Professional Summary
Backend Software Engineer with 2.5+ years of commercial experience building production backend systems
for a Prague-based forex trading signals platform—covering authentication and authorization, real-time
signal delivery, admin tooling, and algorithmic trading logic for live users.
Strong in maintainable design: Clean Architecture, Hexagonal (Ports & Adapters), and Domain-Driven
Design (DDD). Build monoliths or microservice architectures depending on product stage and business
constraints.
Ship production-ready services hands-on: application code, VPS provisioning, SSH keys, Git deployment,
Nginx, Linux, and Docker/Docker Compose.
Work in Go or Python as the business requires. On Python: SQLAlchemy ORM, async I/O when needed,
and vectorised Pandas/NumPy for batch analytics.
Use AI tools (Cursor agents, project rules) to accelerate routine work—personally direct agents for archi-
tecture and business logic when company policy allows, always review diffs, and hand-write critical paths
(auth, money, security, core domain).
Experienced in distributed systems: REST and gRPC, NATS, JWT/RBAC, PostgreSQL and ClickHouse.
English: B1—comfortable with technical reading and writing; speaking and listening actively improving.

deployment on VPS (Docker, Nginx, Linux), and CI/CD via GitHub Actions.

• Worked across Go and Python depending on the subsystem—performance-critical paths in Go (gorou-
tines, channels, gRPC, NATS), orchestration and analytics in Python (FastAPI, SQLAlchemy, asyncio,
Pandas/NumPy).

• Operated as a long-term remote contributor; references and engagement documentation available on
request.
