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.

Iurii (Yurri) Iurchenko, FACHDM

I am speaking at FABCON & SQLCON – The Microsoft Fabric & SQL Community Conferences. Please check out my talk if you're attending the event!

⏱️ When? Friday, March 20, 10:10–11:10 AM in C102
☕️ What? Unstoppable Fabric: Capacity Planning, Smart Alerting, & Workload Tuning
🎯 Why? Understanding capacity is crucial for efficient and reliable use of Fabric in an organization. Unfortunately, many struggle with this due to the complexity of the capacity throttling mechanism. That's why my goal is to fill that gap by sharing mitigation strategies.

I can suggest personal consultations from CJ not only for interview preparation, but also for mindset shifting. After his consultations, it is much easier to think with a "business first" approach and feel the business goals, instead of focusing solely on the technical level

Crack FAANG+ Sr., Staff+, EM Behavioural, and System Design HLD interviews | DM me “COACH” | Engineering Manager @ Amazon | Engineering Career Coach | FAANG+ Interview Coach

You have great behavioral stories on paper. 
But you freeze when you open your mouth.

Many Staff Engineers and EMs use AI to write their career stories.

They build perfect documents. 
But they still lack confidence in real interviews.

Your problem is not a lack of stories.
Your problem is a lack of confidence to speak them.

System design interviews are objective. 
You can always fall back on technical concepts.

Behavioral interviews are different. 
They expose your soft skills immediately.

You do not need another book.
You do not need another AI prompt.

How to fix your interview confidence
- Practice speaking your stories out loud.
- Find someone to give you direct feedback.
- Get a partner who will not beat around the bush.

Stop reading your stories. Start speaking them.

If you are preparing for mid-senior/staff SDE, EM behavioural interviews, and need help, DM me COACH.
