About Me
Hello! I'm Rachit Tyagi, a Senior Full Stack Engineer with over 12 years of experience building mission-critical software. I don't just write code; I design systems that are scalable, predictable, and built to last.
My expertise lies in bridging the gap between complex backend architectures and intuitive frontend experiences. Recently, my focus has shifted towards Agentic AI—moving beyond simple chatbots to create reliable, reasoning systems that can safely execute real-world tasks.
Whether operating as a Tech Lead or an Architect, I prioritize clarity, clean code, and making pragmatic engineering trade-offs.
Specializing in controlled reasoning systems, schema-first validation, and deterministic tool use—ensuring LLMs are powerful yet safe.
Designing API-first platforms and microservices that scale. Expertise in distributed systems, cloud infrastructure (AWS/Azure), and DevOps.
From mentoring junior engineers to driving technical strategy, I foster a culture of excellence and long-term maintainability.
