Cover image for The goal of this project
The goal of this project was to design and develop a user-friendly digital platform that simplifies the ketogenic lifestyle and makes it accessible for beginners while delivering real, measurable health results. I worked on crafting a conversion-focused experience that translates complex nutritional science into an intuitive, easy-to-follow journey. The platform guides users from onboarding to goal achievement through personalized plans, smart tracking, and continuous support. The solution includes a structured onboarding quiz, tailored meal plans, progress tracking, and educational content designed to help users adopt and sustain the keto lifestyle with confidence. Special focus was placed on personalization, usability, and motivation to ensure long-term engagement. The result is a scalable, high-engagement platform that empowers users to lose weight, improve overall health, and build sustainable habits—supported by data-driven insights and a strong community-driven approach.

Cover image for Wikifarmer needed a scalable, trust-driven
Wikifarmer needed a scalable, trust-driven digital platform to connect thousands of agricultural suppliers with large global buyers — eliminating the inefficiencies, price volatility, and quality uncertainty that plague traditional supply chains. I contributed to the end-to-end design and development of the platform, integrating AI-powered features to enhance sourcing intelligence — including smart supplier matching, dynamic pricing insights, and automated quality assurance workflows. The platform covers the full supply chain lifecycle: from harvest and packing to shipping, logistics, and final delivery. Key features built include a multi-category product marketplace (olive oil, fruits, vegetables), a 360° logistics management system, AI-assisted buyer-supplier negotiation tools, and a transparent transaction layer ensuring security and accountability for every order. The result is a high-performing B2B marketplace that has revolutionized agricultural sourcing for buyers and producers across Europe and beyond — reducing procurement costs, improving cash flow with net-30 financing, and delivering measurable gains in supply chain efficiency and product quality.

Cover image for A full-featured e-commerce platform built
A full-featured e-commerce platform built for one of Hong Kong's most trusted pet stores — bridging the gap between a beloved local shop and a scalable online retail experience. The platform needed to handle a large product catalog, multiple service offerings, and a loyal customer base, all within a seamless and intuitive shopping experience. Built on Shopify with heavy customization to support the complexity of a multi-category pet care ecosystem — from frozen raw food to vet diet products and in-store service bookings. What Was Built → Custom Shopify storefront with tailored UI components across hundreds of product listings → Advanced product filtering and categorization system for dogs, cats, healthcare, and brands → Subscription and save flow integrated for repeat purchase products with automated billing → VIPaws loyalty membership system with tiered rewards and member-exclusive pricing → Product bundling and gift subscription features for promotional campaigns → Multi-location store finder integrated with opening hours and service details → Service booking integration for grooming, self-dog wash, and café reservations → Performance-optimized pages with fast load times across large catalog pages → Mobile-first responsive design for on-the-go pet owners

Cover image for A clean, modern website built
A clean, modern website built for a dental clinic in Edmonton, Canada. The goal was to create a digital presence that feels as comfortable and trustworthy as walking into the clinic itself — turning first-time visitors into booked appointments through thoughtful design and a clear user journey. Dental websites often fall into two traps — either too clinical and cold, or too generic and forgettable. This one was built to avoid both. Every design decision, from the color palette to the page structure, was made with one goal in mind: make the visitor feel at ease and make it effortless to take the next step. The Build The site was architected as a multi-page experience covering everything a new patient needs before their first visit — services, team introductions, office details, reviews, and an easy path to book. The information hierarchy was carefully planned so that nothing feels overwhelming, and every page naturally guides the user toward conversion Special attention was given to mobile performance, since a large portion of local service searches happen on mobile. The responsive layout adapts cleanly across all screen sizes without losing the visual quality of the desktop experience. The blog and reviews sections were built with long-term growth in mind — giving the clinic a platform to publish patient education content and collect social proof over time, both of which contribute to local SEO and ongoing trust-building. What Was Built → Fully responsive multi-page website optimized across all devices → Conversion-focused layout with clear appointment booking flow → Services page structured to educate and reassure new patients → Blog section for patient education and ongoing SEO content

Cover image for Baccarat — real-time multiplayer card
Baccarat — real-time multiplayer card game: An online Baccarat table where players bet, deal and settle in real time, together. Multiple players sit at the same table and watch the same round unfold at the same instant, so every client has to stay in sync to the card. A server-authoritative game loop runs the round — betting window, deal, third-card rule, settlement — and pushes state over WebSockets, which means no client can influence the outcome. The shoe is shuffled with a cryptographically secure RNG and every round is recorded, so any hand can be replayed and verified after the fact. **Built** - Player / Banker / Tie betting with per-round bet windows and limits - Real-time multiplayer tables synchronised over WebSockets - Server-authoritative game loop implementing full Baccarat drawing rules - Cryptographically secure RNG shuffle with a verifiable, replayable round log - Automatic settlement, payout and per-player hand history

Cover image for A central authorization service that
A central authorization service that decides who can do what — in real time: Instead of permission checks scattered through every service, one engine answers a single question: given this user, this action and this resource, ALLOW or DENY? Policies combine roles (RBAC) with attributes (ABAC) — department, ownership, region, time of day — so product teams change a policy instead of shipping code. Every decision is logged, which is what auditors actually ask for. Built - Role-based and attribute-based policy evaluation - Low-latency decision API with policy caching - Policy authoring and versioning, so changes are reviewable and reversible - Immutable audit log of every allow/deny decision

Cover image for An e-commerce storefront for buying,
An e-commerce storefront for buying, gifting and redeeming digital gift cards. Customers pick a card and an amount, pay through a secure checkout, and the recipient gets the card by email within seconds. Behind it sits the part that actually matters: a balance ledger that stays correct under concurrent redemptions, idempotent payment handling so a retried request never double-charges, and a full audit trail of every issue and redemption. Built - Card catalogue, custom amounts and gift-to-a-friend flow - Payment gateway integration with idempotent, retry-safe order handling - Email delivery pipeline for instant card issuance - Balance, partial redemption and expiry logic backed by a transactional ledger

Cover image for A healthcare booking platform connecting
A healthcare booking platform connecting patients with the right doctor: Patients search by speciality, see genuinely live availability, and book a slot in a few taps. The hard part is concurrency: two patients tapping the same 10:30 slot at the same moment must not both get it. Slot locking and transactional booking make that safe, and reminders cut no-shows. Built - Doctor search and profiles with speciality and location filters - Real-time slot availability with race-safe booking and cancellation - Appointment lifecycle: book, reschedule, cancel, remind - Patient records with role-based access, so staff see only what they should

Cover image for Legacy HRMS Assessment Module I worked
Legacy HRMS Assessment Module I worked on a legacy 25-year-old HRMS system originally built in PHP. My main focus was the assessment module, where questionnaires created by psychologists were used to evaluate employees for company culture fit and personality through two separate assessments. It was a challenging but very informative project that taught me a lot about working with complex legacy systems and business logic. Best part: Learning that the client’s developer had written code directly in the database because there was no frontend support to execute it on the client side.

Cover image for I just finished my new
I just finished my new personal hero page. The part I'm most excited about is the 3D character. As you scroll, it plays out frame by frame, so you're basically controlling the animation with your scroll wheel. It also reacts to your mouse, which makes the page feel alive the moment you land on it. What I focused on: - A 3D character that moves as you scroll - A clean black and white look with nothing extra on the page - Plus Jakarta Sans for the main text, with a cursive font for a personal touch - Small pill buttons like Pitch us an idea and Loved your work. - One click to copy my email Built with React, TypeScript, Vite, Tailwind CSS and Lucide icons. The character animation runs as a frame sequence drawn on canvas. I dont think a personal website should be a static resume. It should show your taste and your craft before anyone reads a word about you. I build WordPress and WooCommerce sites for clients too, with a team of developers and designers behind me. If you have a project in mind, lets talk. Have a look and tell me what you think. And if you're building something interesting right now, Id love to hear about it.
