Software Engineer · Full Stack Development · Systems Integration · Process Automation

I'm an Information and Communication Technology engineer building and maintaining software since 2021, first at izzi telecom and now at BBVA México.

I like taking complex operational processes and turning them into systems that work. That often starts with an incident, a repetitive task, or a gap between applications. I investigate the cause, work through the business rules, and carry the solution through implementation and validation.

My work spans backend services, APIs, databases and web interfaces, with a particular interest in reliability and automation. Outside my day job, I lead independent software projects from product definition through development and testing.

• Full stack development — backend services, REST APIs, relational data models and the interfaces people use to work with them.
• Systems integration — connecting applications and data so processes can run with fewer manual hand-offs.
• Process automation — translating operational rules into configurable workflows, including assignment, prioritization and notifications.
• Reliability and root-cause analysis — investigating failures and designing retries, recovery paths and controls that address their causes.
• Engineering practice — automated tests, CI workflows, environment separation and documented technical decisions.

Development and integration of technology solutions, with a focus on incident analysis, process automation and structural improvements to existing systems.

• Investigated saturation and failure handling in a bulk email processing service, proposed a redesign, and implemented retry and prioritization mechanisms. The change was approved and implemented; production enablement remains pending.
• Work across applications, APIs and operational workflows to identify root causes and turn improvement proposals into working software.

Full stack development and maintenance of internal web applications using Laravel, PHP, JavaScript, Node.js, Vue.js, MySQL and SQL Server.

• Built a rule-based incident assignment system for call center agents, with configurable assignment rules and per-area quotas.
• Developed and maintained the backend, database and web interface layers supporting internal operations.

A modular platform for independent dentists and accounting practices in Mexico, shaped by conversations about how they manage appointments, fees, documents and collaboration.

I lead product definition, priorities, acceptance criteria and delivery review, using AI coding assistants throughout development. The work includes a navigable prototype, backend development and automated checks, with an emphasis on simple workflows, access permissions and controlled operating costs.

Technologies: Python · FastAPI · PostgreSQL · JavaScript · Firebase Authentication · Playwright · GitHub Actions
Status: In development and commercial validation. Private repository; not yet a production service.

A volunteer project for Iglesia Cristiana Shalom, covering children's ministry workflows and a broader community platform.

The work spans an existing QR attendance system for Shalom Kids and a separate platform prototype for families, volunteers and administrators. I lead requirements, workflow design and development with AI assistance, including documentation and usability review.

The public prototype uses fictitious data to gather feedback. The future platform has a separate React and Django foundation; it does not replace the operational Kids system yet.

Status: Public prototype and version 1 foundation in development. Private repository.

A workflow extracted from my own projects for making AI-assisted development easier to review and trace.

It separates implementation from independent review and provides project control documents, decision records, CI checks, release automation and configuration checks. I define the goals and acceptance criteria, review evidence and keep responsibility for the resulting product.

Tools I use across professional work and independent projects:

I run NoMeVendasHumo.mx, a Spanish-language project about fabrics, materials and build quality. I look at what products are made of and whether their construction supports their marketing claims. That curiosity also shapes how I approach engineering: understand how something works, then check the evidence.
