Backend is wherethe building really starts.

I build server-side systems with the discipline of someone who draws the architecture first. My work at Planeta IP Comunicaciones SAS ESP centers on C# / ASP.NET services backed by PostgreSQL and Dapper, with RBAC and JWT auth, structured around Clean Architecture boundaries. I treat AI-assisted workflows — Claude Code, Codex — as first-class engineering tools: faster iteration, but the review standard stays human.

    Planeta IP Comunicaciones SAS ESP

    • End-to-end backend ownership: PostgreSQL schema design and migrations, API development, integrations, and production readiness.
    • Implemented a versioned ASP.NET Core REST API with exception middleware, response standardization, and rate limiting.
    • Built cookie-based JWT auth with refresh-token rotation and hashing, plus RBAC with hierarchical policies.
    • Performance-focused data layer with Dapper (parameterized SQL, paging/search, CTE reporting) and transactional workflows via Unit of Work.
    • Refactored PostgreSQL stored functions from hardcoded implementations to dynamic, parameterized versions with layered validation for an emergency-management system.
    • Integrated AI-assisted development workflows (Claude Code, Codex) into daily engineering: architecture planning, code review, and PostgreSQL function design.

003MethodHow I work

Three commitments I won't trade.

01

Drawings first

Domain and use-case diagrams precede code. Clean Architecture contracts keep boundaries honest so the codebase stays tractable as it grows.

02

AI-paired, human-reviewed

Claude Code and Codex act as accelerators and first reviewers. Every diff still passes a manual read and the test gate before it merges.

03

Proof by tests

Vitest and Playwright on the web surface; xUnit patterns on backend work. If it matters enough to ship, it matters enough to pin down with a test.
