👋 Hi, I'm Alexey Shumkov

Backend-leaning Java developer who enjoys building clean APIs, modular services, and automating all the things.
Currently mastering Spring, messaging, and deployment workflows — and having fun along the way.

typing intro


🔧 Tech stack — what I use day-to-day

skills


🧭 A few quick facts

  • I enjoy designing clean REST APIs, layering services, and writing tests that make refactors painless.
  • Comfortable with event-driven pieces (Kafka/RabbitMQ), JWT/Keycloak auth, and containerized deployments.
  • I also tinker with Python/C# for coursework and small tools when it fits the job.

🛡️ Coreshield — commercial project

I’m currently building Coreshield, a Telegram-based VPN subscription service bot (secure payments, automated key delivery, simple onboarding & support).
Try it here: https://t.me/coreshieldvpnbot


🚀 Projects I’m proud of (highlights)

Short and sweet — here are a few representative ones.

  • Forum-Microservices-Backend — multi-service forum with Spring Boot, PostgreSQL, MinIO, Reactive Kafka, WebClient, Mail, JWT.
  • Noname-bank — team project: multi-service banking sandbox (auth, gateway, notifications, user service, etc.).
  • KartoshkaWallet — a wallet backend (2-week intensive): Spring Boot, PostgreSQL + Flyway, JWT, Prometheus + Grafana, Docker.
  • Campus-Course-System — backend for campus courses (roles, courses, applications) with Spring Boot + JWT + PostgreSQL.
  • Delivery-Backend-App — course backend in C#/ASP.NET Core + EF + PostgreSQL + JWT.

Open to teaming up on backend/microservices work.
You can also peek at my Organizations for team projects (e.g., IbraTeam, HITS Internship system).
