01

Product portfolio and development cluster leadership

Innotech (T1 Group) · December 2025 — present

Challenge

Several products and cross-functional teams need to operate as one system while business priorities, product backlogs, architecture, resources, and dependencies change at the same time.

Action

Built the portfolio and cluster operating model: connected business needs to the roadmap and product and technical backlogs; aligned budgets, resources, timelines, risks, and cross-team dependencies.

Result

Average time to market for product changes is 14 days. After the offer calculation and formation strategy was redesigned, the share of offers that ended in a completed banking product application increased by 30%. The estimated portfolio impact is several billion rubles.

02

Decision Engine — a SAS RTDM-class product in 5 months

Innotech (T1 Group) · late September 2024 — April 2025

Challenge

The bank needed its own Decision Engine for real-time personalized offers, with production-grade reliability, scaling, and processing of tens of TB of data per day.

Action

Took over the project as IT Lead in late September 2024 and formed the team by November. In December, already serving as Project Director, I started development and established the full engineering process: requirements, architecture, development, testing, CI/CD, releases, and operations.

Result

The product entered production in April 2025, five months after development started. Its real-time and batch pipelines run on Apache Flink, Tarantool, and Kafka.

03

IT Lead of Big Data application services — automation from 40% to 80%

Innotech (T1 Group) · March 2023 — September 2024

Challenge

Specialists from the graph and geo platforms, NER services, and ML data labeling did not yet operate as one team. A shared process had to be established amid legacy migrations, technical debt, and fragmented CI/CD standards.

Action

Brought the specialists together as one team and established the engineering process. Moved CI/CD toward one TeamCity pipeline, completed critical migrations, and built resource management. Initiated the technical expert community across T1 Group that became the Tech Guilds.

Result

Automation up from 40% to 80% within the information system. Cut technical debt almost in half, and cleared the critical information-security and support issues.

04

Mirion — from graph platform to product

Innotech (T1 Group) · August 2021 — February 2023

Challenge

The VTB graph platform needed to become the Mirion product, connecting data, ML/AI, and graph-analysis work with a coherent product architecture.

Action

I prototyped ETL and ML/AI solutions, researched graph algorithms, and helped shape the product architecture. From May 2022, I led the analytics team and reviewed the main data flows.

Result

The platform gained a product structure as Mirion. By February 2023, my scope had expanded to deputy IT Lead responsibilities and resource management.

05

Tech Guilds — 1000+ cases, 20+ experts

Innotech (T1 Group) · March 2023 — November 2024

Challenge

Architecture practices lived in silos. Teams kept reinventing the same solutions across different products, technical debt kept growing, and there were no shared standards.

Action

Initiated and launched the Tech Guilds community: formed a core of 20+ experts, secured support from the group leadership, and built shared standards and cross-team knowledge exchange.

Result

The community solved 1,000+ engineering cases and spread shared practices across teams. Data Engineering and systems analysis courses were launched.

06

Kerama Marazzi (Mohawk) — Data Governance for US investors

Kerama Marazzi / Mohawk Industries · June 2019 — September 2020

Challenge

The holding’s data architecture (reference and master data) was fragmented. Daily reporting to US investors in the parent group was breaking down.

Action

Designed the data architecture and defended an adapted Data Governance project before top management — my first hands-on project management. Rebuilt the data flows on a waterfall model within the parent company. R&D on local ML models (pymorphy2, K-Means).

Result

The solution scaled across the entire holding in Russia. The daily-reporting issues for US investors were resolved and operational risk dropped. Stack: Python, SQL, Pandas, NumPy, Seaborn, MS Visio, 1C (DO, KORP, ZUP, UPP, UT).

07

LAF — an engineering-management system with AI agents

Personal product · in active use and development

Challenge

When several products are developed in parallel, process consistency, decision context, and quality controls are easy to lose, especially when AI agents participate in delivery.

Action

Built a system that defines roles, stages, artifacts, and mandatory quality gates. LAF records decisions and helps move each product through one consistent engineering lifecycle.

Result

I use LAF in my own projects and continue to develop it. The product remains private, and I am considering commercializing it.

08

Talks — HighLoad++, Analyst Days, Analysis & PM Conference, Impulse

Personal · speaker · 2022 — present

Challenge

Real-world cases on real-time, data, and engineering management are poorly documented in the Russian-speaking community — every team reinvents the same mistakes.

Action

Talks at HighLoad++ Saint 2024 ("Moving a Banking Product to Real Time"), Analysis & PM Conference 2024 ("Building an Expert Team", "Accelerating Development with AI"), Analyst Days 15 (2023, "Behold, Padawan: the Path of Data"), Impulse 2023 ("Community Synergy"), and Analyst Days 14 (2022, "Don’t Paint the Grass — Data Risks in a BANI World").

Result

Built a sustained speaking record at major technology conferences. The HighLoad++ Saint 2024 talk is available on the HighLoad Channel on YouTube.

09

Dev Planning — planning a large team in minutes

Personal product · author

Challenge

A leader needs to assess a large backlog quickly and understand who can do the work, in what order, and by when. Capacity, skills, and dependencies make manual planning cumbersome.

Action

Built an assistant that accounts for team composition, capacity, dependencies, sprints, and the company’s configurable engineering process, then assigns work across specialists.

Result

Within minutes, Dev Planning turns a large backlog into a reasoned team plan that can be recalculated as priorities and available capacity change.
