I lead and build software for messy real-world workflows: ERP platforms, financial operations, inventory systems, AI-assisted operations, internal tools, and customer-facing portals. I care about fast iteration, clean product behavior, data correctness, and production systems that stay understandable after they scale.

• 🏗️ Core builder of Farmio's product stack across ERP, backend services, portals, workers, deployment, and operational tooling.
• 🧾 Design correctness-first database flows, including SERIALIZABLE transaction isolation for money, inventory, reconciliation, and other high-integrity workflows.
• 🤖 Led AI product work including an analytics assistant and Chat Order AI Agent, with reported productivity gains of 70% for analytics work and 60% for customer service workflows.
• 🔭 Own production hardening across health checks, observability, OpenTelemetry tracing, deploy scripts, and operator documentation.
• 📄 Build business-critical document systems including invoice PDFs, credit-note workflows, font rendering fixes, retry/timeout handling, and regression coverage.
• 💸 Reduced AWS S3 storage by 48%, translating to roughly 50% cost savings.
• 🌍 Contribute upstream fixes to tools I use, including deck.gl, OpenClaw, Effect, Convex, PostHog, Pitchfork, Opencode, ghui, Motion Primitives, React docs, and Vague.

Project	Contribution	Status
Effect #8843 + #8842	Traced a tool crash to a missing dependency that TypeScript had failed to catch. Reported the bug and contributed the fix so incomplete MCP servers fail type checks before they run.	✅ Reported & fix merged
PostHog AI #5055 + #5056	Found cache token counts missing from OpenAI Agents traces in PostHog. Reported the gap and contributed a fix so AI usage reports include cached input.	🚀 Shipped in @posthog/ai 8.13.4
OpenClaw #161836 + #161842	Traced disappearing chat images to a lost file reference when OpenClaw moved uploaded files. Reported the bug and contributed a fix so previews survive history reloads without exposing private paths.	✅ Reported & fix merged
deck.gl #10723 + #10724	Traced misplaced tooltips and widgets to a layout bug in deck.gl's React integration. Reported it with visual reproductions and contributed the fix so they stay aligned with the visualization.	✅ Reported & fix merged
OpenClaw #160889 + #160895	Found OpenClaw resending conversation history that OpenAI had already compressed. Traced the lost checkpoint, reported the bug, and contributed a fix verified against the live API.	✅ Reported & fix merged
Effect #7015 + #7016	Traced failed production retries to timer storage that rejected fractional milliseconds. Reported the bug and contributed a fix so retries are scheduled without shortening the delay.	✅ Reported & fix merged
Pitchfork #580	Traced Pitchfork's failure on Amazon Linux ARM64 to a release build requiring a newer system library. Contributed a fix that pins the build environment, then verified it on Amazon Linux 2023.	✅ Merged
Convex Agent #190	Traced severe chat lag to long, streamed tool inputs. Reported the bug and supplied a prototype fix and benchmark reproduction before maintainers merged the upstream fix.	✅ Upstream fix merged in #270
🖥️ ghui	Contributed the Vague theme and wraparound keyboard navigation for the theme picker. Maintainers shipped both changes in v0.4.4 (theme, navigation).	🚀 Shipped in v0.4.4
PostHog #54002	Traced AI requests appearing under anonymous IDs in PostHog to discarded user and session data. Contributed the fix so Vercel AI activity stays linked to the correct user and session.	✅ Merged
Convex #441 + #442	Found Next.js still running after stopping Convex with Ctrl+C through bun run. Reported the shutdown bug and proposed a fix so both development servers stop together.	🛠️ Shipped in the convex v1.36.0 changelog
Vague #8 + #12	Built Vague themes for OpenCode and bat, then transferred both projects to the Vague organization. The bat theme also works with delta and lazygit.	🎨 Transferred
OpenCode #13720	OpenCode's font picker did not include GeistMono Nerd Font. Added the font option across settings and translations.	✅ Merged
Motion Primitives #146	Found that installing some animation components through shadcn omitted a required package. Fixed the component registry so react-use-measure installs automatically.	✅ Merged
React (Indonesian) #472	Contributed the first Indonesian translation of React's "Updating Objects in State" guide so readers can learn it in their language.	✅ Merged
