The most amazing...

...thing I've done was develop the UI for a few complex apps from the ground up, including wireframing, UI/UX design, and programming.


  • Senior/Lead Front-end Developer

    • Defined and worked on crucial user interactions (e.g., pan and zoom, drag. and drop, transform, keyboard accessibility).
    • Improved performance by figuring out bottlenecks, optimizing critical path using caching, web workers, code splitting, lazy loading, algorithm improvement, etc., and using UX techniques to increase responsiveness and perceived performance.
    • Collaborated with designers, data scientists, and back-end engineers to implement the UI in the most engaging way for the user. Distributed tasks to other front-end team members.

  • Hasty – Image Annotation Tool for Machine Learning

    Hasty offers an efficient way to build a data science model for labeling images. I worked on a React-based front end, devising its architecture, implementing the annotation area and tools, and solving performance-related challenges.

  • Storage Management UI

    A web app for managing storage across clusters. I started from scratch by collaborating with a designer to build the UI, continuously added features such as cluster health monitor, disk management, and dashboard. Created charts in D3.js for data visualization and collaborated with the back-end team for integration through REST API and WebSockets. Managed several UI repositories and commons library.

  • UI Installer for a Storage Platform

    A web-based installer for on-premise deployment of a storage management system. Collaborated closely with deployment and backend teams to gather requirements and create a user-friendly installation workflow. Created complex forms, validations, and error handling.

  • Koolzone Automated Monitoring

    A dashboard displaying sensor data for freezers and fridges at hotels, breweries, or gastronomy sites. It allows monitoring the temperature, humidity, and pressure conditions in real-time and alerts if the sensor values go out of predefined boundaries. I was responsible for the architecture of the app, component design, implementation, and integration with the back end.
