Projects

A multi-tenant cash-on-delivery order-form and upsell application, live on the Shopify App Store and serving merchant storefronts in 9 languages. I owned it end to end: tenant onboarding, a drag-and-drop configuration builder and template system, the offer engine with per-product and collection-level targeting, order analytics, multi-pixel event tracking, and localisation.

A subscription SaaS product for abandoned-cart recovery, live on the Shopify App Store with a 5★ customer rating. I led delivery from design to production — subscription billing with a free-trial flow, tenant provisioning, and a queue-based webhook pipeline with idempotency guarantees that sustained all inbound traffic with zero data loss.

An end-to-end returns workflow spanning RMA, refunds and restocking. The hard part was not the UI: it was translating wildly varied customer return policies into configurable business rules and the schemas that support them, so a merchant could express their own policy without a code change.

A lead-capture platform shipped end to end with Next.js and Express, using Puppeteer for automated data collection. I built both the backend architecture and the dashboard UI.

A commercial digital publishing platform with a global user base that converts PDFs into interactive flipbooks. I delivered production features inside an established codebase and release process, and maintained Jest / React Testing Library coverage on critical user flows.

An AI-powered podcast creation platform with script generation, voice cloning and multi-voice narration. I built the full frontend, including a custom audio player, and integrated the LLM and text-to-speech APIs.

Serverless ingestion of 50+ Bangladeshi and international news sources on a scheduled function pipeline, storing normalised feed data in MongoDB behind a Nuxt.js frontend.
