Experience Highlights

Senior Front-end Developer
Feb 2023 - Ongoing1 year 3 months
Project Overview

Alberto has successfully built two applications. The first product was for the maintenance people in their locations. The second product was a complete solution for the organization that tracked what buildings they bought, would buy, or should buy with analyses using GPT-4. Alongside tables for the data, drag and drop functionality was implemented so they can assign people to different tasks (almost like Jira, but much better) and track the progress.

Responsibilities:
  • Created new micro-frontends and delivered features in a high-paced start-up environment.
  • Refactored the codebase using a standardized design system by creating and maintaining a components library. This library contained easy-to-use APIs and well-documented components. Easily testable and extendable. It also provided tremendous value to the design team, which could check the library by accessing the Storybook. This action removed much tech debt from the application and made onboarding new developers more straightforward.

Responsibilities:
  • Architectured the application from the beginning and demonstrated excellent technical, planning, and communication skills with the rest of the team.
  • Connected technologies like React Query and Redux with Nx on a micro-frontend architecture.
  • Implement screens containing lots of charts and data to handle. Had to make sure all the parts loaded in the factor of importance not to impact the user experience.
  • Created workshops for team members unfamiliar with the used tech stack(ex:React Query, Nx). At the end of the workshops, the team was more productive in delivering new features.

Responsibilities:
  • Implemented the entire business logic for the Timezone Components across the application based on the user location. This feature had to handle multiple edge cases because of the user's location. These Timezone Components were used everywhere in the application and had a high impact on how clients worked, so it was essential they run error-free.
  • Created reactive forms across multiple sections of the application. I had to use multiple optimization techniques to offer users a very smooth experience while navigating the multiple-form sections. Caching asynchronous data with React Query and keeping track of every step of the form while handling errors in real-time and autosaving users' data without putting pressure on the backend server.
  • Created new back-end Express services on a microservice architecture.
