About
I'm a Full-Stack Engineer who takes products from architecture and customer needs through deployment. At Crombie, I took sole technical ownership of an early-stage B2B SaaS for a US-based client, helped scale core MRR to more than 6x, and built a CRM integration that established a major new recurring-revenue channel.
I combine product judgment with hands-on engineering across TypeScript, Next.js, NestJS, AWS, APIs, integrations, and applied AI to turn customer problems into reliable production software.

Crombie
Full-Stack Engineer
♦ Took product engineering ownership of an early-stage B2B SaaS — worked directly with a US-based client as the sole developer, leading discovery, prioritization, architecture, and deployment. Stabilized critical user flows by using analytics and user-behavior evidence to prioritize the work that mattered.
♦ Designed an event-driven integration engine powering Stripe, QuickBooks, Zapier, GoHighLevel, and Karbon on a shared event bus across billing and operational workflows — processing $4.5M+ in annual payment volume.
♦ Helped scale core monthly recurring revenue to more than 6x its starting level through product improvements across billing, integrations, and critical user workflows.
♦ Built and launched a GoHighLevel CRM integration that established a major new recurring-revenue channel within six months.
♦ Opened the platform to external and AI clients through permission-scoped API keys and a scoped REST + OpenAPI surface, then mounted an MCP server exposing existing operations as tools on the same NestJS service layer, so AI agents can safely query data and execute business actions.
♦ Developed and refactored scalable Next.js, NestJS, and AWS capabilities across authentication, cloud infrastructure, APIs, and third-party services, improving maintainability and enabling safer feature delivery.
Full-Stack Developer (Internship)
♦ Architected a custom multi-domain architecture using Next.js and GCP, allowing independent portals on shared infrastructure.
♦ Automated CI/CD pipelines for containerized deployments.
♦ Owned high-concurrency Nest.js services on AWS, implementing auto-scaling and action idempotency.
Tecnosan
Full-Stack Developer
♦ Built and maintained client-facing landing pages and internal management systems with role-based authentication, operational reporting, and automated PDF generation — replacing manual workflows for several local business clients, with production systems still in active use today.
