I have 5.5 years of experience as a full-stack engineer, mainly working on SaaS, IoT, and cloud-based platforms. In my previous role as a Senior Software Engineer at Crest Data. I built and improved backend services for a large energy SaaS platform used for EV, HVAC, solar, battery, and utility system integrations. I worked with Python, Flask, Node.js, Docker, AWS, PostgreSQL, MongoDB, Redis, REST APIs, webhooks, MQTT, WebSocket, and microservices architecture. My work included building scalable APIs, async backend services, third-party integrations, automation tools, encryption/decryption modules, and real-time data workflows. Key achievements: Contributed to product features that helped increase product-driven sales by around 80%. Led a team of 4 engineers to improve backend quality and delivery. Designed and implemented microservices for better scalability and maintainability. Integrated multiple device and manufacturer systems using REST, MQTT, WebSocket, OCPP, and Modbus. Improved backend reliability, performance, and security across distributed services. Worked on OWASP-based security testing and backend best practices. I can help clients build reliable APIs, backend systems, dashboards, automation tools, third-party integrations, and cloud-based applications with clean, maintainable code.
