I’m a systematic, detail-oriented Backend Engineer with an Associate Degree in Computer Science, specializing in data-driven architectures. I build high-performance RESTful APIs and optimize complex SQL databases while debugging imperfect real-world datasets.

In my IT & Data Management Intern role, I audited and validated system and web records to catch logic anomalies and protect data integrity constraints. I also cleaned and refactored structured data layouts, improving processing pipeline efficiency by 20% under senior guidance.

As the Core Developer / Backend Lead on Pintuplomer, I implemented a decoupled modular monolith backend with Flask, enforcing clean code conventions and SOLID principles. I structured a PostgreSQL schema layer with raw optimized queries and explicit connection pooling (psycopg2) for sub-second execution.

I’m also committed to secure, maintainable systems—engineering server-side exception handlers, Argon2 password hashing, and JWT refresh token rotation. I leverage Gemini AI with structured prompting to accelerate refactoring and support project-based learning inside agile teams.
