Core Pillars

Areas of Expertise

Where technical depth meets measurable business impact

DevOps & Deployment

I don't just write code — I ship it. From containerizing applications with Docker and building fully automated CI/CD pipelines with Jenkins, to managing enterprise-scale storage with MinIO / S3 and executing zero-loss data migrations of 467,000+ documents, I own the full delivery lifecycle. Your product reaches production reliably, and your data stays safe.

Backend Development

Rock-solid backend systems are the engine of every great product. I build high-performance, production-grade APIs and services using Java & Spring Boot, backed by Hibernate / JPA for efficient data persistence. Every line of backend code I write is designed for scalability, maintainability, and real-world production loads — not just to pass a demo.

Java 17 / 21Spring BootHibernateJPAREST APIs

Microservices Architecture

I architect distributed systems that scale independently and fail gracefully. Using Spring Cloud and Eureka for service discovery, I wire resilient ecosystems powered by Kafka and RabbitMQ for decoupled, event-driven communication. Distributed tracing with Zipkin and full observability via Prometheus & Grafana ensure you always know exactly what your system is doing in production.

Secure Applications

Security is not optional — it's a requirement. I implement enterprise-grade authentication and authorization using Spring Security, OAuth 2.0, and OIDC standards, with Keycloak as the identity provider and JWT for stateless token management. Your users' data and your business logic are protected by industry-standard security protocols from the ground up.

Performance Engineering

Slow APIs kill businesses. I go deep into the JVM to diagnose and eliminate hidden performance killers — N+1 queries, inefficient JPA mappings, missing indexes. By introducing strategic caching and optimized fetch strategies, I achieved a 70% reduction in API latency in production. I don't just fix symptoms — I eliminate root causes.

Frontend Excellence

A powerful backend deserves an equally polished interface. I build reactive, component-driven frontends in Angular 16 with RxJS and TypeScript — delivering fast, accessible, enterprise-grade UX that users actually enjoy. From complex data tables to real-time dashboards, I turn requirements into seamless experiences.

Real-world impact at enterprise scale

01 Cloud Migration

Document Migration Service

Engineered a fully automated pipeline to migrate 467,000+ enterprise documents from a legacy file system to a MinIO S3-compatible object-storage cluster. Wrote deterministic MySQL validation scripts guaranteeing 100% data integrity post-migration. The service handled chunked streaming, retry logic, and idempotent operations to ensure zero data loss across multi-day migration windows.

▶ 467k+ documents successfully migrated
▶ 100% data integrity validated via MySQL scripts
▶ Zero downtime, resilient retry mechanism

02 Modernization

Legacy System Refactoring & Modernization

Took ownership of a business-critical VM-based monolith and led its architectural evolution toward a containerized, cloud-ready microservices design. Performed systematic JPA optimization — eliminating N+1 fetch problems and introducing second-level caching — achieving a 70% reduction in API latency. Integrated CI/CD with Jenkins and enforced quality gates via SonarQube.

▶ 70% latency drop after JPA & caching overhaul
▶ Migrated from VM to Docker-based deployment
▶ SonarQube quality gates integrated in CI pipeline

03 Full-Stack

CEE Workflow Management System

Architected and developed a large-scale web application for managing complex operational workflows across a multi-entity enterprise environment. Built a reactive, component-driven Angular 16 frontend backed by a Spring Boot REST API, with Kafka-powered async processing and Liquibase-managed schema migrations. Mentored two junior engineers throughout the delivery cycle.

▶ End-to-end full-stack ownership (Angular + Spring Boot)
▶ Kafka async event processing at scale
▶ Mentored junior engineers on design patterns & testing

04 Finance & Compliance

European VAT & Tax Management Platform

Designed and developed a comprehensive platform for managing VAT declarations and tax compliance across multiple European jurisdictions. Built a robust Spring Boot backend with PostgreSQL for transactional data and MinIO for secure document archival. Delivered a modern React-based frontend for real-time tax reporting dashboards and automated regulatory workflows.

▶ Multi-country VAT compliance engine
▶ Real-time tax reporting dashboards with React
▶ Secure document storage via MinIO (S3-compatible)

Topographer Agency Management System

Architected and delivered a domain-specific management platform for topographer agencies, handling project tracking, land survey records, client management, and geospatial document workflows. Powered by Java 21 and Spring Boot with an Angular frontend, containerized with Docker, and deployed to Oracle Cloud Infrastructure via Jenkins CI/CD pipelines.

▶ Survey project & geospatial document management
▶ Dockerized deployment on Oracle Cloud
▶ Jenkins-powered CI/CD for continuous delivery

07 Spring Boot

Stock Management Web Application

Web application for stock management, analyzed, designed and developed with Spring Boot on the backend and Thymeleaf + Bootstrap on the frontend. The project provides a flexible alternative to traditional methods like Excel, which often suffer from security, performance, and information-retrieval issues. The application manages core stock modules such as products, orders, customers and suppliers while taking security and performance constraints into account.

▶ Management of products, orders, customers and suppliers
▶ More secure and higher-performing alternative to Excel
▶ Spring Boot backend with Thymeleaf + Bootstrap UI
