Full Stack Engineer at Cygnis who cut a client's AI vendor bill by over $60k a year.
What I'm looking for
At Cygnis, I architect backend systems for a production SaaS platform and built an AI-powered PR review agent that reduced review time from 15–20 minutes to about 5 minutes per PR.
I replaced a client's third-party AI service with a custom vector store and crawler, reducing their bill by over $60k a year. I care about engineering outcomes measured in money and time saved in production.
At Q-Solutions, I was the sole developer and technical owner of an internal no-code website builder SaaS. I handled its research, architecture, and full-stack implementation from scratch.
I work with startup founders who need an investor-ready MVP built alongside them, not for them. I'm open to freelance projects and technical partnerships.
