Profile

I’m a senior full stack developer with almost 20 years of experience in software architecture, cloud infrastructure, product strategy and market validation.

My technical versatility covers all parts of software development: from designing the system architecture and implementing it with different frameworks to developing CI/CD pipelines in the cloud. I’m equally comfortable building pixel-perfect, high-performance React components as I am designing APIs and integrating AI capabilities.

I bring significant startup experience from joining several companies in their early stages and I remain focused and pragmatic in the controlled chaos of such environments.

I am most useful when priorities change fast or a problem does not fit neatly inside one role. Managers often turn to me to test assumptions about what to build or work through technical problems without obvious answers, while I remain hands-on with architecture and code. I combine technical expertise with an entrepreneurial mindset to build useful products.

Recently, I founded and sold an AI invoicing product and built a production RAG system that processed thousands of mining-related documents each day.

Experience

Senior Software Engineer

YLD Agency (2025 - 2026)

  • Joined on a short fixed-term contract to cover an employee’s sabbatical and contribute to an open-source platform for coordination among Parkinson’s disease researchers: ASAP Hub.
  • Implemented webhook pipelines with AWS EventBridge, SQS, and Lambda to index data in OpenSearch and defined OpenSearch aggregation and query-boosting strategies for data retrieval.
  • Led the React 18 migration of a six-year-old monorepo with multiple applications and shared packages. This meant updating more than 10,000 tests under a 99.99% test-coverage requirement.
  • Resolved React 18 compatibility issues involving React Router, React Testing Library, linters, libraries, and bundlers.
  • Planned and coordinated this migration with developers and management so feature delivery could continue throughout the work.

Tech Lead

Digbee (2019 - 2025)

  • Designed Digbee’s AWS infrastructure and led a three-person development team through the adoption of Docker, multi-server CI/CD pipelines, and automated releases with GitHub Actions.
  • Established unit, end-to-end, and manual testing practices and added pre-deployment database checks. Set up centralized logs, monitoring, and alerts to track issues in production.
  • Designed, built and maintained the document-ingestion system behind the company’s main revenue-generating product. It processed thousands of mining ESG documents each day using OpenAI embeddings, vector stores, S3, and structured LLM outputs.
  • Built cloud systems for PDF and image generation, background job queues, embeddable widgets and UI component libraries.

Founder

Entrepreneurial Projects (2024 - 2026)

  • Built Adviara: invoicing software for the Andorran accounting market that used Qwen open-weight models on private infrastructure to recognize and track invoices, purchase receipts, reports, and other documents.
  • Sold Adviara in March 2026. The product remains in use by accountants in Andorra to manage their clients.
  • Built TukiDocs, a document-processing system that used configurable templates, image recognition, and structured OpenAI outputs to turn IDs, invoices, passports, and other documents into standardized records. The project has been discontinued.

Senior Full-Stack Developer

Various Companies (2007 - 2019)

  • At SENSU K.K. in Japan I built a Google Drive-like product for professional photographers and managed its AWS infrastructure. Virtualization kept its complex React animations running at 60 FPS (watch demo).
  • Served as technical lead during Flowics’ startup phase. Designed a WYSIWYG web builder that let nontechnical users create responsive websites, including its drag-and-drop and data-visualization systems (watch demo).
  • Developed core front-end interactions during Mural’s early product development, including element rotation, rich-text editing, board scaling and zooming, and physics-based behavior before JavaScript libraries existed for those problems (watch demo).
  • Notable positions at Network Solutions and Globant developing cross-browser JavaScript applications.
