Melbourne 🇦🇺 → Dhaka 🇧🇩

I'm a Software Engineer with 4+ years of experience building production web, mobile, kiosk, and backend applications.

Most recently I worked at Redcat, where I built customer-facing software used by 300+ hospitality brands across Australia and the UK, shipping features across React, React Native, TypeScript, Python, and PostgreSQL.

I enjoy solving complex engineering problems, designing maintainable systems, and owning features from product discovery through production deployment.

Lately I've been building AI-powered applications, experimenting with semantic search, vector embeddings, LLM integrations, and developer tooling.

• Built and shipped production features across web, mobile, kiosk, and internal dashboard applications.
• Delivered customer-facing software supporting 300+ hospitality brands.
• Led the integration of a new payment provider across React and React Native applications.
• Built backend APIs using Python and PostgreSQL.
• Refactored legacy systems, improved maintainability, and resolved production issues.
• Worked closely with product managers, designers, QA engineers, and external partners.
