About

Integration-focused Software Engineer with 2+ years of experience in building and maintaining enterprise-grade integrations using Workato. I specialize in designing scalable, API-driven, and webhook-based workflows, handling data transformations, and ensuring reliable communication between distributed systems. I have hands-on experience with recipe optimization, SQL collections, error handling, and production monitoring. I have successfully worked on integration migrations from Oracle SOA to Workato, redesigning pipelines for better scalability, performance, and maintainability. Alongside integration development, I actively build backend services using FastAPI, Node.js, and Spring Boot to strengthen my API design and system architecture skills. Open to opportunities in: • Integration Development (Workato / iPaaS) • API Integration / Middleware Engineering • Automation & Workflow Engineering Let’s connect!
