PROFESSIONAL SUMMARY
TypeScript developer who builds internal business systems end to end for a manufacturing company: Node.js (NestJS) APIs
and background jobs, React and Next.js interfaces, and PostgreSQL with row-level security and audit. Delivered a
deal-management system that brought 160,000 chat messages and 20,000+ customer records into one place, and a
warehouse module for an MES that takes over 1C functionality, with a tablet scanner interface and role-based access. Write
the specification, design the architecture, cover the code with automated tests (2,000+ in the largest project) and ship
through CI and Docker. Use AI tools under my supervision: I set the context, review the output and verify it with tests.

PROFESSIONAL EXPERIENCE
JUNIOR SYSTEM ADMINISTRATOR 2026 - Present
Moni LLC (cosmetics and medical products manufacturer) | Uzhhorod, Ukraine
• Developed the company's internal software (see Projects), from technical specification and architecture to automated
tests, CI and deployment.
• Administer Windows and Linux (Ubuntu) servers, PCs, the network, mail, 1C and KeyCRM, and manage user access for
about 100 employees.
• Handle employee support requests of any complexity, from PC, network and mail issues to access problems and failures
in servers and business systems.

PROJECTS AT MONI LLC
IMS | Internal System for Managing Blogger Partnerships 2026
• Developed IMS, which collects Telegram and Instagram conversations in one place, tracks deals through a 15-stage
pipeline (kanban and table views), generates contracts from HTML and Word templates and syncs with KeyCRM and a
Google Sheets tracker. Messages are always sent by managers.
• Integrated several corporate Telegram accounts (live sync of new, edited and deleted messages, replies from IMS,
catch-up after downtime) and Instagram through the Meta API with OAuth and webhooks. Background jobs run on
BullMQ and Redis with API rate-limit handling.
• Imported chat history (~1,500 conversations, 160,000 messages) and migrated 20,000+ customer cards from KeyCRM.
• Built AI features: the system detects the deal stage, extracts terms (price, format, dates), reads photos, voice messages
and documents and filters out non-target chats. It learns from manager corrections, and card and passport numbers are
masked before data goes to the model.
• Implemented role-based access (manager, lead, admin), 2FA by email, brute-force protection, encrypted secrets, request
rate limiting, an audit log, and analytics with CSV export. Covered with 2,000+ Jest tests; deployed with Docker
Compose and nginx.
Tech: Node.js, NestJS, TypeScript, PostgreSQL, Prisma, Redis, BullMQ, MinIO, React, Vite, Tailwind CSS, Vercel AI
SDK, Jest, Docker Compose, nginx, Nx, pnpm

MES | Finished-Goods Warehouse Module 2026
• Developed the warehouse module of an MES project that takes over 1C functionality: wrote the specification, designed
the architecture, interaction with other departments and dependency logic.
• Implemented the logic in PostgreSQL (PL/pgSQL, Supabase) with audit and row-level security, a role and position
hierarchy, user management, the wholesale order flow and work-time tracking that replaced a Google Form.
• Built a tablet and Android scanner interface. Covered the code with Vitest tests, set up CI in GitHub Actions and
deployment to Vercel. Developed with AI tools under my supervision.
Tech: TypeScript, Next.js 16, React 19, Supabase/PostgreSQL, TanStack Query, Zod, Tailwind 4, shadcn/ui, Vitest,
GitHub Actions, Vercel
StoreChecker | AI Price Tag Recognition 2026
• Developed StoreChecker: Gemini reads price tags from photos, and the user confirms the result before it is matched with
MySQL tables, so recognition errors do not reach the data.

OTHER PROJECTS
MALY RYATIVNYCHOK ("LITTLE RESCUER") | AI Support Bot 2025 - 2026
• Built a Telegram support bot on the ChatGPT API (Python, SQLite): it classifies the topic of each request and emails a
specialist when alarming markers appear. Extended it into a web platform.
FIRE THE LIGHTS and BETTER BE ALONE | Solo Game Developer 2026
• Released two Unity (C#) games on itch.io (manykywi.itch.io): a 2D survival-strategy and a first-person PS1-style horror.
Developed with an AI assistant under my close supervision.
• Covered them with automated tests: end-to-end pytest + Playwright on the WebGL build, and 84 PlayMode tests with a
performance benchmark.
