Who am I
I'm a frontend developer with 5+ years building web applications across the automotive, banking, consulting, and digital entertainment industries. I'm currently at Pixent, owning frontend delivery for a customer-facing gaming platform, after shipping enterprise banking products at Deloitte for Maybank.
I turn design mockups into responsive, accessible, high-performing interfaces with React, Next.js, TypeScript, and Tailwind, and I'm comfortable owning the full frontend lifecycle: from proof-of-concept to production, reusable component libraries, and REST API integration.
Beyond the UI, I set up the workflow around it — GA4/GTM analytics funnels, pre-render (SSG/ISR) for performance and SEO, and pre-commit and CI gates that keep quality high. I lean on Git and AI-assisted tooling like Claude Code to move fast without cutting corners.
I care about code quality, clear collaboration, and continuous improvement. If you're looking for a frontend developer who ships reliable UI and communicates well, let's talk.

What I've done
commit a4f1c9e
Frontend Developer
Pixent Technologies Sdn. Bhd.
December 2025 - Present
# Consumer Platform
+ Own frontend delivery across 4 applications — 2 consumer platforms, a partner portal, and a CMS — as 1 of 5 developers under a team lead
+ Building mini player and picture-in-picture playback for a new platform release, keeping sessions alive while users browse the catalogue
+ Drove the responsive implementation across desktop and mobile breakpoints and localised the interface for 3 languages
+ Partnered with the product designer to define a shared design system, then enforced it in code as a single token set for colour, buttons, and alerts
+ Reconciled inconsistencies in design handoff, flagging one-off colour values so components stayed on the system rather than drifting per screen
# Identity Verification (KYC)
+ Built the KYC verification module end to end, gating account features and fund movement behind a verified bank identity
+ Modelled the journey as a resumable 8-screen flow — verification status checked at the profile level, conditional mobile registration with OTP, bank detail submission, admin review, and a final amount challenge
+ Handled the asynchronous approval step, holding users in a pending state that survives reload and returns them to the correct stage on re-entry
+ Implemented the secondary verification challenge, matching the actual received amount against withdrawal plus additional funds, with attempt limiting and distinct success and failure terminal states
+ Designed an inline worked example alongside the challenge to reduce failed submissions on a step users only get a limited number of attempts at
# Web Performance & Analytics
+ Introduced the first analytics coverage on a platform that had none, scoping and implementing GA4 through GTM at the CTO's request
+ Defined the event schema for the full conversion funnel — homepage view, register click, signup completion, first deposit, session start and completion, reward redemption
+ Attached content identifier and session parameters to launch events so most-engaged titles and drop-off points become answerable questions
+ Authored a setup and handover guide so the incoming owner could migrate from my temporary test property to the company account
+ Applying pre-rendering (SSG / ISR) to marketing and landing pages to improve first paint and crawlability
# Engineering Workflow & AI-Assisted Development
+ Introduced a pre-push hook enforcing lint compliance locally, so issues are resolved before they ever reach the remote branch or CI
+ Extended the hook to generate currency icons from web3icons into public assets, covering all 5 supported currencies and closing a class of missing-asset bugs whenever a new one is added
+ Shipped the hooks as part of the repository, giving all 5 developers the same checks by default with no per-developer setup
+ Use Claude Code as a standing review step before every commit, and to reconcile upstream changes against in-flight work after pulling
# Partner Portal
+ Delivered the partner dashboard for referral tracking and performance reporting
+ Designed the data table, filtering, and export layer handling commission and campaign statistics
# Content Management System
+ Operate the CMS behind live campaigns, publishing promotional content to the consumer platform
+ Extended user records with KYC status filtering to support day-to-day operational checks
