    I’m a full-stack developer with a frontend background — seven years of experience building interfaces that feel fast, intuitive, and reliable, and two years working across the stack. I mostly work with React, Next.js, and TypeScript on the frontend, and Node.js, Express, and PostgreSQL or MongoDB on the backend. I’ve worked on dashboards, data platforms, crypto projects and e-commerce apps — anything from building something from scratch to refactoring messy legacy code. I’ve written over 1,000 unit and integration tests to keep things stable, set up Docker-based CI/CD pipelines, and enjoy figuring out how everything fits together. What drives me is making things clear and usable — both for users and for the developers who’ll work with the code after me. I work well in teams, enjoy talking through problems, and like being part of the full process, from design ideas to deployment.

    “Simply one of the best freelancers I've worked with on Upwork.” “Richard knocks it out of the park on every project we work on together!” “Top notch work, and an amazing experience as always.” “I cannot emphasize enough just how professional, diligent and thoughtful Richard has been.” Most of my work is with VBA. I particularly specialize in 2 types of job: ➤ Automated production of Word/PDF documents (from custom mail merges to complex multi-template documents). ➤ Connecting to web APIs (including HubSpot, SalesForce, Google, Bing, Quandl, USPTO). My work often includes: ➤ Advanced spreadsheet formulas ➤ VBA add-ins ➤ Data entry forms ➤ Power Query (intermediate level) ➤ User guides and other documentation I aim for a good balance between cost, code quality and processing speed. Please let me know if you would like to prioritize one of these 3 variables. Many VBA freelancers started as Excel users and then taught themselves to program in VBA. I've come from the opposite direction, with a background in software development. This gives me an advantage in building complex VBA programs with well-structured, readable, maintainable code. Sorry, I only work with Windows, not Mac.
