Project Overview

Hollo.io was a modern recruitment platform built by recruiters, for recruiters — later adopted as the internal core platform for Job2BeDone, a headhunting firm specializing in major accounts. Unlike traditional job boards with basic interfaces, Hollo.io delivered a highly dynamic and interactive experience designed to streamline complex hiring workflows. I joined J2BD Partners to take over from the previous development team, complete the candidate-facing side of the platform, and stabilize the already-released recruiter interface.

Our Approach

We focused on continuity and quality — inheriting an existing codebase and bringing it to a production-ready state. The recruiter interface was already live but unstable, so we balanced bug fixing with new feature delivery. On the candidate side, we built from a partial foundation toward a full release, prioritizing UX and interface responsiveness. Heavy JavaScript work was central to delivering the fluid, dynamic feel that sets the platform apart — and that ultimately made it valuable enough to become Job2BeDone's internal tool of choice.

Key Features
  • Candidate Platform Launch — Completed and shipped the candidate-facing side, delivering the full end-to-end product experience.

  • Recruiter Interface Stabilization — Debugged and hardened the live recruiter platform, improving reliability across core hiring workflows.

  • React Component Development — Built and optimized reusable UI components to deliver a highly interactive interface far beyond standard recruitment tools.

  • REST API Development — Implemented backend endpoints in Node.js to support seamless data flow across the platform.

  • Chrome Extension — Developed a JavaScript Chrome extension to extend the platform's reach directly into the recruiter's browser workflow.

  • UI/UX Design — Designed interfaces in Figma ensuring consistency and usability across the full product.

  • Agile Collaboration — Contributed to sprint planning and project coordination within a cross-functional agile team.
