March 2026 delivered meaningful enhancements across frontend and backend, expanding candidate data capabilities, enriching data sources, and strengthening automation workflows. The work focused on delivering business value through improved user experience, broader data coverage, and more reliable, scalable processes. Key outcomes include: - Expanded candidate data handling in the frontend EditModal, enabling candidate_json support to streamline candidate management and data propagation between UI and backend. - Integrated trueup.io as a new job data source, widening job listings and updating UI filters to reflect the new source. - Strengthened backend candidate marketing workflow with JSON parsing, validation, and improved integration with automation sites, reducing manual data wrangling and errors. - Overhauled automation workflows and trigger runs, consolidating API endpoints/routes for triggering the Job Application Engine, scheduling, run parameter updates, and data enrichment to accelerate automation cycles. - Added trueup.io job listings support on the backend with ORM enum cleanup to improve data integrity and consistency across services. Impact and value: with higher-quality candidate data, broader job data coverage, and more reliable automation, the team shortened cycle times for candidate outreach, expanded market reach for job listings, and improved system stability and maintainability. Technologies/skills demonstrated: frontend React/UI data handling, JSON parsing, data validation, API design, ORM enum modeling, automation orchestration, environment and data handling improvements, and dependency stability through version pinning (see separate commits).
