I specialize in automation and web app development and have tons of experience with all the technologies involved in the process, from writing the code to deploying the project.

I build digital tools and experiences, often programming the more complex pieces so others can use these tools to build the full web app. Additionally I advise what is possible to be done given a timeline and a budget and continue to share my impressions so we can adjust and manage risks based on how development actually progresses. It is time to kick off that new priority in your company! I work mainly with frontend and application logic, with basic infra skills to get my work online. By application logic I mean generating PDFs, payment processing, maps and vehicle routes, and so on. By frontend I mean what the user of the app sees, including very dynamic app screens. I have thousands of hours of work on these two plugins here, I use them as the flagship examples of my past work of creating plugins for a no code platform, one is a powerful PDF designer and generator that has worked reliably since 2018 and the other is a powerful multi purpose map component, it has a large variety of features  to meet a very wide array of use cases, see their links in the portfolio section please. As you can see I produced documentation and provided support as well, until I sold them both in 2024. I also made dozens of other plugins, including Stripe and other integrations, data dump processing (ETL), charts, VoIP and phone calls (Telnyx), browser extensions, automated scraping, SFTP client, code highlighter, words highlighter and a myriad other app logic needs. I also worked with different serverless functions providers, specifically Microsoft Azure functions, Netlify functions and AWS Lambda functions. Now, more recently I built Tupan, which is my current side project, also see its link in the portfolio section. Tupan is a nocode tool to create web apps. I made a write up on Tupan's internals and why I took each decision, you can see the link in the portfolio section too. So alongside general app logic and Bubble plugins, I have experience with: - SvelteKit which handles the frontend with dynamic and static pages; - Appwrite which handles the backend with users, functions, database and more, it is a Supabase alternative; - Docker to maintain the app online. - Caddy to serve as a whitelabel manager and front door of the whole stack. With me, you always get an instruction manual alongside the code. Projects include deployment to live, when applicable.

I am a web developer with almost 20 years of experience. I started to develop for the internet in 1999, writing Perl scripts to update a huge news website for the time. Since then, I've lost account of how many websites I deployed using the most different technologies, I've even went through the whole Flash website stuff, ugh. PHP, Python, HTML5, Javascript, jQuery, CSS, Mobile, SEO, MySQL, PostgreSQL, Memcached, Redis, Linux, etc.
