I’m Apurba Sarkar, a full-stack software developer with 3+ years of hands-on experience building fast, secure, production-ready web applications using JavaScript and TypeScript, backed by scalable, maintainable architectures.
I focus on clean system design, performance, and security, delivering authentication systems, dashboards, internal tools, and database-driven applications built for long-term maintainability and growth.
Alongside product development, I specialize in Zoho CRM automation, designing workflows, integrations, pipelines, and Deluge functions that reduce manual work, eliminate errors, and improve operational efficiency.
I hold a Master of Computer Applications (MCA) degree, with a strong foundation in software engineering, databases, and system design. I’ve worked with clients across Canada, the United States, and India, and I’m open to remote roles and selective projects.
