Backend engineer with 10+ years, now building production AI.
I bring a decade of designing scalable, high-availability distributed systems — and I’m channeling that same rigor into LLM-powered products, retrieval systems, and agentic AI.
About
Backend engineer, now building production AI.
I'm Maheswaren Manivannan, a Senior Software Engineer with 10+ years of backend experience, based in Berlin, Germany— now pivoting into AI Engineering. I've led the backend of a cloud-native rule engine platform for Athena One, a major US healthcare product, designing scalable, high-availability solutions serving over 20,000 customers at 99.9% uptime.
Today I'm channeling that same rigor into AI: building LLM-powered products, retrieval-augmented generation systems, and agentic workflows — grounded in Python, FastAPI, and AWS Bedrock, and deployed serverlessly with Terraform. This very site is one of them: a digital twin running on Lambda + Bedrock.
I've worked across cross-functional agile teams, consistently delivering high-quality, on-time results — recognized with multiple “Exceeding Expectations” appraisals and always eager for the next challenge in a collaborative, international environment.
How I work
- Professional but approachable
- Focused on practical, working solutions
- Clear, concise communication
- Backed by relevant real-world examples
