My experiences range from building restful APIs, Daemons Unix, Services in Windows (c# .net framework), and Real-time applications with a longtime connection through sockets and protocols like gRPC, graphQL in the language C, C#, Javascript, Node.js, and Java. I’ve worked with popular frameworks like express.js, sail.js, nest.js, Spring boot, and others. Regarding the frontend topic, I have the basic knowledge required to understand HTML5.
EXPERIENCE
- I work as a Full-stack developer providing development services creating a backend application from scratch, and giving maintenance to the integrated systems. I’m providing system architecture and system design proposals for internal systems.
- Created backend integration from scratch that allows the transfer of financial information to a 3rd party ERP system to automate payment and sales processes. The stack chosen is Typescript, nest.js framework.
- Created system designs using the Microsoft Visio application that work as documentation of the integration.
- Design proposal for refactoring and performance improvements for internal batch processing.
Software Engineer — Jun 2021 – Sep 2022
- Started as a software engineer focusing on the backend, the project was about DNA and genetics, so in the first weeks, I was getting onboarded by Bio-Informatic people and Doctors. I learned about how the essay extracts genetic information, so you can detect early diseases and future problems to prevent them.
- Added features in the essay steps to control incoming information in the python applications.
- Fix some inconsistencies in the Django view engine, which does not display the correct information for genetic people.
- Improve performance on database queries by adding more conditional statements to filter the data better and implement compute functions like AVG and SUM on PostgreSQL database queries to avoid doing that on the codebase.
