What I'm looking for

I'm looking for a fast-paced startup where I can own fullstack development and build 0→1 products end-to-end. I've done this before, scaling a platform to 2000+ users across 5 enterprise clients as a founding engineer. I thrive on hard problems: architecting scalable systems, optimizing performance, and shipping fast without breaking things.

SDE I with 3+ years building B2B SaaS at scale. As a founding engineer, led end-to-end fullstack and UI/UX, scaling the platform to 2000+ users across 5 enterprise clients. Worked closely with leadership to validate new verticals in legal AI tech. Mentored junior developers along the way.
