Hector

Hello! I'm Héctor, a Software Engineer focused on designing and building robust, maintainable, business-oriented solutions.

I specialize in building services and platforms on scalable, resilient, and observable infrastructures, applying architecture best practices, quality standards, and continuous delivery.

I also leverage AI throughout the development lifecycle to improve efficiency in implementation, code auditing, refactoring, and software project modernization.

I combine hands-on technical execution with project management to turn functional needs into real solutions: from analysis and design to deployment, operations, and continuous improvement.

On this site you'll find my experience, technologies, and projects. If you're looking for a technical profile with a holistic view of product, architecture, and delivery, let's connect. LinkedIn

Senior .NET Software Engineer: application and platform architecture, AWS and AI agents

Senior .NET Software Engineer focused on application and platform architecture: modernization of enterprise systems that cannot afford downtime, portability across database engines, and observability at a scale of several hundred hosts. I create value where existing systems need to evolve without losing stability, coordinating the technical side with the client's teams and running development on an in-house AI agent harness: a framework that splits the work among role-based subagents, backs them with MCP servers and measures their cost.

Role: senior software engineer, from client analysis to delivery Stack: C#, .NET, Blazor Server, AWS CDK, OpenSearch, Zabbix, Claude Code and Codex Impact: modernization, platform, and technical coordination

Redytel

.NET Developer · technical project management

Development and evolution of .NET solutions for Redytel's iTuc systems, in the healthcare services domain. Work focused on legacy service modernization, architecture and quality of critical applications, data layer portability across engines, and platform observability. I also handle the technical management of the projects: I gather requirements directly with the client, analyze them and build them, and coordinate delivery with manufacturers and system owners. Development runs on an in-house AI agent harness.

AI agents across the whole cycle.NET and Blazor modernizationProject management and client workTeam technical leadObservability at scale
  • Integration of AI agents (Claude Code, Codex) across the whole development cycle through an in-house harness: subagents by role and model, in-house MCP servers and cost tracking of every run, with measured gains in efficiency and quality and technical judgment always my own.
  • Team technical lead: AI development methodology adopted by the team, supervision of two final-year degree projects, a development plan for junior engineers and weekly project reviews with written minutes.
  • Requirements gathered directly with the client: functional analysis of what they raise, a technical proposal for how to solve it, and building the solution, keeping the conversation open throughout delivery.
