What I'm looking for

I seek a role where I can build reliable full-stack systems, work with cross-functional teams in Agile, and contribute to scalable cloud deployments.

I am a software engineer with extensive experience building web and mobile systems across frontend, backend, APIs, databases, and cloud infrastructure.

I have developed and maintained internal banking and enterprise applications, public-facing e-commerce platforms, and classified marketplaces, contributing to APIs, frontend modules, performance tuning, and integrations with POS and enterprise systems.

My work highlights include designing secure RESTful APIs, implementing Redis caching to improve performance, contributing to large-scale retail and telecom platforms, and supporting deployments on AWS and CI/CD pipelines.

I collaborate closely with product, QA, and operations teams in Agile/Scrum environments and bring a practical, results-focused approach to delivering reliable, maintainable systems.
