About

Backend Engineer with 6+ years of professional experience building scalable, reliable, and high-performance backend systems across finance, healthcare, and e-commerce domains. I specialize in Java and Python backend ecosystems, with hands-on experience in Spring Boot, Django, Flask and Fast API, designing RESTful APIs, microservices, and distributed systems. Strong background in System Design (HLD/LLD), database design, and clean architecture, enabling effective translation of business requirements into robust technical solutions. Experienced in working with SQL and NoSQL databases (MySQL, PostgreSQL, Redis, MongoDB, DynamoDB, Elasticsearch) and building cloud-native applications on AWS/Azure. Comfortable with event-driven architectures, Kafka, and containerized deployments using Docker and Kubernetes. I emphasize engineering excellence through SOLID principles, design patterns, TDD, observability, and performance optimization and thrive in agile, fast-paced environments while collaborating with cross-functional teams to deliver impactful solutions. I'm always open to new challenges and exciting opportunities. Please feel free to connect or reach out at ronakgoti2020@gmail.com
