Software Engineer | Functional Programming Specialist | Clojure
"Finding simplicity in complexity through functional programming and clean architecture."
Focused on backend mastery and evolving towards Tech Leadership:
- Backend Systems: High-concurrency services with Clojure, distributed architectures, event-driven design
- GenAI Engineering: Production-ready AI backends with Python, LangChain, and RAG
- Modern Fullstack: TypeScript/React with strongly-typed contracts
- Architecture Excellence: Clean Architecture, DDD, Hexagonal patterns
- Leadership Growth: Mentorship, design reviews, cross-team alignment
This journey reflects my commitment to backend mastery and leadership—where engineering excellence meets pragmatic delivery.

Backend Engineering | Distributed Systems | Clean Architecture & DDD | GenAI Integration
My current exploration is focused on pushing the boundaries of backend engineering:
from building highly concurrent systems in Clojure/Python, to integrating GenAI into production backends with Python,
to exploring modern fullstack experiences with ClojureScript.
This path is guiding me toward becoming not just a strong individual contributor, but a future Tech Lead who can drive architecture, mentor teams, and deliver business-critical systems at scale.
