I’m a technology executive and co-founder of Knock.com, a fast-growing fintech company that revolutionizes how people buy and sell homes.

Over the last few decades, I've built numerous startups from the ground up  and scaled to 400+ people. I've held positions ranging from a solo engineer, tech lead, and chief architect to executive/CTO level. I studied computer science at Stanford University.

My last few ventures:

  1. Founder/CEO @ScoreTravel — pre-seed venture funded in March 2024
  2. Co-founder/Chief Labs Officer/Chief Architect @Knock.com — pre-IPO, 2B valuation, raised ~$650m
  3. Co-founder/CTO @Chirpme — 500 Startups Incubator (1st batch), acquired by Match Group
  4. Founding Lead Engineer @SportsYapper — raised ~$12m, #1 on iOS sports app in the UK
  5. Fractional CTO/Board Advisor @TapDating (consumer-tech)

I love crafting the right mix of — people, culture, and modular, extensible technology to drive execution with visibility and confidence. I’ve scaled engineering and data science/AI teams to over 50+ members.

I'm still hands-on; my superpower is seeing through the forest and problem-solving. I'm highly technical, encompassing a broad spectrum of technologies and disciplines:

  1. Frontend (React/Next.js, SvelteKit)
  2. Product and platform backend services (Node.js/TypeScript, Golang)
  3. Idempotent distributed transaction orchestration (message queues, SQS/SNS, Kafka, Redis, Temporal)
  4. Data engineering (Python, Airflow/Prefect, Dbt, Spark/Scala, warehouses/Snowflake/ClickHouse, Databricks and Lakehouse architectures)
  5. Identity & authN (OAuth2, OpenID), authZ (Zanzibar), Zero Trust security architecture
  6. Cloud infrastructure and security (AWS, containers, ECS/Kubernetes, VPC/networking, service mesh architectures)
  7. Databases (MySQL, Postgres, ElasticSearch, DynamoDB)
  8. Machine learning engineering lifecycle (training, evaluation/validation, inference/deployment). Algorithms include - regression, classification, clustering, collaborative filtering, gradient boosting, CNN, deep learning, GPT

My deep technical understanding and experience can be leveraged to guide your startup uniquely. I’m interested in co-founder or CTO/chief architect roles (fractional or advisory-type welcome).
