I've built cloud-native microservices, REST and GraphQL APIs, and full-stack products across healthcare, conversational AI, and enterprise SaaS for Zemoso Technologies, Cloud4C, Apollo 24|7, and Sayint.ai.
At Zemoso Technologies, I developed Measurement Mode for cell-structure image analysis and built a customizable cell tagging and annotation system using React.js and Express.js. I also improved bulk ingestion throughput by implementing PostgreSQL COPY.
At Cloud4C, I architected a workflow engine that generated Apache Airflow DAGs from JSON payloads through RabbitMQ, and built Elasticsearch-powered ITSM search and a payment application with monitoring and automated alerts. I also developed a document-verification orchestrator using Azure Durable Functions and Cognitive Services.
At Apollo 24|7 and Sayint.ai, I delivered geo-search, serverless IVR reminders, distributed appointment locking, deployment automation, and Prometheus-based monitoring. I focus on system design, performance optimization, and reliable delivery with Node.js, TypeScript, React.js, PostgreSQL, and cloud-native tooling.
