Pisitkorn Bootchada

Building and maintaining the e-commerce frontend end to end: a 3D PC builder, Omise saved-card payments, AWS deployment, SEO monitoring and the ERP Prototype V1 frontend, all wired to REST APIs for product data and the cart. Started alongside a senior backend developer and moved into a dedicated frontend role after showing strength in web development.

Developed a “Ship To” shipping submission page with ASP.NET Core MVC and an e-mail notification triggered on save.

Built a weather forecast website and an air quality index monitor for the factory: React front end, Node.js back end and Arduino sensor hardware.

3D PC Builder · iHAVECPU

• Real-time 3D scene that colours each part from the selected product, with selection effects and spec callouts
• A 7-slot bar for the main parts, plus a dock and product panel for picking
• Filters products by socket and slot; RAM, M.2 and GPU picks auto-adjust when the motherboard changes, with an undo notice

Checkout & Payments · iHAVECPU

• Coupon and monthly-instalment calculations at checkout
• Address and tax-invoice validation so orders go out right the first time
• Saved cards on Omise: looks up an existing customer by e-mail first, so no duplicates

Site-wide Dark Mode · iHAVECPU

• Design tokens in CSS variables so both themes come from one source
• Light theme kept pixel-identical while dark mode was added
• Theme toggle animated with the View Transitions API

Storefront UX · iHAVECPU

• Product Journey: recommends products by what you'll use them for, with purpose selection, a guideline and an interview overlay, plus a mobile journey
• Benchmark product cards that show expected game performance for the spec, with skeleton loading
• Redesigned image zoom: a rotary dial outside the image on wide screens and a zoom bar on tablets, applying transforms directly while dragging to cut re-renders
