 WORK EXPERIENCE
Project – Darts
October 2025 - current
Tech Stack: Go, gRPC, React, PostgreSQL, Redis, Docker, Python
GitHub: github.com/dimqueue/darts
A full-stack distributed word similarity game demonstrating
microservices architecture, API design, and cloud-native practices. Players try
to guess a secret word and receive semantic distance feedback powered by
machine learning word embeddings.
• Architected and deployed a microservices system with 3 independent
services communicating via gRPC protocol using Protocol Buffers for
efficient serialization
• Implemented a concurrent RESTful backend API in Go utilizing
goroutines for handling parallel requests
• Integrated Redis caching layer for compute-client requests, reducing
database load and improving response times
• Built an automated CI/CD pipeline using GitHub Actions with multi-
stage Docker containerization
• Designed a normalized PostgreSQL database schema with optimized
indexes and query performance
• Developed React-based frontend for real-time data visualization and
user interaction
• Created a Python compute client for distributed task processing

Intern – Distributed Lab
May 2025 – November 2025
Tech Stack: Go, PostgreSQL, Docker, Blockchain APIs

• Built a blockchain transaction indexing service for processing and
storing cryptocurrency transaction data
• Implemented data parsers for multiple blockchain protocols using Go's
concurrency primitives
• Optimized PostgreSQL queries with strategic indexing, reducing lookup
time by 40%

 • Integrated cryptographic validation modules for secure transaction
verification

NER System for Ukrainian Text Processing
February 2025 – June 2025
Tech stack: Python, Pytorch, GLiNER, Label Studio
Developed a domain-specific named entity recognition system for email
texts by fine-tuning GLiNER model.
• Fine-tuned GLiNER model for Ukrainian email entity extraction,
achieving 82% F1-score (vs 21% baseline)
• Built end-to-end ML pipeline: created a 250-example annotated dataset,
trained a model
• Published 2 conference papers on NER challenges and LLM approaches
• Improved key metrics: Order numbers 91% F1, Dates 85% F1, Delivery
services 76% F1
