As a freelance Full-Stack Developer, I built ESN Resource Manager end-to-end, from its PostgreSQL schema and REST APIs to a 34-page Next.js app. I implemented Keycloak authentication, role-based access, contract approvals, and a public job portal, with more than 460 backend tests.
I also designed FinanceOS, a multi-tenant finance SaaS with Spring Boot, including subscription billing, two-factor authentication, bank CSV imports, and a tax calculation engine. Earlier, at Key Object, I fine-tuned a résumé-extraction model and built a recruitment dashboard that reduced manual screening time by about 60%.
