What I'm looking for

I’m looking for a role where I can build resilient back-end systems and user-friendly front ends, lead integrations, and apply ML to real problems—working in a team that values scalable architecture, performance optimization, and modern cloud/dev practices.

I’m a Senior Software Engineer with 8+ years of hands-on experience, focused on designing and building resilient back-end systems and user-friendly front-end applications. I lead high-impact integrations, architect scalable solutions, and deliver measurable performance improvements, especially when reliability and speed both matter.

In my current role at LCvista, I spearheaded the architecture and end-to-end implementation of a LinkedIn Learning integration for an in-demand LMS feature that syncs course catalogs and tracks completions via xAPI. I also migrated a recently acquired application from PHP to Python using a side-by-side approach, implemented smart report generation with background processing and email delivery, and supported DevOps efforts to deliver robust infrastructure across PostgreSQL, MySQL, and MSSQL.

Previously, at Tagshelf, I led document processing and chatbot/omni-channel initiatives with real social impact—implementing ML workflows for vaccine-related documents during the COVID-19 pandemic, and cutting manual document processing effort by 40% for a leading insurance company using cloud-native tooling. I’ve also mentored newly graduated engineers, translated customer needs into clear technical requirements, and improved delivery speed through automated deployments, containerization, and SDK-driven development, backed by AWS Machine Learning and AI practitioner certifications.
