I've built QA from the ground up at Abacus.AI for Chat LLM, Abacus Agent, and CoWork, defining coverage, release gates, and quality benchmarks for AI-driven mobile and web products.

I validate LLM prompt behaviour, model response quality, workflow reliability, APIs, and backend systems end-to-end. I built Maestro automation integrated with GitHub Actions, increased regression coverage by 30%+, and investigated AI/ML anomalies through Coralogix logs and observability signals.

Previously at CRED, I owned quality for critical fintech journeys including card payments, lending, BNPL, and card management. I helped maintain a 99.8% crash-free rate, led QA for a card-management revamp serving 13M+ users, and managed App Store and Play Store release cycles.

I'm most effective in fast-moving teams where quality is shared early, release risks are surfaced clearly, and production signals guide better decisions.
