Onlio APS

Jira workflow modules

  • Technical direction
  • Module ownership
  • Backend API coordination
  • Performance improvements

Frontend Tech Lead [2024-2025]

Brought in to extend a customized Jira instance for a major bank, I assessed requirements with management, highlighted complexity and risk, proposed alternatives, and then designed and delivered the solution. Beyond the new modules, I refactored legacy areas to optimize performance.

I was accountable for the frontend scope end to end, from solution design to release.

Feature module highlight

An Excel-like grid module with 25+ columns, conditional fields, real-time validation, and backend lookups. Users could create, edit, and copy rows at scale, so rules and feedback had to stay consistent across related fields even with thousands of rows. Filtering, sorting, and rendering required tight implementation to keep the UI responsive and avoid unnecessary network traffic.

Lead Frontend Engineer [2021-2024]

As one of the lead engineers, I guided a greenfield project's development for one of the biggest insurance groups in Europe and established foundations for multiple lines of business.

My responsibilities encompassed mentoring developers, setting coding standards, conducting thorough code reviews, contributing to architectural decisions and presenting our work to stakeholders.

In summary, my role comprised over half of my capacity dedicated to technical analysis, refinement sessions, code reviews, and assisting developers in overcoming challenges. The remainder of my responsibilities involved the implementation of complex features and continuous efforts to enhance the quality of our codebase.

Achievement

One of my notable achievements was the complete refactoring and stabilization of our custom application state management system, which was later adopted by all teams and became critical to meeting a major release deadline. During the final phase, I secured two senior developers to work alongside me and coordinated the integration of the new application state with features that were developed concurrently by other teams.
