Summary

Senior Software Engineer and Tech Lead with 13+ years of experience designing and building scalable, secure, accessible, and high-performance digital products. I combine technical leadership with hands-on engineering, drawing on deep expertise in full-stack development and extensive experience in e-commerce. I drive the adoption of agentic AI across the entire software development lifecycle, from product definition and design to development, testing, and DevOps, to accelerate delivery and improve team productivity.

Experience

Senior Software Designer Glob.AI (Globant)

Full Time – Present (10 months)

  • Lead a team of 4 (technical direction, planning, quality standards, and mentoring) building the Corporate Hub WebApp, the interface to Glob.AI OS's enterprise data plane for AI agents and business teams.
  • Built 8+ complete UI modules for the web platform to manage data resources (data sources, data stores, datasets, ontologies, and more) with the Product and UX teams, following Spec-Driven Development.
  • Designed and built the BFF between the WebApp and the data plane, with a unified, versioned OpenAPI contract spanning ten resource families, for the multi-tenant, multi-cloud platform (AWS, Azure, and GCP).
  • Created the repository and designed and built the architecture of the Corporate Hub MFE, with a complete agentic harness (context engineering, skills, subagents, hooks, scheduled tasks, and guardrails) built in to support agent-driven development.
  • Design and maintain the data plane's integration surface: 4 SDK libraries for developers (TypeScript, Python, Java, and Kotlin, generated from a single spec), an MCP server for AI agents, and a REST API for the business layer.

Key Competencies

Technical judgment and critical thinking: Apply sound engineering judgment to technical decisions and solutions, identifying trade-offs and prioritizing simple, robust and sustainable approaches. Maintain a critical perspective on results and challenge assumptions when necessary.

Autonomy and decision-making: Lead initiatives end to end: clarify ambiguity, establish context, assess risks, make technical and strategic decisions, anticipate blockers and drive execution through to the intended results.

Ownership and accountability: Take full ownership of results, beyond implementation. Ensure quality throughout the lifecycle, including testing, deployments, observability and production behavior.

Problem-solving and systems thinking: Approach complex problems holistically: identify root causes, evaluate alternatives and design efficient, scalable solutions aligned with business objectives.

Technical excellence and quality: Champion consistent engineering standards, prioritizing simple, focused and maintainable code (KISS, DRY, YAGNI, SOLID). Design and refine AI agent harnesses (context, rules, hooks and skills), upholding these standards through code reviews.

Collaboration and technical influence: Work effectively with cross-functional, international teams, fostering clear communication, sharing knowledge and building technical consensus to achieve shared goals.

Adaptability and technology adoption: Adapt quickly to new paradigms and technologies. Continuously evaluate and adopt tools and practices that improve productivity, quality and efficiency across the software engineering lifecycle, particularly through agentic workflows.

Automation-first mindset: Proactively seek out ways to automate repetitive workflows, from rigorous CI/CD pipelines and automated testing to the integration of agentic AI tools. Driven to reduce manual toil, minimize human error and optimize overall developer productivity.
