Building applications that solve real problems

About MeAbout Me

Full-stack developer who bridges web applications and ERP systems — building custom solutions on ERPNext and Frappe Framework while delivering modern frontends with Vue 3, SvelteKit, and Next.js. Comfortable across the stack from back-end APIs with Spring Boot, Express, and Nest.js to database design with MariaDB, PostgreSQL, and MongoDB.

I enjoy automating complex workflows, integrating distributed systems, and turning manual business processes into scalable digital pipelines. Currently open to opportunities where I can build impactful software and grow alongside a strong engineering team.
