Experience

Enterprise AI Healthcare Platform

I led the development of an enterprise healthcare platform that transformed complex, manual workflows into intelligent AI-assisted experiences for clinicians and operational teams. The platform combined modern full-stack engineering with Generative AI to analyze medical documents, automate workflows, and surface relevant information through semantic search and Retrieval-Augmented Generation (RAG).

I was responsible for the solution architecture, front-end and back-end development, cloud infrastructure, and AI integration. Working closely with product leaders and engineering teams, I designed scalable React and Node.js applications, built secure APIs, implemented LLM-powered workflows, and optimized the platform for enterprise-scale performance and reliability. The result was a production-ready AI platform that improved workflow efficiency, reduced manual effort, and established a scalable foundation for future AI capabilities.

AI Agent & Intelligent Automation Platform

Designed and developed an enterprise AI platform that enables organizations to automate document understanding, knowledge retrieval, and business workflows using Large Language Models and intelligent AI agents. The solution integrated Retrieval-Augmented Generation (RAG), semantic search, and multi-step AI orchestration to deliver accurate, context-aware responses across large enterprise knowledge bases.

I led the platform architecture and implementation, integrating OpenAI and Claude models into production-ready services while designing scalable back-end APIs, evaluation workflows, and cloud-native infrastructure. The project significantly reduced manual knowledge retrieval and accelerated business decision-making through intelligent automation.

ReportWell Compliance & Workflow Platform

Developed a cloud-native compliance and workflow management platform that streamlined documentation, approvals, and reporting for educational organizations. The platform replaced manual processes with configurable digital workflows, improving operational efficiency while supporting multiple stakeholder groups.

I designed the core front-end and back-end architecture, developed secure APIs, implemented role-based access control, and optimized reporting for large datasets. The solution delivered a scalable SaaS platform that simplified compliance management and reduced administrative overhead.

Enterprise SaaS Platform

Architected and developed a modern SaaS platform supporting enterprise customers through secure authentication, scalable APIs, operational dashboards, and workflow automation. The project emphasized maintainability, performance, and scalability while supporting continuous product growth.

I owned the technical architecture across front end, back end, database design, and deployment automation, collaborating closely with product teams to deliver production-ready software that scaled with customer demand.

Real-time Collaboration Platform

Built a real-time collaboration platform enabling teams to communicate, synchronize data, and collaborate through live updates across distributed environments. The project required highly responsive user interfaces and a reliable real-time communication architecture.

I designed scalable back-end services, implemented WebSocket-based communication, optimized application performance, and delivered responsive front-end experiences capable of handling concurrent users with low latency.

Cloud Modernization & Platform Engineering

Modernized legacy enterprise applications by migrating monolithic systems to scalable cloud-native architectures while improving reliability, deployment automation, and operational performance. The initiative introduced modern engineering practices and cloud infrastructure to support long-term product evolution.

I led architecture planning, cloud migration, deployment automation, and back-end modernization while establishing reusable engineering standards and CI/CD pipelines that significantly improved delivery efficiency and platform scalability.
