Karthikeyan Govindarajan

At ABOTTS Consulting Inc., I built and maintained FastAPI REST APIs, modular backend services, and Dockerized microservices that reliably handled 1,000+ daily requests. I improved median API response time by about 25% through asynchronous request handling and PostgreSQL query optimization.

I've integrated third-party services with HTTPX and Requests, adding retries, timeouts, and resilient error handling to achieve 99%+ service availability. I take backend features from development and testing through deployment, production debugging, and continuous improvement.

I also built a real-time outbound EMI reminder voicebot using FastAPI, WebSockets, Deepgram, Google Gemini, and ElevenLabs, with streaming audio, interruption handling, and payment-intent workflows. My projects include insurance-processing APIs, a multilingual Tamil–Telugu speech translation system, and full-stack airline and service-management platforms.

I'm grounded in Python, Java, React.js, PostgreSQL, Docker, distributed systems, and machine learning workflows. I enjoy solving performance and reliability problems while building maintainable software products.
