What I'm looking for

I am looking for technically challenging roles where I can design and build scalable data/backend architectures, lead and mentor teams, and deliver measurable business impact in collaborative, outcome-focused environments.

I am a seasoned Information Technology professional specializing in backend and data engineering with over 15 years of experience in industrial and financial sectors. I combine strong logical thinking with a passion for software architecture, data platforms and practical delivery.

Throughout my career I progressed from software developer to architect and leader, delivering MES/LIMS/PIMS and large-scale data solutions for clients including banks, mining and metallurgical companies. I design and implement microservices, data engineering architectures and real-time ingestion pipelines.

I have led and built teams focused on results and professional development, creating collaborative environments and driving high-quality outcomes such as migration projects, MES rollouts and investment-data products. Recent achievements include building a robust data stack for an embedded bank and developing AWS Bedrock integrations.

I bring hands-on expertise across Java, Python, cloud-native AWS services, Apache Spark, Kafka, Airflow and CI/CD practices, and I seek roles where I can technically lead, design resilient architectures, mentor engineers and deliver measurable business value.
