Biologist turned developer.
I build websites and product interfaces for small businesses and product teams, using React, Next.js and TypeScript. Currently a Frontend Developer at Unixdev Co., Ltd. in Bangkok.
My biology background shapes how I work: form a hypothesis, change one variable, measure the result.

Three problems, three working products
A closer look at what I built, the decisions behind it and what each project makes possible.
- exp-01
Perd Wai
Planning interface with example assumptions; full screenshot includes the forecast. View full size screenshot of Perd Wai Next.js · TypeScript · Tailwind CSS · Vitest · Playwright
- hypothesis
- Aspiring café owners need to see how rent, setup costs and daily sales affect their opening plan.
- my contribution
- Built the planning interface, calculation engine and forecast views, with Thai/English copy and browser-saved plans.
- key decision
- Keep the forecast deterministic. Optional AI explains the calculated results but cannot change the numbers or the decision signal.
- result
- Founders can compare three scenarios, inspect a six-month forecast and export a plan. The tool is ready for user validation; market validation is still pending.

Layer 3D
Desktop landing page and its interactive printer preview. View full size screenshot of Layer 3D Next.js · TypeScript · React Three Fiber · GSAP · Tailwind CSS
- hypothesis
- Customers need to understand the printing options and find a clear way to request a quote.
- my contribution
- Built the Next.js page, interactive printer scene and service-to-quote flow, including Thai typography and mobile layouts.
- key decision
- Load the 3D scene separately, pause it outside the viewport and respect reduced motion so the illustration does not need to run continuously.
- result
- Visitors can compare materials, browse sample work and continue to LINE to request a quote from the same page.

Cafe’nMe
Tablet checkout using the repository’s demo café and orders. View full size screenshot of Cafe’nMe Next.js · TypeScript · NestJS · PostgreSQL · LINE LIFF
- hypothesis
- Café staff, owners and customers need different interfaces that share orders, menu data and loyalty rewards.
- my contribution
- Built checkout and menu-management flows alongside the API and LINE membership integration.
- key decision
- Keep the staff checkout, owner admin and customer member card distinct, while sharing the order and loyalty data behind them.
- result
- The implemented flow connects orders and payments to stamps and rewards, with sales reports for owners. The screenshot uses demo café data.

From pipette to pull request
I studied Biological Sciences at Mahidol University: titrations, microscopes, lab notebooks. In 2023 I traded the bench for a keyboard through an intensive bootcamp.
The method carried over. A bug is an unexpected result; a fix is a controlled experiment. Today I build product interfaces with React, Next.js and TypeScript, and work across Go APIs and Flutter apps when the product calls for it.
