Work Experience
CTO
Argmin AI
- Built and shipped Judge Builder, a guided tool for creating and calibrating LLM-as-a-judge evaluators from examples and expert feedback.
- Developed the Argmin AI platform to evaluate LLM applications, compare quality and cost across versions, and support cost-optimization decisions.
- Designed Argmin AI's optimization engine to reduce LLM inference costs by 2-5x through smarter model choice, prompt strategy, and routing.
ML Team Manager
SuperAnnotate
- Managed an international, cross-functional team of 3 ML engineers and one product manager, focused on productized delivery of annotation and evaluation tools.
- Launched automatic annotation tools for images, videos, and text, helping regain feature parity with competitors and significantly reduce manual labeling effort and turnaround time.
- Built semantic data curation features using embeddings (BLIP, OpenCLIP, and PyTorch metric learning) and OpenSearch vector DB, enabling users to manage datasets more effectively and manually select similar objects for labeling or review.
- Developed LLM evaluation pipelines using DeepEval and DeepTeam, including LLM-as-a-judge scoring with integrated guardrails, automating QA workflows, and improving customer confidence in label quality.
- Created agentic pipelines for pre-annotation using automatic and semi-automatic feedback loops, improving annotation accuracy and reducing human-in-the-loop load.
- Established an MLOps pipeline in collaboration with SRE and QA teams using AWS, MLflow, and Jenkins, automating quality checks and reducing deployment overhead.
- Led internal research on detecting AI-generated text and identifying impactful fine-tuning samples for non-STEM datasets, resulting in a benchmarked model published on Hugging Face using TRL, PEFT, BitsAndBytes, Ollama, and DeepEval.
Risk Modeling Team Lead | Manager of ML Engineering
Bank Dom.RF
- Managed and monitored a team of 5 risk-oriented ML engineers.
- Introduced bureau-based credit scoring models for individuals, entrepreneurs, and SMEs, enabling data-driven loan approval and improved risk assessment across multiple client segments.
- Designed and launched a real estate scoring service for B2B clients, automating creditworthiness evaluation for construction and property companies and reducing manual review time.
- Delivered a cash-flow forecasting model for mortgage securitization, improving portfolio transparency and supporting risk-based pricing decisions.
R&D Team Lead
Sberbank
- Managed a hybrid product plus research group of 6 data scientists and 5 engineers, adapting bleeding-edge NLP/CV (Transformers and BiLSTM) to enterprise use cases.
- Built an NER service for legal documents used in the online loan pipeline, enabling Sberbank's "Seven Minutes" decisioning for large corporate loans that previously took 7 days.
- Designed and shipped Digital Manager, an email and document assistant that recommended correct actions in 90% of routine executive cases.
- Built delegation recommendations for the Digital Manager, suggesting effective delegation schemes in 75% of executive workflow cases.
ML Engineer
Mail.ru Group (myTarget)
- Improved CTR prediction by incorporating user clickstream and session features into ranking models, enhancing ad relevance for banner placements.
- Supported deployment of a C++ CTR prediction service for high-load ad ranking, helping move model improvements into production banner placement workflows.
- Analyzed how search-session context, banner context, and user click history influenced click relevance, informing feature design for CTR ranking models.
Software Engineer
KB Panorama
- Contributed to a navigation system for cargo vessels, implementing features and fixes across routing, UI, and data processing modules.
- Optimized vessel-routing algorithms reduce the time required to calculate routes for cargo-ship navigation workflows.
- Fixed bugs across routing logic, user interface behavior, and data-processing components, improving the reliability of the navigation system.
