Software engineering, product and applied AI

David Espínola

I help companies and product teams turn complex ideas into clear, scalable software ready to grow. I combine architecture, full stack development and applied AI to deliver solutions that solve real business problems.

About me

I work with companies that need more than code: they need to understand what to build, how to make it sustainable and which technical decisions will affect the business six months from now.

I have worked across consulting, banking, telecommunications, logistics, education and my own products. That mix lets me move between strategy, architecture and daily execution without losing sight of the end user.

If you have an idea, a blocked product or an important technical decision ahead, I can help you turn it into an executable plan.

  • JavaScript Programming

    I work with JavaScript, TypeScript, React, Node.js and Vue to create fast, maintainable experiences that are easy to evolve.

  • Databases

    I model data and optimize queries in relational and non-relational systems such as MySQL, PostgreSQL, MongoDB and Redis.

  • DevOps

    I automate deployments, containers and delivery workflows so teams can release with more confidence and fewer manual tasks.

  • Frontend Technologies

    I design modern, accessible and responsive interfaces with HTML, CSS, JavaScript, Vue, React and TypeScript.

  • Agile Methodologies

    I help teams prioritize, split work and deliver value continuously without losing the product's technical vision.

  • Mentoring and Leadership

    I support technical teams with practical feedback, shared standards and clear architecture decisions.
