What I'm looking for

I’m eager to take on challenges and support development teams with leadership and guidance across product development efforts, using technology and automation to eliminate inefficiencies and make better use of available information.

At MINOTORE, I guide backend development for a SaaS platform serving financial market players. I combine hands-on system design and development with technical direction, helping deliver robust, scalable, and secure solutions.

As a Java Backend Engineer at MINOTORE, I designed and implemented Spring Boot microservices for banks, asset managers, and trading companies. I also transitioned the system to native builds with GraalVM and deployed services to Azure using Docker.

During my MINOTORE internship, I built a BERT-based financial question-and-answer system and integrated it into a RESTful API microservice. I also built an NLP-based advanced search engine with a recommendation system.

Earlier, I built a Python test simulation framework with ECU for Porsche engineering company's cars, and developed data and machine-learning projects involving recommendation systems, prediction, and analytics. My background spans backend engineering, data engineering, and machine learning.
