01 / 02ML engineer and data scientist in industry, freelance full-stack web developer. But the trajectory is wider: combinatorial optimization, peer-reviewed papers, distinction degrees, my own services and algo-trading, sport and volunteering.
A short list of what I can probably help you with.
Optimal schedules, routes and resource allocation under many constraints
Language-model helpers that understand plain requests and take over routine work
Answers and documents grounded in internal data and rules, not generic knowledge
Auto-sorting of letters and requests, text recognition from scans, concise summaries
Classification, quality assessment, duplicate detection and object recognition
Matching relevant content, products or learning to each user
Agents that learn to make decisions from experience — from control to strategies
Segmentation, pattern discovery and forecasts from historical data
From prototype to a robust service: integration, load, GPU acceleration
A backend as a reliable source of truth: APIs, databases and business logic
Fast, responsive sites and apps — multilingual, with their own design system
Balances, payments and strict transaction accounting with guaranteed correctness
Wiring up payments, external sign-in and third-party APIs
Upload, optimization and storage of images, galleries and viewing tools
Microservice architecture and reusable components
Containerization, deployment, encryption certificates, backups and monitoring
Scheduled scraping, schedulers and automation via browser emulation
Bots and automation for Telegram and other platforms: scheduled posts, mailouts, scenarios
From school olympiads to production Data Science.
The core professional lines run in parallel. Pick one or several tracks to see the path from different angles.
A full chronicle by track: work, projects, papers, awards, education, sport, volunteering. Filter by category; scans of diplomas and certificates are attached where they survive.
A single-page personal-brand landing: a bilingual site (RU/EN) with language auto-detection, a unified experience chronicle by category and cross-cutting track with filtering, attached scans of achievements and an embedded consultations block. All content lives in a single source; an own design system, legal pages from markdown content, connected web analytics.
A public country-segmentation web console: it describes 218 world economies (about 49 features across demographics, digitalization, economy, climate and risk) and extracts user segments and product niches. A data pipeline from open sources with a versioned incremental store; a development axis (the first PCA principal component, calibrated to the UN Human Development Index, tiers) and canonical segments (k-means) with stability checks; analytical layers — feature segregating power, an opportunity map, correlations. The backend is orchestrated by Dagster (two computation tiers: light live segmentation and a heavy recompute); FastAPI serves an immutable bundle and computes live segmentation on request with a Redis cache. The frontend is a client-side landing with a zoomable world map, coloring by tier or numeric feature, filters, a range brush, a live re-segmentation lab and analytical sections; a fallback to static snapshots when the API is unavailable. Containerization, observability, deployment.
A marketplace of business meetings for IT consulting: a client describes a task, picks a slot and format (call, online meeting, async consultation), an expert runs a paid consultation. A decoupled architecture: a static SPA frontend and a containerized async API as the single source of truth (profiles, meetings, balances, tariffs, a meeting state machine). A financial model on virtual balances with strict money invariants — Decimal, profile-row locks, an append-only transaction ledger; external authentication (Zitadel, OIDC/PKCE) and a payment gateway with self-employed fiscalization.
A site combining an artist’s digital business card and an exclusive gallery of works (the author’s image, an aesthetic exposition, lead generation with no on-site payments). A decoupled architecture: a static Next.js SPA and an isolated REST backend as the content source of truth (profile, paintings, views, purchase links), static served via Caddy. A media pipeline: intake of originals, hashing, slicing each image into three sub-versions to minimize traffic. A public gallery grid with a lightbox and view switching; a hidden admin area with group image upload, drag-and-drop view reordering, Draft/Published statuses and a draft preview. Single-admin JWT authorization with secret generation at startup. RU/EN bilinguality.

Inside — sharded multi-storage by free space, Celery task orchestration, a dedicated GPU worker, correlated subqueries over metric tables.
