Data & Cloud Architecture
Expertise in designing and building data and cloud systems across Azure, GCP and AWS, including BigQuery, PostgreSQL, Docker, Kubernetes, CI/CD, Redis and pipeline orchestration for enterprise clients.
AI & Retrieval Systems
Deep knowledge in RAG, embeddings and vector search, chunking, rank fusion, rerankers, evaluation harnesses, tracing, agent orchestration, MCP servers, and integration with Claude and OpenAI APIs.
Backend & Web Development
Proficiency in Python, TypeScript, SQL, Solidity, Rust, Node, FastAPI, React, Next.js and Prisma for building full-stack and on-chain products end to end.
ETL & Data Pipelines
Experience building ETL tools that generate and apply SQL transformations automatically, with scheduling, reprocessing and failure handling, reducing end-to-end processing time by approximately 85%.
Blockchain & On-Chain Development
Hands-on work with Solidity smart contracts, subgraph indexers, zkVM execution layers in Rust, AMM contracts, zkSync deployments and arbitrage bots for DeFi and on-chain settlement use cases.
Distributed Processing & Big Data
Academic and practical background in distributed processing using Spark, Kafka and Hadoop, as well as information retrieval techniques including ranking, embeddings, evaluation and ML statistics.
Mobile & Frontend Development
Development of mobile applications for Android and iOS using Flutter and Firebase, as well as frontend work with React and Next.js.
Team Leadership & Project Management
Experience hiring and leading engineering teams, managing planning, priorities and releases for multi-person projects, including a football score-prediction product with over 120,000 registered accounts.

Project history
Builds AI, on-chain and full-stack products for clients end to end. Recent projects focus on retrieval and evaluation: search systems over large multilingual corpora, ETL and data pipelines, evaluation and observability tooling, and agent systems with MCP integrations. The largest project was a football score-prediction product with 120,000+ registered accounts and 3.2M+ predictions. Also includes on-chain work with zkVM execution layers in Rust and DeFi contracting in Solidity and TypeScript.
Spent two years inside a client delivery team on national-scale telecom data. Built a tool that generates and applies SQL queries automatically, plus scheduling, reprocessing and failure handling. End-to-end processing time fell by about 85%. Stack: Python, SQL, GCP, BigQuery, Azure, Docker, CI/CD.
Started on full-stack product development in an Agile team using React and Java microservices. Moved to a second project with Novabase on the blockchain team: data pipelines and analytics on AWS and Azure over on-chain data, and client integrations in the energy sector including Energy Web.
