1. Full Stack & AI Engineer · Teramot

   Jun 2025 – Jun 2026 · Remote

   • Built an AI data agent end-to-end: chat UI (sidebar + full-page), inline rendering of MCP tool responses (markdown/tables/citations), an agent mode streaming live interactive UI (cards, charts) from LLM responses, and an automated evaluation suite scoring tool-selection accuracy.
   • Implemented prompt caching across 3 breakpoints (tools array, system prefix, rolling history), reducing input token cost ~90% per iteration after the first agent turn; migrated to adaptive extended thinking for Anthropic Opus compatibility and reinforced parallel tool-use.
   • Wired a Go LLM backend (Anthropic Claude SDK) to an MCP server, enabling autonomous use of ~16 stateful tools (workspace navigation, table preview, ad-hoc SQL, results-table creation); added Redis-backed history and a persistent agent-memory tool. Implemented the MCP client end-to-end (TypeScript client, Go SSE → Streamable HTTP transport, OAuth 2.1 + Dynamic Client Registration via Logto).
   • Built an in-house Go-AST → TypeScript code generator anchoring a 3-stage typed-API pipeline (AST codegen → openapi-typescript → RTK Query); retired 7 hand-written clients and permanently eliminated frontend/backend type drift.
   • Established CI/CD quality gates (drift guards, Conventional Commits, pre-push type-check + lint), scaled frontend test coverage to 80% (Vitest + MSW), and led security hardening (closed RBAC gaps, removed a hardcoded secret, fixed a Sentry PII leak, SHA-pinned all Actions and base images).

2. Full Stack Engineer · Picterus

   May 2025 – Jun 2026 · Remote

   • Built clinical features for a newborn-jaundice screening web app (React 18 + TypeScript + Vite, Redux Toolkit, React Query) used by doctors to remotely monitor bilirubin levels (TSB/TCB).
   • Implemented multi-tenant, role-based access control with Logto (OIDC) — organization-scoped tokens and per-role Admin/Doctor permissions across the app.
   • Built the measurement workflow UI: result upload, risk stratification (categories 0–5), threshold-based alert generation, and exportable Plotly clinical charts; added i18n (English + Indonesian) and timezone-aware date handling.
   • Containerized with Docker and shipped to Google Kubernetes Engine via a GitLab CI/CD pipeline with ephemeral environments for feature branches.
