About

Senior Backend Engineer passionate about building intelligent, scalable systems at the intersection of Python, AI/ML, and cloud infrastructure. At Entropik Technologies, I've grown from intern to Senior Software Engineer, engineering backend services that power real-time AI/ML features. From designing data pipelines with the Data Engineering team to deploying NLP-driven APIs using FastAPI and Celery, I've integrated platforms like Microsoft Teams, Figma, ElevenLabs, and 100ms to bring AI-powered communication and collaboration features to life. My work spans the full backend lifecycle: architecture, async processing, performance tuning, and production reliability. Earlier at Cognizant, I automated insurance workflows using Python (cutting manual effort by 40%), wrote complex SQL on DB2, and collaborated with DevOps teams on Infrastructure as Code, giving me a strong foundation in enterprise-scale systems. What I bring to the table: FastAPI and Python-based backend development for high-performance REST APIs. AWS cloud architecture using Lambda, EC2, S3, and DynamoDB with hands-on Boto3 automation. Containerized deployments with Docker ensuring consistency across dev, staging, and production environments. Async task processing with Celery for scalable background job handling. CI/CD pipeline implementation via Jenkins and microservices architecture design. NLP integration and AI/ML-enabled backend services in production. I'm drawn to teams solving hard, meaningful problems, especially in AI infrastructure, developer tools, NLP, or data-heavy SaaS products. I care about clean code, system reliability, and shipping things that actually matter. 🛠️ Tech Stack: Python · FastAPI · AWS (Lambda, EC2, S3, DynamoDB) · Docker · Celery · REST API · Boto3 · SQL · NLP · Microservices · CI/CD · Jenkins · Azure · Git 🎓 MCA – Bharathiyar University | BSc – Kongu Engineering College 📬 Open to Senior Backend and FastAPI Developer roles · sibisengodan@gmail.com
