Game developer · backend-leaning full-stack

CS student in Thailand. I build games that unsettle people, and backend systems that stay up.

I design and build games. Right now that means Silent Ember — a two-person psychological horror game in Unity that took my region's place in the National Software Contest national final and pitched in the RMUTI CON startup track. The other half of my work is backend-heavy systems: REST APIs, a real-time bot that streams GitHub webhooks to Discord, and an npm package that self-heals failing API calls.

About

Nakhon Ratchasima · UTC+7

Hey, I'm Bannawat — a 21-year-old CS student at Rajamangala University of Technology Isan. I design and build games. With one teammate I'm making Silent Ember, a psychological horror game in Unity: the core loop, the mechanics, and the systems underneath.

Silent Ember took our region's place in the National Software Contest (NSC) national final in the entertainment-software category and earned development funding, and we pitched it in the RMUTI CON startup track. It reads what the player chooses to look at and decides the ending from that — no meter on screen, only the lantern's flame.

The other half of me is a backend-leaning full-stack developer: a Go e-commerce API, a real-time DevOps bot that streams GitHub webhooks to Discord, an npm package that auto-heals failing API calls with an LLM. TypeScript and Golang are my go-to tools; I reach for Python, C#, Unity, or Godot when the job calls for it.

  1. 2022 — 2026Game development

    Game Developer

    I design and build games in Unity and Godot — core loops, mechanics, and the systems that hold them together. Silent Ember, a two-person psychological horror game in Unity, is the current focus: it took our region's place in the NSC national final (entertainment software), earned development funding, and was pitched in the RMUTI CON startup track. I own the architecture and all the C#.

  2. 2024 — 2026Backend & full-stack

    Full-Stack Developer

    I build systems back-to-front with a backend focus — REST APIs, real-time pipelines, auth, and DevOps automation. Golang when performance and reliability matter, TypeScript across the stack. My work includes a Go e-commerce API, a webhook-driven bot, and a published npm library.

Silent Ember

In development

Unity 6 · C# · two-person team · 2022–present

A two-person psychological horror game in Unity. Explore a burned house, uncover what happened to Jonas's family, and reach one of several endings. The game quietly measures which memories you choose to read — 15 optional pieces, none on the main path — and decides the ending from that. No meter on screen: the lantern's flame steadies as you understand more.

NSC 2026
Regional representative (Northeast Thailand) at the National Software Contest national final, entertainment-software category. Received development funding.
RMUTI CON
Pitched in the startup track — market sizing, pricing, and go-to-market for a commercial Steam release.
Signature system
Event-driven architecture; 6 core systems with no per-frame Update(). The ending is gated on exploration — measured at 7% rushed vs 87% thorough in playtests.
My role
Team lead — architecture, save/load, game systems, and all C#.

Playable build coming soon.

Wakeful

Production

wakeful.dev

An uptime-monitoring SaaS I built and run in production — HTTP/DNS/SSL checks, incident tracking, multi-channel alerts, and public status pages. Real users, real billing, real on-call.

Multi-protocol checks
HTTP, DNS, and SSL-expiry monitoring, plus heartbeat pings for scheduled jobs.
Multi-channel alerts
Email, LINE, Telegram, and outbound webhooks — an incident reaches you where you actually look.
Public status pages
Shareable status pages and embeddable uptime badges for every monitor.
Stripe billing
Free and paid tiers with different check intervals — real subscriptions, real webhooks.

Closed-source — built and operated as a real product, not a public repo.

Live

GitHub → Fastify API → n8n → Discord · TypeScript

Real-time DevOps bot — GitHub webhooks into a Fastify API (HMAC verify, idempotency), through n8n, out as rich Discord embeds. Fault-tolerant, at-least-once delivery.

ai-fetch-healer

Published

npm · v1.1.0 · Request → AI → Apply → Retry

A runtime auto-healing wrapper around fetch — catches 400/422 schema mismatches, asks an LLM (Gemini, OpenRouter, Groq, Ollama) for a healing rule, patches the payload, and retries.

npm install ai-fetch-healer
Healing runsimulated
1Request fails422{ "user_name": "Ada" }
Privacy by design
Masks email, password, token, and other PII before any payload reaches the LLM.
Heuristic cache
O(1) lookup, capacity 1000 — repeat error patterns skip the LLM call entirely.
Never throws
A failed heal falls back to the original response, so the caller never breaks.
Production-tested
Caught a deprecated default model (404) in prod and shipped the fix as v1.1.0 the same day — 44/44 tests green.
