I joined the team to help build an in-house e-invoicing platform for Clearfacts, designed to streamline and simplify their invoicing processes. With the contract approaching its conclusion, we successfully delivered a fully integrated platform, covering all core functionality in record time. This platform now enables Clearfacts to manage customer records, create invoices, and handle credit notes efficiently—all within a custom solution tailored to their needs. My role in developing and launching this product was key to achieving a rapid, high-quality delivery that met the client’s goals.As a Backend Developer specializing in Go, I played a pivotal role in building the core functionality of a high-performing SaaS e-invoicing platform. Leading the backend design and development, I helped create a scalable, event-driven architecture that seamlessly handles complex operations, including customer management and e-invoice generation. My work enabled us to deliver key product features on time and exceed expectations, establishing a strong foundation for future growth.

Bleenco is a German startup, where I helped shape a complex SaaS solution designed to make AI/ML model development and sensor data processing seamless for engineers. This platform allowed users to build complex workflows through an intuitive, low-code UI, all while maintaining real-time data processing with minimal latency.When I joined, the backend codebase needed substantial improvement for readability, maintainability, and efficiency. I focused on optimizing and reorganizing the core code, creating robust structures that allowed for faster, error-resistant communication between microservices, and developing efficient data access patterns that ensured data integrity. Additionally, I built out features like real-time statistical insights for clients, allowing them to understand user needs better and improve their own processes.My contributions played a significant role in enhancing product stability and scalability, which helped the startup secure a major investment. Although I eventually left due to relocation requirements, the platform’s success and the positive reception from investors highlighted the impact of our work.

In my first role as a Go developer, I contributed to transforming a high-load, monolithic PHP application into a scalable microservices architecture. Tasked with handling a significant volume of requests per second, this project introduced me to the aspects of high-load system design and efficient resource management. As a junior developer, I worked on key components to ensure stability and responsiveness while learning how to decouple services for improved performance and scalability. This experience gave me hands-on knowledge in transitioning from monoliths to microservices, laying a solid foundation for future work in high-performance, distributed systems.
