Chief Technology Officer
Forward Insight Co., Ltd.
Took a logistics-ERP startup from zero to paying customers in production.
Built the founding tech team and architecture for an end-to-end logistics-ERP platform — one app that tracks an operation from the ground all the way through to accounting, so profit and loss surface the moment a driver logs their last stop. Lead engineering and technical direction, and run all infrastructure as the platform engineer on PRODIGY9's platform.

Chief Technology Officer
Naxon.ai
Architected the LLM/RAG engine behind a conversational-AI platform, live with paying customers.
Set the architecture and directed the build, springboarding on PRODIGY9's platform. Designed a "brain-split" system — a stateless conversation engine over LangChain backed by a separate, event-sourced core API — so the engine can be re-seeded from the core at any time, freeing a dedicated ML engineer to focus purely on conversation quality while the core guarantees no data loss. Now leading a refactor toward a message-middleware pipeline (reply generation, guardrails, MCP invocation) and building a vibe-coding platform with built-in storage for chat-first markets like Thai users on LINE.

Founder
PRODIGY9 Co., Ltd
Founded and run a software studio shipping across multiple delivery teams.
Built and run a consulting studio that has grown to as many as ~60 people across ~10 active clients. Hand-built most of the underlying platform and ops tooling myself (Go and SvelteKit, pre-AI) — platform engineering before the term was common — to keep small teams shipping fast. Advise founders to stay lean and low-headcount on minimal but scalable tech, rather than over-staffing and over-investing in infrastructure before the first paying feature ships.

Chief Technology Officer
Muang Thai Broker Co., Ltd.
Built a 20-engineer organization as CTO across a suite of insurance products.
Inherited a small team of ~5 junior developers and grew it into a ~20-engineer organization, putting real development, ops, and QA processes in place (and owning internal IT) for an insurance group shipping gettgo.com and GettGo Hero, its agent-facing portal. Initiated the extraction and rewrite of the gettgo.com frontend — previously a tangle of Rails-interpolated JavaScript that throttled performance — into a fast, independently optimizable stack, freeing the marketing team to SEO-tune at will, which matters when the product is sold on marketing.

Lead Software Engineer
T-Box Co., Ltd.
Helped win Thailand's first SEC portal license — built Bangkok's first white-labeled ICO portal.
Led the build with a team of 3 and carried the team through the SEC's audit, fielding the regulator's technical questions on a brand-new asset class. To address the SEC's central fraud concern, designed wallet-ownership verification via MetaMask signatures — the backend issues a signable challenge, the user signs in MetaMask, and the backend verifies it to prove live control of the address — alongside the KYC/AML the new platform required. Left once the license was secured.

Director of Engineering
Omise Co., Ltd.
Doubled Omise's engineering org from ~15 to 30+ while raising the hiring bar.
Established the engineering hiring and onboarding process from near-scratch with the HR team — screening a high volume of CVs, designing the interview flow, and personally reviewing candidates' take-home assignments to hold a high quality bar through fast growth. Stayed hands-on throughout with code review, mentoring, and coaching across the team.

Senior Developer
Omise Co., Ltd.
Built core payments infrastructure and the full SDK suite at Omise, a regional payments company.
Refactored payment configuration into a cascading system — system defaults, per-PSP defaults, then per-merchant overrides — so settings could be tuned dynamically at every level. Generalized the internal KYC model to handle multiple countries from a single codebase, unblocking the Singapore market launch. Built out essentially the entire SDK offering of the time, designing APIs across languages to be markedly more ergonomic than the alternatives available.

Senior Developer
Hyperworks Co., Ltd.
Shipped Swift and React in production at their launch.
Built the API and web servers plus the native iOS and Android apps for a Thai-language study app, working in Swift and React while both were brand new and still churning. Also helped author a book on Go microservices.

Technical Co-Founder
Suffixlab Co., Ltd
Built a content-driven mobile app and the CMS powering it, end to end, two-person team.
Delivered both halves myself: the native iOS and Android apps users actually saw, and the full backend feeding them — backoffice servers, the content API, and the CMS that managed it all. Designed a deliberately minimal architecture shared across both native clients to keep them at parity in quality and behavior. A teammate built features on top of the architecture I set. Along the way assembled a lightweight Go scaffold from idiomatic libraries that became the direct predecessor to PRODIGY9's `fx`, which I still rely on heavily at PRODIGY9 today.

iOS / Android / Node.js Developer
Oozou Ltd.
Built a Node.js pub/sub system controlling every device in a hotel from a single mobile app.
Designed a text-based, PEG-parsed TCP protocol — and the Android SDK that spoke it — to let one app control the TVs, air conditioning, and other devices across a medium-sized hotel, since few existing protocols fit at the time. On a separate project, added SIP dialing to an iOS community app via gossip, an open-source Objective-C wrapper I built over the C-based PJSIP library on Grand Central Dispatch.

Developer
Hua Lumpong Co., Ltd.
Shipped five mobile apps across five platforms — iOS, Android, Windows Mobile, Bada, and BlackBerry.
Built and delivered distinct native apps for several clients, including a major newspaper, spanning five mobile platforms and toolchains. Also built a code-submission verifier for the company hackathon that accepted entries and validated them automatically.

Founder
2nitedesign Co., Ltd
Built and open-sourced Sider, an idiomatic C# client for Redis when Redis was brand new.
Designed the client's API to mirror Redis commands closely; it was listed on the official Redis clients page as the more idiomatic C# option for talking to Redis.

Senior Developer
Ecartstudio Co., Ltd.
Reduced map-tile storage by over 50% on an in-house mapping engine.
Built a tile-compression tool for a proprietary mapping engine: a batch pipeline that re-encoded terabyte-scale PNG tile sets to 8-bit indexed PNGs, reducing storage footprint by over 50%. Documented the engine's internals across ~40 wiki pages, and architected a Silverlight/DeepZoom viewer — handling the API integration behind a Google Maps-compatible interface so existing client code needed no changes.
