What I'm looking for

I’m looking for a software development role where I can keep improving my communication and collaboration, focus on results, and deliver features that match client requirements with strong ownership.

I’ve built software for over 12 years, and I focus on producing results while continuously improving how I communicate and collaborate to meet client requirements. In my current Senior Software Engineer role, I’ve worked across IT and Telecom projects, delivering both backend services and AI-enabled functionality.

I’ve implemented AI pipelines in Python, including RAG workflows using LangChain for chunking, embeddings, vector databases, and LLM-driven context. I also created an AI agent phone chatbot for FanCourier using Copilot Studio, integrated with topics/entities for context detection, and deployed it to Azure.

On the Java side, I’ve delivered multiple microservices and backend modules with Spring Boot, Hibernate, and database persistence across Oracle, PostgreSQL, and SQL Server. I’ve worked with REST endpoints, Kafka event processing, Docker-based deployments to Kubernetes, and production-quality practices like SonarQube quality gate fixes—while keeping the system reliable, maintainable, and aligned with business needs.
