Sagar Neeli

Senior Backend Engineer

Building scalable, intelligent systems with ~10 years of experience in backend engineering, distributed architectures, cloud engineering, and cutting-edge AI/ML solutions.

About Me

I'm a Senior Backend & AI Engineer with a passion for building intelligent, scalable systems that solve real-world problems. With nearly a decade of experience, I've evolved from a traditional backend engineer to a specialist in AI-powered solutions and distributed architectures. My brand is expressed through a minimalist SN monogram—clean, future-focused, and unmistakably mine.

AI/ML Engineering

Building intelligent systems with modern AI/ML technologies including LLMs, RAG pipelines, and vector databases.

Backend Development

Scalable microservices, APIs, and distributed systems using Python, Java, Go, and modern frameworks.

Cloud Architecture

AWS, GCP expertise with containerization, Kubernetes orchestration, and infrastructure as code.

Data Engineering

Building robust data pipelines, ETL processes, and analytics platforms with modern data stack.

Performance Optimization

High-performance systems optimization, caching strategies, and real-time processing pipelines.

System Design

Architecting scalable, fault-tolerant systems with event-driven architectures and message queues.

My Journey

From Backend to AI Engineering

My career began with traditional backend development, building APIs and microservices. Over time, I've increasingly focused on integrating AI/ML capabilities into production systems, from simple automation to complex generative AI applications.

Scaling AI in Production

At HubSpot, I led the integration of AI translation services that achieved 95% adoption across 30+ languages. This experience taught me the challenges of deploying AI at scale and the importance of building robust, user-friendly AI systems.

Future-Focused Innovation

I'm passionate about the intersection of AI and backend engineering, particularly in building agentic systems, RAG pipelines, and intelligent automation. I believe the future lies in systems that can think, learn, and adapt autonomously.

Experience

A decade of building and scaling intelligent systems across various industries and technologies.
