Senior Software Engineer

I build the technology that helps your business grow.

Hi, I’m Filip. With 13+ years of experience in Java, Spring Boot, SQL, Kafka, and a variety of other software tools and technologies, I help companies turn complex technical challenges into smooth, reliable software.

Reliability

13+ years of building systems that don't break.

Clarity

I explain complex tech in plain language.

Scale

Expertise in Java & Kafka for massive growth.

Proven Results

A selection of projects from 13+ years of engineering across critical industries.

Java, Spring Boot, PostgreSQL, Redis, Kafka, OAuth2

Task Management Architecture

"Result: Enterprise-grade reliability."

I developed a highly secure, scalable task engine. By implementing Redis for caching and Kafka for asynchronous events, I ensured the system could handle complex workflows while maintaining peak performance and user security.

Productivity / SaaS
Java, Spring Boot, Redis, MongoDB

Time Tracking System

"Result: High-precision data processing."

I built a high-speed tracking system designed for millisecond accuracy. Using a combination of Redis for fast lookups and MongoDB for flexible data storage, the platform handles massive streams of activity data without lag.

Time Tracking / SaaS
Java, Spring Boot, Akka Streams, MongoDB

Banking & Finance Core

"Result: High-volume transaction processing."

I engineered reactive backend systems to manage heavy financial data flows. By leveraging Akka Streams, I ensured that high-volume transactions were processed with extreme resilience and consistent zero-downtime availability.

Fintech / Payments
Java, Spring Boot, Oracle, OpenShift, Kafka

Telecom Modernization

"Result: Monolith to Microservices migration."

I led the strategic migration from a restrictive monolith to a flexible microservices mesh. By utilizing OpenShift for cloud-native deployment and Kafka for inter-service communication, I improved system agility and reduced maintenance overhead.
