Andres Barradas

Engineering Lead · Full-Stack · AI Engineering

Software engineer with 10+ years building and leading web platforms, including leadership as an Engineering Lead. I focus on robust, scalable systems that solve real business problems, and I stay hands-on with modern web technologies, clean architecture, and the tooling that improves developer experience and product quality. More recently I have folded AI-assisted workflows into how I work, with engineering fundamentals still doing the load-bearing work.

Experience

  1. Senior Software Engineer · Artemis

    Sep 2025 — Present · 11 mos · United States · remote from Medellín, Colombia

    Artemis, a Monalee product. Built production 3D design-editor systems — geometry, volumes, spatial interaction, rendering and performance — alongside an applied-AI pipeline that used multimodal embeddings and vector search to route utility-bill extraction.

    • Engineered production 3D editing and modelling workflows across geometry, volumes, planes, spatial transformations, object placement, measurement, snapping, distance constraints, selection, dragging, and rotation.
    • Worked across the 3D fundamentals the editor rests on — raycasting for selection and placement, shading, layering, and coordinate-system transforms — and the interaction design that makes sophisticated modelling tools feel understandable.
    • Improved the reliability of complex editor interactions across mixed coordinate systems, tilted surfaces, invalid placements, collision rules, and changing edit states.
    • Strengthened rendering and runtime performance by reducing work in frame-sensitive paths, batching state updates, improving resource lifecycle management, and eliminating avoidable allocations and UI recomputation.
    • Integrated design validation directly into the 3D editing experience, so users could identify invalid configurations and recover without interrupting their workflow.
    • Built an AI-assisted utility-bill analysis system using multimodal embeddings and pgvector similarity search to retrieve, score, and rank the closest historical documents.
    • Used those nearest matches to select an extraction strategy per document, with validation, integrity checks, and fallback behaviour for unfamiliar inputs — embedding-based retrieval and intelligent routing, the patterns RAG systems are built on.
    • Delivered full-stack product work across React interfaces, backend services, APIs, persistence, automated testing, CI, observability, and production reliability.

  3. Engineering Lead · Rappi

    2021 — 2025 · Medellín, Colombia

    Led cross-functional engineering teams of up to 12 building and maintaining mission-critical applications for Rappi operations, owning system design as well as delivery.

    • Led cross-functional engineering teams of up to 12 (front-end and back-end) building and maintaining mission-critical operations applications.
    • Oversaw system design and architecture decisions, including microfrontends, SOLID principles, and DevOps practices for scalability and high availability.
    • Drove technical mentoring for junior and mid-level developers, running knowledge-sharing sessions on clean code, design patterns, and cloud services.
    • Partnered with product managers and stakeholders to align technical solutions with business goals, managing timelines and deliverables.

    Software Engineer

    2018 — 2021 · Bogotá, Colombia

    Re-architected front-end systems across several Rappi business verticals, building the shared libraries other teams built on top of.

    • Contributed to re-architecting front-end systems with microfrontends, and developed internal libraries that streamlined common UI components and improved time-to-market.
    • Built and maintained applications serving multiple business verticals — ERP, CMS, and mobile widgets.
    • Integrated REST and GraphQL APIs and worked across MongoDB, PostgreSQL, and MySQL for internal tools and external-facing services.
    • Worked closely with design, product, and operations to turn business requirements into high-performing apps.
  4. Full-Stack Developer · JPC Apps

    2016 — 2018 · Spain · remote from Puerto Ordaz, Venezuela

    Worked remotely from Venezuela for a Spain-based company, building full-stack products and running the client relationship directly with European stakeholders across time zones.

    • Designed and developed back-end microservices in Node.js, integrating them with a React and HTML5/CSS3 front-end.
    • Worked directly and continuously with European end clients to gather feedback, define iteration cycles, and plan project roadmaps.
    • Employed unit and integration testing alongside CI/CD pipelines to keep code quality and deployments predictable.
    • Implemented real-time streaming and interactive features across multiple verticals.
