About me
Backend Developer & Systems Architect based in Sofia, Bulgaria. I build cloud-native microservices and AI-powered automation for enterprise-scale systems — currently at SAP, where I architect solutions that orchestrate SAP ECC → S/4HANA Cloud migrations.
My background spans high-throughput iGaming platforms (Flutter International, Evolution), mathematical modeling, and distributed systems engineering. I work primarily in Java, with Python for tooling and automation, and have hands-on experience integrating LLMs and building AI agent pipelines.
What I'm doing
-
Java Systems Architect
Specialized in architecting robust, scalable, and cloud-native Java backend platforms optimized for high-throughput, low-latency environments in regulated, data-heavy industries such as iGaming and finance.
-
AI Agent Engineering
Designing and building AI agent pipelines and LLM-integrated systems for enterprise automation — from validation agents and MCP tooling to intelligent data workflows that reduce manual intervention at scale.
-
Mathematical Modeling
Applying advanced mathematical and statistical techniques to build quantitative frameworks for iGaming and enterprise data intelligence — probability modeling, risk analysis, RTP calibration, and migration data assessment.
-
Web Development
Building modern, responsive web applications with a focus on performance and clean UX — from full-stack Flask and React projects to static sites and interactive dashboards powered by real-time data.

Thank you for your excellent work in creating the ways strategy payout for our slot games. Your innovative approach not only improved the overall design but also laid a strong foundation that will make backend development of ways-based slot games smoother and more efficient in the future. Your effort bridges creativity with technical practicality, and it will directly support me (and the team) in building robust, scalable gamelogic for upcoming games. Thank you for making a lasting impact on both gameplay and development!

Massive shoutout for completely rewriting all payout strategy systems! Your work on wild multipliers is nothing short of brilliant — supporting multiple wilds, flexible aggregation methods, and clean configuration is a game-changer. Handling any number of wilds separated in any number of types with individual multipliers Smart Aggregation – Multiplicative, additive, max, or even custom logic he knew system is both powerful and easy to maintain The way you structured this makes it effortless to configure and opens up so many possibilities for future features. Outstanding engineering! Also, massive shoutout for building up the integrity of our team. Always speaking your mind freely contributes for acknowledging all problems without hesitations and creates a safe environment for everyone to speak up about their issues.

I want to thank you for the great work and creativity you showed when we worked together on the projects "Blow Your House Down," "Cherry Breaze," "Zombies in Love," and "Foxo the Hunter and the Golden Mystery." You have proof that there is a lot of beauty in formulas and numbers. I hope that each of these projects will become a favorite among players, so that there will be a logical conclusion and confirmation of our job well done. Thanks, guys, anyway!

I want to thank Andrey for his great contribution to every project we've worked on, especially Golden Leprechaun: Knock! Knock! Knock! which achieved great success and Platinum status. He helped me a lot with building the math balance and helped this phase pass very easily and smoothly. Not only that but he always comes up with great ideas for innovations and new mechanics, which is out of his job responsibilities. I admire his creativity and passion for making games with new modern and exciting gameplay and math models.

I just wanted to take a moment to recognize the incredible effort and thought you both put into fixing this major issue that was bugging us for weeks and for all the help and guidance in the process of figuring out what the issue could have been in the first place! Your insights, support, and quick action made all the difference - not just in solving the problem but also in improving the process for the studio moving forward. Thanks again!

Your timely support on enquiries ranging from game configuration to hand history formatting makes a real difference. Without these we would be lost in details with unclear path to proceed.

Thanks for always taking an initiative for improving our vision in long term. This award could have been only for inspiring us to be proactive and an active leaders. However, it is also for the achieved results in long term basis of what we can offer in terms of architecture. It is now improved, and I am talking not only about the buy feature and ante-bet.
