About

Technical Architect with 8+ years of experience building and scaling products across enterprise software and SaaS. I specialise in frontend architecture, fullstack systems, and increasingly in LLM-powered applications and RAG pipelines.

At SAP Labs, I define engineering standards, drive cross-team technical strategy, and own the architecture of UI systems used at enterprise scale. I have shipped a runtime micro-frontend framework, a Go-based service broker, and a company-wide open source library — all of which are in active production use.

I thrive at the intersection of product and engineering: translating ambiguous requirements into clean, well-reasoned system designs and guiding teams to execute them with confidence.

    Bangalore, India

    • Lead technical architecture for enterprise-scale SAP UI products, defining system design, component boundaries, and cross-team engineering standards.
    • Designed and built a micro-frontend framework that dynamically generates screens at runtime, enabling product teams to ship UI independently without frontend deployments.
    • Authored a company-wide open source library adopted across multiple product teams, standardising core feature patterns and reducing duplication.
    • Built a Go-based service broker for marketplace onboarding, enabling third-party applications to integrate with SAP's platform through a unified, self-service API.

    • Designed and built the core audience-management APIs integrating Segment, powering personalisation and targeting for a product serving millions of users across South-East Asia.
    • Drove fullstack architecture decisions across multiple verticals in close collaboration with product and design.
