SDET specializing in fintech systems and AI-assisted automation. I build scalable test frameworks that reduced defect triage by 50% and websites that score 100/100 on Lighthouse — always with engineering precision.
SDET with an M.Sc. in Electrical Engineering, specializing in fintech systems. I build scalable test frameworks and AI-driven resilience tools — cutting defect triage time by 50% and release cycles by 35% via Jenkins/Docker pipelines.
With 9+ years of engineering experience, my background spans Linux embedded systems (firmware testing), full-stack web development, and leading the adoption of LLM-assisted QA tooling (Claude Sonnet, Gemini) for automated root-cause analysis.
I build custom websites that score 100/100 on Google Lighthouse. No bloated builders—just pure HTML/CSS/JS deployed on Vercel for instant loading.
