Enterprise systems, built to scale

Turning business requirements into reliable software — from application architecture through to the modules people use every day.

I'm a Senior Software Engineer at NIIT Limited, working on the design and development of an internal enterprise CRM platform similar to Salesforce — built to support complex business processes, customer relationship management, sales operations, workflows and organizational collaboration.

I specialize in building scalable, secure and high-performance web applications and RESTful APIs, with experience across both backend and frontend development. My work involves designing application architecture, developing business-critical modules, integrating services, optimizing databases and search systems, and delivering maintainable enterprise solutions.

I enjoy solving complex engineering problems, turning business requirements into reliable software, and building systems that scale with organizational needs. I'm particularly interested in enterprise application architecture, distributed systems, API design, performance optimization and modern web technologies.

My goal is to continuously improve as an engineer while contributing to products that create measurable business value through technology, automation and scalable software architecture.
