I am an entrepreneurial technologist based out of San Francisco Bay Area in California, USA. I help early to mid-stage startup CEO's as their technical counterpart acting as the company's fractional or interim CTO.

As a technologist, I bring the expertise of more than 25 years of building and launching products. I honed my skills in product architecture and engineering management at leading companies, including Yahoo, where I designed and delivered the company's global application architecture.

I built my entrepreneurial muscle at a half-dozen Silicon Valley startups, providing technical leadership to global, multi-disciplinary teams working in the mobile, edtech, and fintech sectors, among others. A collaborator and builder at heart, I specialize in efficient and effective product development, cloud migration strategies, and digital transformation.

I work with the teams to evaluate clients' technical capacity, identify gaps, and gage opportunities. Then, as builders do, I get to work to make those opportunities real.

As an entrepreneur, I cofounded my first company in 2003. I exited (unprofitably, I must add) after 16 months when my inexperience in other aspects than technology brought me down. "Brought me down" may not be the right metaphor, "elevated me up" could have been equally apt since I learnt things that nobody can teach but experience and failure. I also helped built the first online Bengali magazine Parabaas in 1997. Ask me about this sometime. I have some interesting stories to tell.

As an writer and songwriter, I work in my native language Bengali.

Things I Can Do

Fractional CTO

I offer three different levels of engagement as a fractional CTO.

One is more advisory in nature, another one is strategic and the third one is operational.

Technology Audit

This is a one to two week engagement where I do a in-depth intake of your engineering operations (technology, people, process) to provide a status report along with a advisory roadma.(

Strategy Day

Technology Strategy Day is when the technology and other functional leaders of the company participate in a daylong activity facilitated by me to identify the business’s strategic opportunities and challenges that need addressing technologically.

The goal of the TSG is not to find a solution that can be implemented right away (which is impossible to do beyond the most trivial issue), but to bring to surface and align around the two or three most promising opportunities and difficult challenges which need to be addressed technologically and plan to address them with a timeline.

At the end of the Strategy day, I will debrief about the common learning and provide a roadmap as to how to address the most potentially impactful issues for immediate addressing.

A Few Accomplishments

  • I was one of original developers of Apache Traffic Server, which is a top-level Apache project. The product was developed by Inktomi in early 2000. When Inktomi went down in dot-com bust, Yahoo bought this product. Later Yahoo donated it to Apache.
  • I was the architect for Yahoo's global architecture of the Commerce properties, which consolidated disparate codebase stacks from tens of countries to an unified central architecture.
  • I helped Credit Sesame replatformize it's main product and also move operations to the cloud.
