Hi, my name is
David Camilo Cortes Salazar
Software Engineer
Bogotá D.C., Colombia
Software Engineer with experience in full-stack development, automation of high-volume manual operational processes, and software architecture design oriented toward extensibility.
I care about design that survives change: extensible architectures, clear boundaries between modules, and technical decisions another developer can pick up without rebuilding the context from scratch.
Experience
Oct 2025 – PresentCurrent
Software Engineer · Evolution Consulting SAS
Bogotá D.C., CO
- Sole technical point of contact for 5 active client companies (3 more onboarding) for the "Autoservicio" portal (PHP/Laravel monolith).
- Built end-to-end the vacation, payroll-period and authorizer module, in active production across 4 client companies.
- Designed a Spring Boot microservice around the Strategy pattern so new payroll change types (paid/enjoyed vacations, disability leave by type) plug in without touching existing code (Open/Closed).
- Cut duplicate historical records by ~99.5% (from ~50,000 to 200-300 per company) with parameterized, reusable SQL Server queries across 6 client companies.
- Automated the generation of external Excel formats with a cross-platform desktop application (React + Tauri, Python backend), eliminating that manual work.
- Led requirements mapping, user stories, sprint estimation and PR reviews for the module across 4 client companies.
