BRYAN MEJIA
From computer science principles to agentic systems in production.
My path through software engineering has been additive. Each layer I learned became the foundation for the next, and all of it now points toward AI.
Computer Science Principles
It started at CUNY Queens College: data structures, algorithms, operating systems, and the habit of reasoning about a problem before reaching for a keyboard. That grounding is still the part I lean on most.
Software Engineering
I learned how systems are built and maintained, not just designed. Java and C++ taught me structure, JavaScript and TypeScript taught me the web, and shipping to real users taught me the difference between working and reliable.
Data Science and Machine Learning
Working with Pandas, NumPy and model pipelines shifted how I think about problems, from deterministic logic toward evidence, evaluation and uncertainty.
AI and Agentic Systems
This is where I work today: agent harness integration, lifecycle-hook context injection, tool calling, RAG, and the cloud infrastructure and cost engineering that keep it all running in production.
