Hiren Variava

I help companies design and build scalable data and AI platforms that drive real business outcomes.

With 20+ years of experience across fintech, enterprise data platforms, and cloud-native systems, I work with startups and enterprises as a fractional CTO or senior technical advisor to solve complex data and platform challenges.

My focus areas include:

- Data platform architecture and modernization (analytics, ML, real-time systems)

- AI-driven applications (RAG, NLP, data pipelines, decisioning systems)

- Identity resolution and external data integration

- Platform strategy, system design, and execution leadership

I have led enterprise-scale initiatives, including cloud migration and data modernization at First Republic Bank, and architected fraud and risk decisioning systems at Accertify (American Express). As a founder, I have built and launched AI-driven platforms end-to-end, combining product thinking with deep technical execution.

Typical engagements include:

- Defining platform and data strategy

- Designing scalable architectures and system blueprints

- Leading execution across engineering and data teams

- Stabilizing or accelerating high-risk or stalled initiatives

I am hands-on with engineering teams to unblock data pipelines, AI implementations, and platform issues when needed and focus on delivering practical, high-impact solutions that teams can operate and scale long term.
