I build production backend systems — Java/Spring Boot and ERPNext/Frappe are both first-line specialties for me, not a main-and-a-side. 100% Job Success Score across 49 completed jobs and $90,000+ delivered on Upwork, including a 990-hour single contract Java & Spring Boot: REST APIs and microservices secured with Spring Security and JWT, backed by JPA/Hibernate, deployed with Docker and CI/CD, running on PostgreSQL, MySQL, or MongoDB depending on the job. I've built everything from single services to multi-service architectures handling role-based access and third-party integrations, plus Java + React/Angular enterprise portals and Liferay 6.2/7.x portal work for clients who needed a full frontend layer, not just an API. ERPNext & Frappe: Frappe Certified on ERPNext V15. I handle end-to-end implementations — custom DocTypes, workflow automation, approval hierarchies, print formats, Frappe Cloud deployments and server setup, and REST API/Slack integrations connecting ERPNext to outside systems. Before I write a line of code, I ask two questions: what does your current process actually look like, and what does it cost you if this breaks? That's usually what separates a system that works from one that just runs. Currently available, 30+ hrs/week. I reply within a few hours.
