What I work on

Engineering across the stack.

From the database layer to intelligent applications and market-data systems.

01

Backend Engineering

Production-oriented APIs and services with Python, FastAPI, SQLAlchemy, PostgreSQL, migrations, authentication, and modular architecture.

Backend systems →
02

AI & Machine Learning

AI applications, LLM integration, RAG, tool calling, local models, deep learning workflows, and model-driven products.

AI engineering →
03

Quantitative Systems

Market-data processing, TradingView/Pine Script systems, strategy research, backtesting, risk logic, and model integration.

Quant systems →

Engineering philosophy

Build the system, not just the feature.

01Architecture before abstraction
02Data integrity and security by design
03Automation where it removes operational friction
04Measure, test, iterate
