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
➩ 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.

Avenga

As a Senior Software Engineer at Avenga, the focus has been on driving impactful changes through innovative software solutions. Designing and implementing new features has not only enhanced user engagement but also streamlined application functionality. This effort resulted in a notable increase in user satisfaction scores by 25% within just six months of deployment. 

Optimizing API endpoints was another key area of contribution; by employing caching, pagination, and response compression techniques, latency was reduced by an impressive 40%. This optimization significantly improved performance for over 10 million API consumers. Additionally, introducing asynchronous processing with RabbitMQ and Kafka allowed the system to efficiently handle up concurrent requests while boosting overall system throughput by 35%.

Analyzing database queries led to a remarkable achievement of reducing query execution time by 30%, which translated into faster application response times and an enhanced user experience. Resolving critical production issues under tight deadlines ensured minimal downtime; this commitment maintained a stellar uptime rate of 99.9% during peak operational periods. Mentoring junior developers has been equally rewarding as it fostered their professional growth within the team.
