- Application Engineer on the IT manufacturing systems team at Delta Electronics Thailand: CI/CD, Kubernetes, full-stack web, and production line support for MES tooling in an air-gapped network.
- I build and run the shared data platforms other teams plug into: a central Kafka cluster, a NiFi cluster, streaming pipelines out of the MES, and a log analytics platform on OpenSearch.
- I usually own what I build end to end, from scoping and cross-department coordination to presenting it and supporting the people who use it.
- Before corporate work I spent five years founding and operating a multiplayer game-server platform (FiveM and RedM), which is where most of my backend and systems experience started.

Kafka-to-HTTP bridge. Retries, dead letters, flows, cluster mode and a live console. One binary, one YAML file. |
Type-safe HTTP APIs for Go. Declare a struct once and get validation, OpenAPI docs, a TypeScript client and Zod schemas. |
Self-hosted SSO and identity platform. OIDC, RBAC, realtime fan-out, and cluster-safe background jobs. |
|
Log analytics for the factory. Go collectors and workers, OpenSearch indices, and Teams alerts while production is still affected. |
Shared Kafka and NiFi platforms other IT teams plug into, with CDC from the MES, Spark streaming jobs and Grafana monitoring. |
A multiplayer roleplay platform I founded and ran for five years: game server, Lua systems, web shop and infrastructure. |

The streamable HTTP client now reports the real HTTP status when a gateway or framework answers with a JSON error body, instead of failing with an unrelated parse error. |
A flaky SSE transport test raced a 1 ns client timeout against a mock server and panicked on a nil error about half the time on Windows. It is deterministic now. |

Decoding a notification into a reused value no longer keeps |
Each replay callback gets its own copy of a stored event, so a callback that changes a message can no longer corrupt what later replays send. |
|
OAuth with PKCE enabled now refuses an empty code challenge or verifier, instead of quietly finishing the flow without PKCE. |
Requests are no longer parsed several times on the way to the handler. Profiling showed those extra JSON reads took most of the time and memory on large tool calls. |
The client listener keeps the retry interval it was created with instead of reading a package variable, which fixes an intermittent |
|
Tool calls with a custom TLS config or a SOCKS5 proxy share one transport instead of building a new one each time. 300 calls open 1 connection instead of 300, and each call is about 25 times faster. |
Markdown converters are pooled, so crawls keep scaling past 8 workers. The maintainer measured about 905 pages per second at 32 workers, against 559 before. |

Tests for the accessibility package of a Go terminal UI engine: value redaction, screen reader announcements on three platforms, and mode switches. Coverage went from 65% to 91%. |
