I can help you with:

- Quick prototyping and creating your MVP/PoC. I use a variety of technologies, allowing me to cover a lot of use-cases: from Streamlit for data-centric apps to Phoenix LiveView for delivering apps that feel like SPA but are much faster to build and easier to support. I'm full-stack, and can help you with onboarding developers and expanding your team over time.

- Integrating AI/LLMs/Agents and traditional machine learning into existing products. In fact, I have an AI powered product of my own:

- Cloud architecture, cost optimization, DevOps, DevEx, and software architecture work. For example, if you need to make your app faster, reduce the amount and severity of bugs, or optimize your cloud costs. I love Kubernetes, run my own infrastructure for my own projects, and can recommend low-effort solutions if you don't need/want to have a separate operations team.

- Building data-intensive applications and optimizing existing data systems. I'm good with SQL, Spark, Airflow, Pandas, and worked with a variety of big data systems over the years: Snowflake, Redshift, BigQuery, Foundry, etc.

I've been programming for 20+ years, 10+ of them professionally, and have 5+ years of technical leadership experience. I usually work with the following tech stack: Python, Elixir, Rust, Kubernetes/Docker/AWS/Fly.io/Hetzner, PyData/Keras/LangChain, PostgreSQL/Clickhouse/OLAP.

I also run an educational YouTube channel with videos about Rust, Elixir, algorithms, and data structures: youtube.com/c/modernRetroTech. Sometimes I write in my blog:

Head Of Engineering
E-COMMERCE
April 2022 - October 2022 (6 months)
Berlin, Germany
I worked part-time as a head of engineering to help build data & engineering systems, introduce engineering culture and practices, and to hire the base engineering team.

Some of the projects I completed for the company:

- Delivered first dashboards in my first week
- Developed a deployment system, CI/CD, setup infrastructure: this allowed newly hired team members to deploy their code without any additional setup. The system also has a functionality for automatic setup of development environments, which allowed data scientists in particular share their results as they were becoming available and work closely with non-tech stakeholders.
- Using graphical design from an external contractor, I implemented and load tested the landing page of the company that successfully handled spikes in traffic when the startup went out of stealth.
- Implemented an internal system for managing incoming leads and automating various acquisition process steps.

September 2020 - March 2022 (1 year and 6 months)
Berlin, Germany
As a head of data, I hired & trained a team of a product manager, 2 data engineers, 3 data analysts, and 1 BI analyst. Established culture of autonomy & ownership in the team.

Designed & implemented the first version of a new data app with Streamlit-based dashboards, to allow for continuous maintenance & development of those dashboards by data analysts.

Together with the data engineers, designed and introduced proper test / staging environments, CI/CD, and refactored the system to a monorepo containerized service oriented solution.

Introduced new data analytics workflow based on Jupyter notebooks, PyData, and Git, speeding up data analysis projects and allowing us to reuse metrics & computations across those.

Together with the rest of the management team, I introduced OKRs for the company & my department. Me and my product manager developed new product management flows based on ideas from Shape Up and Amazon's PR FAQs, reducing stress for the team and improving our velocity and focus.

I highly recommend recommend Dmitrii for his exceptional work in rebuilding our data pipeline. As a skilled data engineer, he utilized new smart approaches that improved the speed and efficiency of our data queries beyond our expectations.

In addition to his technical expertise, Dmitrii has been an excellent communicator throughout the project, keeping our team informed and involved in the process. His professional approach made it easy for us to understand the changes he implemented and the impact they had on our data processes.

Furthermore, he consistently demonstrated his ability to think outside the box and find alternative solutions to any challenges that arose.
His strong work ethic, extensive technical knowledge, and excellent communication skills are valuable assets that he brings to any team

I've been working as a direct report with Dmitrii for 2 years at Lana Labs, and it has been a great experience. Not only is Dmitrii very knowledgeable across all layers of a modern application stack, he also makes sure to coach others around him. Under his supervision, I was able to greatly strengthen my skills & deliver some of my best work. I highly recommend working with Dmitrii & am sure he will have a long term positive impact on your project & team.
