What I'm looking for

I'm looking for remote B2B or contract work where I can build production TypeScript products, LLM evaluation and observability systems, and agent-orchestrated delivery workflows.

I've shipped LLM evaluation and observability capabilities at Lumigo, including scoring, trace-grid score columns, evaluation filters, and an evaluations management route. I was the top author of the AI/LLM observability product, contributing 642 commits in seven months across a 109-package monorepo.

At Oreamnos, I led frontend development for a document-management platform in Angular 21 and Nx 22, delivering rich-text editing, reporting dashboards, collaboration support, training workflows, and WCAG AA accessibility. I also built a Playwright E2E suite with 169 test cases and integrated Keycloak-backed authentication.

I've modernized Angular platforms at Kaseya and Pulseway, cutting build time from 272 to 99 seconds and reducing vulnerabilities from 65 to 3. At ICE Mortgage Technology, I built and optimized 25+ UI features, improved load time from roughly 4.5 to 2.7 seconds, and supported Angular, React, and Aurelia interoperability.

I work across TypeScript, React, Next.js, Angular, Node.js, and NestJS, and I use multi-agent orchestration, guardrails, evaluation pipelines, and observability as part of day-to-day delivery. My side projects include an AI job-search Telegram bot and agent-orchestrated TypeScript automation services.
