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
OpenClaw #179331 + #179333	Concurrent OpenClaw automations could reject the same saved account before any work began, even though its credentials had not changed. Reported the race and contributed the fix so scheduled runs can share an unchanged account while still refusing replaced or revoked credentials.	✅ Reported & fix merged
OpenClaw #180308 + #180321	Routine inspection of OpenClaw’s AI tool connections printed usable credentials into terminal output and retained agent transcripts. Reported the exposure and contributed credential redaction so operators can inspect connections without revealing supported secret fields or losing saved credentials when editing the output.	✅ Reported & fix merged
OpenClaw #172174 + #172176	OpenClaw’s automation editor left a visible gap below its Create, Save, and Cancel actions. Reported the layout bug and contributed the fix so the actions sit at the bottom edge on desktop and mobile while remaining reachable by keyboard.	✅ Reported & fix merged
pkgx Pantry #14808	OAuth2 Proxy packages still used a Go runtime that trusted compromised certificate authorities. Contributed a build requirement for Go’s certificate protection and verified that a rebuilt package rejects the affected chains. Maintainers rebuilt the latest packages so pkgx users receive that protection too.	✅ Merged
OpenClaw #151374 + #151375	Chinese and single-word audio transcripts appeared as blank chat bubbles in OpenClaw. Reported the rendering bug and contributed the fix so users can read both new and saved transcripts without migrating their chat history.	✅ Reported & fix merged
Effect #6830 + #6832	Effect’s OpenAI integration left developers unable to configure supported cache settings and safety identifiers through its high-level API. Documented the missing request options and proposed a fix; upstream contributors completed the support so applications can configure cache reuse and identify end users for safety monitoring.	✅ Reported & proposed fix; resolved upstream in #7403 and #9670
Effect #6831 + #6833	Stable instructions and documents could not be marked for OpenAI cache reuse through Effect’s prompt API. Reported the gap and proposed content-level cache breakpoints; upstream contributors added support for text, images, and files so developers can choose the reusable prefix before changing content.	✅ Reported & proposed fix; resolved upstream in #7403 and #9667
pkgx Pantry #14531	The latest pkgx package for OAuth2 Proxy, used to protect web apps behind a login, was missing Go security and reliability fixes included in the official release. Contributed the build fix so pkgx users receive those patches too.	✅ Merged
Effect #8843 + #8842	An AI tool server could pass TypeScript checks yet crash because a required dependency was missing. Traced the gap in Effect's type checks and contributed the fix so developers catch the mistake before running their tools.	✅ Reported & fix merged
PostHog AI #5055 + #5056	PostHog's OpenAI Agents reports left out cached token usage, hiding how much input was reused. Reported the gap and contributed the fix so teams can distinguish cached input from fresh input when reviewing AI usage and costs.	🚀 Shipped in @posthog/ai 8.13.4
OpenClaw #161836 + #161842	Reopening an OpenClaw chat made uploaded images disappear. Traced the problem to files being moved and contributed the fix so new uploads remain visible after reloads while private file paths stay hidden.	✅ Reported & fix merged
deck.gl #10723 + #10724	Tracked misplaced hover details and controls in deck.gl's React maps to a layout bug that put them below the visualization or offscreen. Reported it with visual reproductions and contributed the fix so users see details beside the point they are exploring.	✅ Reported & fix merged
OpenClaw #160889 + #160895	OpenClaw kept resending old conversation history even after OpenAI had compressed it. Traced the lost compression state and contributed the fix so later AI tool calls keep the compacted history instead of needlessly resending the full conversation.	✅ Reported & fix merged
Effect #7015 + #7016	Investigated Effect workflows that failed before they could retry after an error. Traced the failure to retry delays with fractional milliseconds and contributed the fix so automated retries can be scheduled without firing earlier than requested.	✅ Reported & fix merged
Pitchfork #580	Upgrading Pitchfork, a tool for managing background services, broke startup on Amazon Linux ARM64. Traced the failure to its release build and contributed a fix that restores compatibility with existing Linux hosts.	✅ Merged
Convex Agent #190	Convex AI chats slowed to a crawl while an agent streamed a long tool request. Reported the slowdown and supplied a prototype fix and benchmark reproduction; maintainers later merged a fix to keep chats responsive during tool use.	✅ Upstream fix merged in #270
🖥️ ghui	Brought the Vague theme to ghui so users can match their other terminal tools. Also contributed wraparound keyboard navigation, making the theme picker loop from last to first. Maintainers shipped both in v0.4.4 (theme, navigation).	🚀 Shipped in v0.4.4
PostHog #54002	AI requests appeared under anonymous users in PostHog even though the app supplied user and session IDs. Traced the data loss and contributed the fix so teams can connect AI activity to the correct user and session.	✅ Merged
Convex #441 + #442	Stopping Convex through bun run left the Next.js server running in the background. Reported the bug and proposed a fix; the shipped solution stops both servers together, preventing leftover processes from occupying the development port.	🛠️ Shipped in the convex v1.36.0 changelog
Vague #8 + #12	Built Vague themes for OpenCode and bat so users can keep the same colors while coding with AI, reading files, and reviewing Git changes through delta and lazygit. Transferred both projects to the Vague organization.	🎨 Transferred
OpenCode #13720	GeistMono Nerd Font was bundled with OpenCode but missing from its font picker. Added the missing font option across settings and translations so users can actually select and use it.	✅ Merged
Motion Primitives #146	Installing Motion Primitives animations through shadcn left out a required package, forcing developers to add it themselves. Fixed the component registry so those components install with their dependency included.	✅ Merged
React (Indonesian) #472	Contributed the first Indonesian translation of React's "Updating Objects in State" guide, including its examples and explanations. This gives Indonesian-speaking developers a way to learn the pattern in their own language.	✅ Merged
