I build web applications, browser extensions, AI-enabled tools, automation systems, and developer utilities.
My current focus is Next.js, React, TypeScript, PostgreSQL/Prisma, AI-assisted development, QA, product engineering, and deployment workflows.
I bring 7+ years of additional professional experience across technical SEO, analytics, digital products, web operations, troubleshooting, and client delivery. That background influences how I approach development: I think about the code, the user, the data, performance, discoverability, testing, and business impact together.
Based in Bangladesh. Open to paid remote internships, junior developer roles, and international product teams.
