About Sai Teja — Backend & AI Engineer
I'm Sai Teja — a backend and AI engineer with 3+ years building distributed systems, enterprise platforms, and AI-powered products. I care about writing clean, efficient code and understanding the system end-to-end, not just the layer I own.
Currently at Dhan AI, I've shipped across customer portals, internal operations tooling, and a large-scale multi-tenant CXP platform. I'm drawn to hard problems — event-driven architectures, microservice coordination, and systems that need to be resilient at scale.
I'm equally deep into AI engineering — building with LLMs, RAG pipelines, and autonomous agents. I've worked with retrieval-augmented systems, prompt-engineered production workflows, and I actively track the frontier of open-source AI. For me, the most exciting work happens where backend systems meet AI — building the infrastructure that makes models useful in the real world.
Outside of work, I'm solving problems on LeetCode and posting about tech on Instagram — because explaining something well is how I know I actually get it.
Tech Stack & Skills
Projects
Customer Self-Service Portal
A customer-facing platform enabling users to view and manage active services in real time. Architected as a middleware microservice layer, bridging the frontend with multiple external service providers — handling auth, session management, and data orchestration.
Agent Operations Platform
Internal tooling for support agents to manage services and handle trouble tickets end-to-end. Built a proactive network diagnostics engine that detects and resolves infrastructure issues before customers are impacted — reducing dispatches and cutting resolution costs.
Enterprise CXP Platform
Modernized a large-scale customer experience platform with 15+ microservices powering onboarding, billing, payments, and order lifecycle. Delivered 30% improvement in API response times. Integrated Salesforce, Dynamics 365, and Firebase RBAC.
