Built Metro One’s Network Recruitment Module (NRM), a referral-based hiring platform that sources candidates from
employee and affiliate networks instead of job boards, on Next.js 16, React 19, TypeScript, and PostgreSQL.– Implemented core referral workflows: network matching by skills and geography, staged outreach campaigns,
first-ownership referral attribution, and ATS milestone tracking that drives reward payouts.– Engineered a radius-based notification engine for geo-targeted campaigns; staged workflows with notification batching
eliminated duplicate outreach, alongside dynamic incentive processing.– Modeled a 20+ table normalized PostgreSQL schema (referrals, campaigns, notifications, grading, payments) and built
typed DataSource/store CRUD layers and server actions behind admin portals for jobs, campaigns, affiliates, and
rewards/payouts.– Integrated external HR systems (WFM/Workday, ATS) through scheduled sync jobs, and secured the app with NextAuth
role-based access control supporting 10K+ users across multiple organizational hierarchies.– Cut API response times by 50% (800ms → 400ms) by refactoring SQL queries and optimizing database indexes.– Shipped a module-based UI (admin, workflows, HR/finance areas) with Shadcn/Radix, covered by Vitest and Playwright
automated tests.– Delivered course-management and class-scheduling features for an enterprise LMS, and automated Quarterly Business Review
