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

As of a Senior Data Engineer / Tech lead, my primary goal is to fuel business decisions with high-quality data by building Data Platforms and Pipelines in Azure Ecosystem, including Microsoft Fabric. I am fluent in Spark, SQL, and Python, which enables me to effectively focus on business problems. I have a deep expertise in Healthcare and Marketing business domains.

📌 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
➩ Healthcare Analytics on Azure.
➩ Gaming data warehouse - petabytes of data + incredibly insightful driving data platform with business metrics.
➩ 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.

Hi everyone! I’m seeking a new role and would appreciate your support. If you hear of any opportunities or just want to catch up, please send me a message or comment below. I’d love to reconnect. #OpenToWork

Here is what I was able to accomplish in 4 years working for Oasis and Repario:

2. Released 40TB of disk space storage by identifying unneeded database files and #backups
3. Saved $18K/month on #virtualization costs by identifying underutilized servers that could be #consolidated or retired
4. Automated #DBA operations to manage 9K databases, avoiding 2-3 additional DBA hires (~$30K/month)
5. Stabilized the existing environment to reduce the number of P1 and P2 incidents by 80%
6. Reduced time-to-provision access from hours to minutes by automating and standardizing permission grants
