Summary Engineering Projects
Software Engineer focused on building I have hands-on experience developing personal
and deploying concurrent backend pet projects, including designing, implementing,
systems and REST/gRPC APIs using deployment with Docker and maintaining
Go. Strong foundation in Linux backend applications. Through these projects, I
environments, containerization with gained practical experience with modern
Docker, CI/CD workflows, and technologies, problem-solving, and software
database management. Passionate development workflows.
about automation, infrastructure grpcsso – gRPC SSO service designed for
reliability, and developer tooling. centralized authentication using jwt
sessions.
Tech Stack carrpigeon - Email notification service with
Go, Nodejs, Bash templates support.
SQLite, PostgreSQL, Redis seaurl – Simple and fast URL shortener.
Netwoks & Protocols (TCP, HTTP, memap - Concurrent in memory cache
TLS, DNS etc.) (Redis alternative) written in Go.
REST, gRPC Key Engineering & Architectural
SDLC, Jira Achievements:
Git, GitHub, CI/CD GitHub
Lock-Free Concurrent Architecture —
Docker, Linux(user managment, designed a system where each shard
files & permissions, processes maintains its own RWMutex, allowing parallel
etc.) goroutines to operate on different shards
without contention for whole map.
Soft skills Sharded Map with Lock-Free Access —
Communication & Collaboration developed a distributed data structure with
n**2 shards using FNV-32a hashing to
Self-Management
minimize contention and maximize
Adaptability & Continuous Learning throughput under concurrent workloads.
Technical Translation Namespace Manager for Logical Isolation —
Problem-Solving & Critical Thinking implemented namespace management
system enabling data isolation for different
Education applications/users within a single cache
2024 - 2028 instance.
gRPC Server with Proto-Based API —
National Technical University of developed type-safe gRPC API using
Ukraine “Igor Sikorsky Kyiv Polytechnic Protocol Buffers and proto-validation to
Institute” prevent invalid requests at framework level.
Bachelor of Software Engineering JWT Token Manager with RSA Encryption
— developed a comprehensive JWT token
Languages management system supporting both access
and refresh tokens with asymmetric RSA256
Ukrainian (Fluent)
encryption.
English (Intermediate) Two-Level Caching Architecture —
implemented Redis-based cache layer for
roles and permissions with PostgreSQL
fallback, significantly reducing database
queries.
