What I'm looking for

I want to keep building full stack features for B2B SaaS in a remote, distributed team—owning architecture and delivery, leading integrations (SSO, collaboration tools), and expanding AI features while continuously improving the development workflow.

I’m a Full Stack Developer with 4 years of experience designing and building complete features for a B2B SaaS platform in a remote, distributed team. I work across the full product lifecycle—from technical planning to production delivery—with direct involvement in architectural decisions.

I’ve led end-to-end feature ownership and frequent code reviews, helping the team ship with confidence. I’ve driven architectural migrations, including migrating the codebase and “20+ data collections from MongoDB to PostgreSQL,” and delivering a major UI redesign with a “new component framework based on Tailwind CSS” after the “migration from Preact to React.”

I also focus on enterprise-ready capabilities and modern developer workflows. I worked on SSO with “Microsoft Entra ID and Okta,” built integrations with “Slack, Webex, and Microsoft Teams,” and supported AI adoption through “automatic monthly performance summaries” and “on-demand text generation” for users, while incorporating Claude Code and GitHub Copilot into my daily workflow.
