experience

With over 13 years of professional experience, I was extremely fortunate to have had the opportunity to work on exciting projects with very talented people.

I'm very proud of all that I have accomplished so far. It brings me joy to know that I have had a real impact, not only on the end result but also on the people I have collaborated with and end-users. Whether developing small or large projects, improving the experience of my colleagues and end-users, or solving complex problems, I always strive to give my best and have fun doing it.
In addition to my professional work, I constantly challenge myself with personal projects to continue learning and growing my skills.

I can't wait to see what comes next!

Interesting Projects

Over the years, I have been approached with a variety of unique challenges and ideas, as well as coming up with my own. Through these experiences, I have had the opportunity to work on some truly interesting projects, even with limited resources such as time. These experiences have helped shape me into the versatile and creative developer I am today.

Workflow Engine

Created a custom workflow engine that allowed end-users with the right permissions to create custom workflows, with several steps, approvals, permissions, routes, and more.

Form Designer (Absolute Position)

Created a custom form designer, that works with the custom Workflow Engine, that allowed end-users with the right permissions to create web forms, containing tabs and absolute positioned UI elements, by dragging and dropping. Some of the elements were somewhat advanced, like tables, and would contain custom properties that could be configured.

Form Designer (Responsive Layout)

Created a custom form designer that would replace the previous one, as a more modern and responsive option. Users could still drag, drop and resize elements, but the layout would be responsive, following the typical "12 column" grid layout.

Custom JavaScript Framework (jQuery abstraction)

Created a custom JavaScript framework based / on top of jQuery to use along with the previous options. This added infinite possibilities, along with customization and integration options. This framework was meant as a very easy-to-use programming language for our own and also end-users with the right permissions, where most of what was needed could be accomplished using its simple functions. The framework went through several iterations, and this also included maintaining its documentation accordingly.

Custom JavaScript Framework (Server-side / Scheduling)

As an extension to the previous idea, we also wanted to run custom logic from a server / scheduled, cron-like, perspective. This used PhantomJS and Chrome headless along with a Windows Service to trigger our code based on configurable triggers.

Code / Logic Wizard

Created a code / logic wizard, where end-users with no programming knowledge could easily configure their own logic. This included creating a very specific parser and code generator, and also included functions, conditions, and parameters.

PDF Text Extractor (OCR alternative)

Created a PDF text extractor, where PDFs were converted to HTML in a specific way that allowed end-users to configure zones from where to grab text information. This could then be easily integrated with the previous projects, and proved a much faster and accessible alternative to OCR.

Legacy Custom File Format PDF Extraction

Created a PDF extractor from a custom file format of a legacy app that was no longer maintained. It aggregated several files, including PDFs, which were required for our use-case. Had to evaluate bytes looking for file signatures without documentation as a guide, using the so-called "magic numbers" to identify when PDFs started and ended.

Data Matrix Code Scanner (Python Script)

Created a data matrix code scanner script in Python. The codes were scanned from a very large volume of TIFF files, so it had to be extremely optimized. Besides managing the local files, it involved counting the percentage of yellow on the image (based on a configurable RGB range), so that a correct amount of codes to be scanned could be calculated, in order to speed up the process significantly. Learned and used tools like numpy, CV2, Wand, and more. It also involved querying data from a MySQL database and integrating everything with web-based APIs.
