I build web platforms that keep working as they grow.

The existing lecture video platform had become difficult to scale and maintain. Playback was inconsistent, analytics and logs became unreliable under load, and lecturers sometimes waited overnight before uploads were ready to stream.

I led the platform revamp with a modern React interface. I rebuilt the VOD pipeline, added resumable tus uploads, stabilized analytics, and introduced layered streaming controls using AES-128 and HMAC.

Community finance groups needed a more reliable way to manage members, loans, payments, and identity checks. Paper ledgers made balances difficult to verify, while member identity at the counter depended on manual recognition.

I designed and shipped a Next.js admin dashboard, an Electron scanning station, Supabase Realtime, and a C# bridge for encrypted fingerprint verification. I used a spec-driven AI workflow to add a statistics page, fines, and member benefits after the build was underway. The production MVP shipped in six weeks.

A multi-branch institution was managing finance, alms schedules, donor pledges, and branch records across paper logbooks. Visitors also relied on printed signs or staff explanations to find information on site.

I built a bilingual, multi-tenant Next.js platform on Supabase with strict row-level security and role-based institution access. Beyond administration, finance, alms, and a per-institution QR visitor guide, it runs an automated pledge engine that tracks long-running donor commitments across partial payments with monthly SMS reminders on a cron.

A two-sided cleaning service platform needed to ship booking and operations flows to early users while reducing frontend instability and post-release defects.

I owned the React frontend architecture, clarified state and data boundaries, and added Vitest and Playwright coverage around critical flows. I worked with backend and product teammates to stabilize the pilot for 50+ early adopters.

A family wholesale business lost all retail orders overnight when COVID-19 shut down brick-and-mortar shops. The operation had no online presence, no brand identity, and no direct-to-consumer channel.

I created the consumer brand, built the WordPress storefront and Daraz seller presence, photographed the catalogue, ran SEO and social campaigns, and managed the product-to-delivery workflow.
