About Me

Jaron Harness, a Software Developer

I’m a backend‑focused Python developer who enjoys building clean, reliable APIs and solving real engineering problems. My current work centers around FastAPI, PostgreSQL, SQLAlchemy, Alembic, and Docker, with an emphasis on maintainability, clarity, and modern backend design.

I earned my B.S. in Software Engineering from WGU and hold certifications in ITIL, AWS Cloud Practitioner, and Project+. Before shifting into Python, I developed applications in C#/.NET, completing Claim Academy’s full‑stack program — experience that still strengthens my architectural thinking and problem‑solving today.

My Skills

As a backend-focused Python developer, I’ve built my expertise around designing reliable APIs, robust data layers, and containerized services. My skills span backend architecture, database design, migrations, validation, and deployment with tools like FastAPI, SQLAlchemy, PostgreSQL, Alembic, Docker, and Docker Compose.

Python Backend Development

I build maintainable backend services and APIs in Python, with a focus on clarity, reliability, and modern application design.

FastAPI Design & Development

I design RESTful endpoints and data contracts that are easy to consume, document, and evolve as product needs change.

Database & ORM Development

I work with SQLAlchemy and relational data models to build efficient, maintainable persistence layers for applications.

PostgreSQL & Alembic

I use PostgreSQL for reliable data storage and Alembic for structured schema evolution and migration management.

Docker & Containerization

I use Docker and Docker Compose to package applications, simplify local development, and support consistent deployments.

Testing & Validation

I value clear validation, strong typing, and reliable testing practices to build backend systems that are easier to maintain and extend.

My Projects

I build modern backend systems with a strong focus on Python, FastAPI, and PostgreSQL. My projects emphasize clean architecture, maintainability, and real‑world engineering practices. While Python is my primary focus, my background in C#/.NET remains a valuable secondary strength that enhances my versatility and problem‑solving approach.
