Project details
Stop paying for generic, insecure ChatGPT wrappers. You need a robust, custom AI workflow that actually saves your business time and money.
I am Dimitrios, a Senior Backend Architect with over a decade of experience—including 3.5 years building highly secure, business-critical microservices for Nordea Bank. I specialize in integrating Large Language Models (OpenAI, Groq) and Agentic AI (AutoGen) into secure, scalable backend environments.
Whether you need to automate a massive data pipeline, build an AI recruitment agent (like my platform, JobWorm), or integrate LLMs into your existing Java/Spring Boot legacy system, I build systems that don't crash in production.
My Core Deliverables: • Custom AI Agent Development (AutoGen) • Secure LLM API Integration (OpenAI, Groq, LLaMA) • Automated Data Workflows & Complex Web Scraping • Custom Database Schema Design (SQL/NoSQL) • Production-Ready Backend Architecture
I do not write fragile code. I build secure, banking-grade systems. Let's discuss your requirements and automate your business today.

About Dimitrios
Senior Backend Architect | Java, Spring Boot & AI Integrations
Uppsala, Sweden - 11:46 pm local time
I am a Senior Backend Architect specializing in the Java/Spring ecosystem, high-security Fintech/Banking infrastructure, and modern AI integrations.
With over a decade of backend engineering experience—including 3.5 years architecting highly secure, business-critical microservices for Nordea Bank—I don't just write code. I partner with stakeholders to solve complex business problems, designing and deploying scalable, production-ready systems from the ground up.
Most recently, I engineered and deployed two complex SaaS platforms:
LiveFooty: A high-performance real-time data pipeline that ingests, filters, and mathematically processes live sports data into lightweight JSON APIs.
JobWorm: An AI-powered recruitment platform featuring complex LLM workflow automation, custom database architecture, Stripe monetization, and complex web scraping.
CORE TECHNICAL EXPERTISE:
Fintech & Backend Architecture: Java, Spring Boot, Spring Data JPA, Hibernate, KYC & Risk Flows.
API Design & Development: RESTful, secure, high-performance, banking-grade data pipelines.
Database Design: MySQL, MongoDB, scalable schema design.
AI Integration: Connecting LLMs (OpenAI, Groq) and Agentic AI algorithms to backend services.
Cloud & Deployment: Server Optimization, System Scaling, API security.
Whether you need a Senior Architect to rescue a failing backend, design a secure Fintech API, or integrate Agentic AI into your legacy platform, I deliver clean, maintainable, and highly efficient systems.
Let's jump on a quick call to discuss your project's technical and business requirements.
