I am a Software Engineer and Data Engineer currently pursuing my Master's degree in Software Engineering and Digital Transformation at LUT University in Finland. With a solid foundation in Computer Engineering, I specialize in building scalable data systems, automating ETL pipelines, and exploring decentralized architectures.

I thrive on turning complex backend challenges into high-performance solutions, whether that means slashing query execution times or engineering secure blockchain systems.

Here is a snapshot of the measurable value I've delivered in my previous roles:

• Database Optimization: Cut report generation time by 40% for 100+ active users and boosted data retrieval speeds by up to 60% on Microsoft SQL Server.
• Scalable ETL Pipelines: Designed and maintained production ETL processes migrating 1M+ rows of data monthly into Snowflake, improving data accuracy by 30%.
• CI/CD Automation: Streamlined deployment pipelines using TeamCity and Octopus, increasing production deployment frequency by 50%.
• Environment Efficiency: Integrated Docker into legacy development environments, reducing configuration time by 40% and improving project delivery timelines by 30%.

• Languages: SQL (T-SQL), Python, Java, C++, JavaScript, PHP
• Data & Cloud: Snowflake, Microsoft SQL Server, ETL Pipeline Design
• DevOps & Tools: Docker, Git, GitHub, TeamCity, Octopus
• Specializations: Blockchain & Smart Contracts, Full-Stack Prototyping, System Architecture

My Bachelor's Diploma Project. A decentralized platform built for secure document notarization. It leverages smart contracts and cryptographic hashing to guarantee the absolute integrity, traceability, and authenticity of multi-party workflos.

A modern, high-performance recreation of the Moodle LMS designed to simplify course management. Built using modern, high-speed technologies to optimize user experience and eliminate legacy system lag.

A comprehensive database-driven platform modeling a global flight booking and management system for a fictional airline based out of Bucharest.

• LUTES (LUT Entrepreneurship Society): Act as a tech hackathon team member, providing 1-on-1 architectural mentorship to developer teams, translating corporate/industrial challenges into software requirements, and serving as a lead judge for full-stack prototype evaluation.
