Building Secure, Scalable Java Backends for Enterprise Impact

Delivering High-Performance APIs, Microservices, and Data-Driven Solutions

As a Senior Java Engineer, I specialize in designing and deploying robust, scalable, and secure backend systems that power enterprise-grade applications. With deep expertise in Java, Spring Boot, and Hibernate, I architect distributed microservices, optimize database interactions, and implement industry-standard authentication protocols (OAuth2, OIDC, SAML) to protect critical data and services. My approach blends Agile development, rigorous code quality standards, and advanced DevOps strategies—Terraform, Docker, AWS—to ensure every release is both reliable and cost-effective.

From integrating SQL and NoSQL databases for lightning-fast queries to leveraging containerized environments on AWS EKS, my goal is to streamline the full software lifecycle. I prioritize maintainable code, automated testing, and continuous integration to produce solutions that evolve seamlessly as business requirements grow. Let’s collaborate to transform complex challenges into scalable, future-proof Java ecosystems that drive tangible business value.

How may I help you?

Enterprise-Grade Java Microservices

I create resilient microservices using Spring Boot and Spring Security, translating complex requirements into elegant, maintainable codebases. By applying MVC principles, JPA/Hibernate for data persistence, and Spring Data for streamlined repository management, I ensure consistent performance and robust error handling. My microservices integrate seamlessly with RESTful APIs, event-driven architectures, and asynchronous communication patterns, resulting in systems that adapt smoothly to dynamic workloads without compromising stability or security.

Secure, Standards-Compliant APIs

Security is embedded in every service I build. I implement OAuth2, OIDC, and SAML, aligning with IETF and PKI best practices to safeguard sensitive data and enforce strict access controls. By configuring SSL/TLS, rotating keys, and monitoring for vulnerabilities, I create APIs that withstand modern threat landscapes. The result: services that pass stringent compliance checks, uphold user privacy, and foster trust among customers and stakeholders.

Cloud-Ready Deployments & DevOps Excellence

My solutions are cloud-native by design, leveraging AWS services like EKS, EC2, S3, and RDS for unmatched scalability and reliability. Infrastructure as Code (Terraform) and containerization (Docker) empower teams to replicate environments swiftly and consistently, reducing configuration drift and accelerating disaster recovery. Integrating CI/CD pipelines (Jenkins, GitHub Actions) ensures that each code commit is thoroughly tested, validated, and ready for seamless deployment. By merging DevOps best practices with Java engineering, I deliver features faster, cut release cycles, and maintain consistently high-quality standards.

Google Analytics training for companies

It doesn’t matter if you’re small e-shop or huge corporate. The data that’ll help you find deficiences or find opportunities is extremely valuable. Unfortunately it’s not enough to “have” it – it’s important to know what to do with it.

That’s the reason why one training is much better than tens of hours staring into Google Analytics interface. You’ll learn how to find and leverage the data you have.

Google Analytics training for companies

1. What's your level

At first we'll align ourselves on the starting point - we'll find out what you already know, what are your business pillars and what do you want to learn.

Google Analytics training for companies

Complying with principle: „Business first, data second“ is the ultimate goal during trainings. The goal is to get as quick as possible to business valuable information that are in every Google Analytics account. Agenda and difficulty of training always depends on audience knowledge – we can discuss absolute basics or advanced attribution models too. What do I lecture the most?

  • What is Google analytics measurement based on? Who is user, session and interaction?

  • How the data is sent into Google Analytics and how to bend it to find out the most you need about your customers?

  • What traffic sources do we have and where do your highly converting customers come from?

  • How to set-up Google Analytics account, run the measurement and orient in interface?

  • How to filter only the information we need to know and how to understand the metrics we’re looking at?

  • We’ll show the use cases of how to work with UTM parameters, which help you to tag and evaluate the success of your online campaigns.

  • How to measure relevance and content business impact on your website: How do your landing pages or blogposts work?

  • How to measure impact of all your online activities and based on them how to set-up a marketing mix?

  • Where do you lose your potential customers? What are you weak sides of your website and how much money do you lose?

  • How does your buying process work and how much extra revenue you can get?

  • How to set-up enhanced e-commerce modul for e-shops, to find out which products are bestsellers and to know the full path from the first product impression on category list to refunds?

And there’s much more – it’s always possible to design the training exactly for your needs, to leverage the maximum for your business.
