Expanded payment options by 50% through scalable integrations (PayPal, Klarna, SEPA). Reduced fraud by 70% through secure merchant agreement flow applied across all payment methods. Achieved 100% regulatory compliance by proactively updating middleware to align with Visa/Mastercard specifications. Modernized CI/CD pipeline, reducing deployment times by 75% and cutting production bugs by 50%. Involved in migration to AWS and transition to a microservices architecture using Docker, Kubernetes, and Ansible.

The client, leader of complex migrations industry, was struggling with unpredictable release cycles of its product, unmaintainable code base and incomplete development processes. • Ensured quick and reliable CI/CD pipelines by enforcing modern development techniques and aggregating third-party tools. • Ensured 100% stability of the application by dropping the vulnerabilities by 65% by improving code quality and enforcing code reviews.

Client had a very slow-moving process when hiring new developers or partners due to the lack of transparency of a poorly maintained code base. • Drastically decreased onboarding time from 1-2 weeks to only 2 days by designing a brand-new well-documented API framework to facilitate messaging between the application components. • Ensured a rock-solid infrastructure by decreasing development time by 70% by aggregating the standard practices and patterns into a highly intuitive framework.

A large pharmaceutical company was struggling with maintaining a different content management platform for storing vital documents after it purchased a company and its data. • Successfully designed and proved a high-reliable migration pipeline by transferring 100% of essential data from the source platform by mapping metadata between the old and new system with high accuracy and optimal resource usage.

The client, a leader in content migration industry, had considerable annual losses due to missing integrations with important content management systems. • Successfully increased the revenue with over €1M by leading a fast-paced team of 3 developers to develop reliable and high-performant algorithms. • Ensured a 3x faster content migration process than using conventional approaches by designing a data gatherer and aggregator components to handle metadata and content.

A medium-sized pharmaceutical company struggled to move its data from a no-longer-supported on-premise platform it had to a cloud solution to reach the industry standard easier. • Successfully reduced migration costs by 45% and decreased the migration duration by 60% by designing a robust migration pipeline by ensuring complete and fast-paced content and metadata transfer to a third-party cloud platform without downtime on the on-premise source system.

The client was dealing with enormous maintenance costs while trying to keep his content management platform up-to-date against the new industry rules, which were changing yearly. • Drastically reduced the maintenance costs by 60% by implementing a solution based on a low-cost content management platform by using a different release cycle approach to meet the new volatile changes in the industry.

The client, a large pharmaceutical company, had issues while keeping track of its physical storage elements in the newly built warehouses. The application had to be integrated with existing hardware available on-site. • Drastically decreased the tracking costs by 75% by implementing solutions to automate existing operating procedures fully. • Successfully integrated 100% of existing hardware into the management platform by designing a solution to handle barcodes using dedicated devices.

The client was facing issues while trying to upgrade his base content management system because the custom solution he had on top of the initial version was no longer compatible with the newly implemented one. • Successfully launched the new version with his custom code by ensuring 100% compatibility by aligning the solution to modern quality and performance standards.
