I Design Scalable Backend & AI Systems (Spring Boot, LLM Integration, ERP, Fintech) If you need more than just a developer — if you need someone who understands both your business and how to build the system behind it — we should talk. I design and build backend systems for ERP, production environments, and data-heavy platforms, with a focus on scalability, reliability, and real-world usage. I’m not here to just write code — I help you structure the system, avoid costly mistakes, and deliver something that actually works in production. With 10+ years in software engineering and a background in production systems and business processes, I bring more than coding skills. I’ve worked on systems where downtime costs money, bad architecture breaks operations, and “just ship it” is not an option. That’s why I focus on: System design over quick hacks Scalable backend architecture Clean, maintainable solutions that survive real usage I typically help clients with: ✔ Designing backend architecture for SaaS and ERP systems ✔ Building scalable APIs with Spring Boot (high-load ready) ✔ Multi-tenant systems and data isolation strategies ✔ Integrating AI/LLM into backend workflows (automation, document processing, decision support) ✔ Refactoring broken systems that don’t scale ✔ Connecting complex systems (payments, external APIs, legacy systems) Unlike most developers, I understand the business side behind the system: Production & manufacturing workflows ERP logic and operational constraints Financial and data-driven systems This allows me to translate business requirements into working systems without endless back-and-forth. Tech I use when it makes sense: Java, Spring Boot REST / Microservices architecture SQL (MySQL, PostgreSQL, MSSQL) Kafka / messaging systems Docker / containerized environments AI integration (LLMs, APIs, automation pipelin
