Work Background
Tata Consultancy ServicesFull Stack Developer
Jan. 2022 - Apr. 2024Colombia, BogotáI improved the look and feel of the system implementing new and intuitive ways to interact with the screen using new components and elements based on market trends. I managed to make an improvement in the massive database insertion with the current infrastructure of the project achieving a pool of 20 database connections but inserting around 5 thousand records. This improvement is important because when inserting records previously used 1 connection to the DB for each record, generating a pool of 5 thousand requests to the database causing it to collapse. I improved the service in charge of sending emails allowing to attach files and HTML code to improve the aesthetics of them. This idea was shared with the DEV team and its operation was also explained.
SMILE SOLUTIONS SASDesarrollador de software
Jan. 2021 - Feb. 2022Colombia, MedellínI was able to create an automatic email in charge of sending reports of the day's sales, expenses, balances and other reports to the users of the application in order to improve the processes and decision making of the clients. I reduced the loading time of some functionalities and forms by refactoring the code and optimizing database query processes using Hibernate in order to improve the user experience in the application. Implemented an API to send sales data to other applications that customers manage in order to improve the customer experience when generating reports and make their decisions smoothly between the different applications they can use. I solved 30% of the backlog bugs in the offline POS system developed in Nodejs and Angularjs, getting users to use this second application to sell their products offline. I increased by 70% the performance of the database by changing the old stored procedures by JPA Hibernate in Java in order to improve the speed of massive information queries in the reports.
Servicio Nacional de Aprendizaje (SENA)Desarrollador de aplicaciones
May. 2019 - Apr. 2020Colombia, MedellínI managed to create a desktop application in .NET with the ability to synchronize with a web service that contains a database that the client can program and update from any device. I solved a data connection problem between the sites where the application is installed by creating a web service that connects all the sites and synchronizes them.
