Senior BI Consultant

My public work is here: https://linktr.ee/4iurchenko

I am a data engineer who thoroughly enjoys my work. My primary goal is to fuel business decisions with high-quality data by building Data Platforms and Pipelines. I am fluent in Spark, SQL, and Python, which enables me to effectively focus on business problems. My target role is Data Engineering in a proactive company that requires robust data with potential for AI applications. I am very familiar with Healthcare, Microsoft Azure (and particularly Fabric), and Marketing.

📌 My EMAIL 📩: 4iurchenko@gmail.com
Please DM me when you think I can assist you as a Sr. Data Engineer in solving your data challenges efficiently. 🤝 

How can I make a difference for your company?

1️⃣ Business first. My primary focus is on how my delivery is suitable for stakeholders. Is it convenient for BA / Product? Is it accurate? Is it future-ready? What are the project's priorities and constraints? I tend to ask 1-3 critical questions before implementation. If needed, I will add a pros and cons/tradeoffs story to prevent misunderstanding. Then, I am fully committed to the results we decided on.

2️⃣ Architecting & Delivering. I have a solid grasp of fundamentals, data concepts, and diagramming. Additionally, I am fluent in SQL and Python coding. So, I can flexibly switch between coding-focused tasks and higher-level system design challenges. For example, in the morning, I plan to present the architecture diagram for the PoC in LucidChart for the new AI-driven pipeline. After lunch, I will refine the PySpark pipeline to process a dataset of over 1 billion records. Before the evening, I may investigate the production incident and document findings.

3️⃣ Drive to move things further and help others, if they need it. After you talk with me, you will feel the energy. 

THE PROJECTS AND ACTIVITIES I AM PROUD OF

➩ SQL Saturday speaker - 2x selected at a SQL Saturday in San Diego about SQL & Azure Fabric

I am a 2x half-marathoner 🏃. Daily runs are a regular part of my routine, too, as I believe motion is the foundation of a high-quality life.
