Accomplished software architect with over 19 years of expertise in developing scalable software solutions for high-traffic consumer products, serving a user base of over 100 million daily active users and handling billions of page views. My career has spanned startups and large corporations, where I've excelled in both greenfield product development and optimizing existing solutions with teams of varying sizes.

As a Principal Engineer at Marqeta, I led the architecture and design of multiple critical products, including card disputes, dashboard applications, and various end-user-facing widgets.

At plus.ai, I spearheaded the architecture and design of a high-scale cloud-based data ingestion, processing, and serving system, processing tens of terabytes of image data daily from hundreds of vehicles, all while operating under bandwidth, connectivity, and compute constraints.

At Tetration Analytics, I conceptualized and built cloud security posture management product from the ground up, aligning it with various benchmarks and security standards. This remarkable achievement was accomplished within a record time frame with a small engineering team.

In my role as Principal Engineer for Yahoo's strategic commerce initiative within Yahoo Mail, I played a pivotal role in developing and deploying personalized commerce experiences, boosting open rates and link clicks by 10-20%. We established new partnerships with multiple retailers, with a projected annual revenue exceeding $100 million.

I also architected an intent detection/fulfillment and distribution engine at Yahoo's Assistance and Search group, which led to the acquisition of over 3 million new users through the launch of branded bots on various platforms in a matter of months. Additionally, I contributed significantly to Yahoo's search ranking and relevance serving systems.

During my tenure overseeing Yahoo Answers, I collaborated with cross-functional teams, including scientists, editors, and operations, to introduce a series of backend, frontend, spam, and SEO features. These improvements resulted in a more than 10% increase in page views and a 12% boost in user engagement on resolved questions.

I am passionate about driving innovation and solving complex challenges, and I look forward to contributing my expertise to future endeavors.
