What I'm looking for

I'm looking to lead and build production SaaS products, APIs, operational systems, and LLM-powered applications, with end-to-end ownership across architecture, delivery, and high-quality engineering practices.

I've led end-to-end production Next.js, TypeScript, and API projects at Azumo, from architecture and implementation through deployment and Scrum delivery. I build authentication, authorization, and provider-backed asynchronous workflows using queues, workers, polling, retries, and webhooks.

At NeosCloud, I led NeosCRM's transition from AngularJS to a framework-agnostic, type-safe Progressive Web Application built with Web Components. I introduced TypeScript, Web Components, PWA practices, SASS, Redux, Material Design, reusable UI patterns, Storybook documentation, and project generators.

I've also improved SAP CPQ calculation performance by 56.7% by analyzing large formula sets and implementing faster algorithms with Python, JavaScript, KnockoutJS, and HTML. My work spans React, Node.js, SQL-backed integrations, operational analytics dashboards, CI/CD, and LLM-powered application development.
