I help startups, scale-ups, and enterprises build high-performance SaaS platforms, AI-powered applications, marketplaces, and enterprise systems that are secure, scalable, and built for long-term growth. My core expertise is Go (Golang) backend architecture, distributed systems, microservices, API development, and cloud-native applications. I also deliver Angular and Flutter applications when projects require end-to-end ownership from architecture through deployment. I leverage modern AI technologies including OpenAI, Claude, Agentic Workflows, RAG (Retrieval-Augmented Generation), and MCP-based integrations to help businesses automate processes, improve user experiences, and unlock new revenue opportunities.

Most ERPNext projects go over budget and under-deliver — not because the software is wrong, but because the implementation ignored how the business actually operates. That's the problem I've spent 13 years fixing. I build ERPNext implementations and Spring Boot backend systems for startups, SMEs, and enterprises that need things done right the first time. I'm Frappe Certified on ERPNext V15, and I've completed 38+ projects on Upwork with a 100% Job Success Score across $90,000+ in work — which means clients come back, and they refer others. 𝐖𝐡𝐞𝐫𝐞 𝐈 𝐚𝐝𝐝 𝐭𝐡𝐞 𝐦𝐨𝐬𝐭 𝐯𝐚𝐥𝐮𝐞: On the ERPNext side: end-to-end implementations, custom DocTypes, workflow automations, approval hierarchies, print formats, custom scripts, and REST API integrations with third-party tools. I understand the Frappe framework deeply enough to build what the standard modules can't. On the backend side: Spring Boot REST APIs and microservices with proper security (Spring Security, JWT, RBAC), JPA/Hibernate, clean architecture, and production-ready deployments. I've also handled Liferay 6.2/7.x portal development and Java + React/Angular enterprise portals for clients who needed both ERP and a custom frontend layer. What separates working with me from working with a developer who just executes tickets: I ask the two questions most developers skip before starting — what does your current process actually look like, and what does failure cost you? That conversation shapes everything and usually saves weeks of rework. Currently available. I reply within a few hours.
