship independently, and lifting Core Web Vitals on products where speed directly affects revenue.

Measurable outcomes

• Raised a production Lighthouse score from 20 → 97 through rendering, bundle and asset-delivery optimisation.
• Improved Core Web Vitals (LCP, FID, CLS) by 80%.
• Led an energy-platform redesign delivering a 47% performance boost and a 32% increase in customer acquisition.
• Cut release-time bugs by 63% and reached 90% unit-test coverage.
• Reduced runtime bottlenecks by 48% via memory-leak resolution and performance profiling.
• Introduced Backend-Driven Architecture, cutting development effort by 13%.
• Led micro-frontend adoption, reducing deployment overhead and enabling independent releases.

AI & AI-native

I use AI deliberately to move faster without lowering engineering standards — prototyping, automating repetitive work, and shipping AI-native product features.

• AI-assisted development with GitHub Copilot, ChatGPT, Claude and Gemini
• Rapid prototyping and scaffolding of new features
• Automating repetitive, error-prone work (tests, reviews, migrations)
• AI-native UI patterns and product integrations
