Backend expertise
I like systems that are boring in production: observable, secure, tested and easy to evolve.
Distributed systems
Microservice architecture, API gateways, vendor integrations, messaging, data consistency and operational failure analysis.
Observability
Metrics, traces and logs with OpenTelemetry, Prometheus, Tempo, Loki and Grafana dashboards for real production diagnostics.
Open-source projects
Small, practical tools created to improve everyday backend development workflows.
Jvim
A Neovim-based Java development environment focused on terminal-first productivity, LSP support, formatting, Treesitter and a clean Java workflow.
jvim-docker
Containerized development setup for Jvim, designed for reproducible environments and remote terminal-based work.
What I work on
A compact view of the engineering areas I keep returning to in real projects.
Backend
Banking backend and microservices
Designing and supporting backend services, API integrations, authentication flows and production-facing reliability improvements.
Integration
Vendor and platform integrations
Building integration flows, gateway endpoints, request/response mapping, retries, error handling and secure communication between systems.
Observability
Diagnostics and reliability
Building dashboards, PromQL queries, trace/log correlation and practical tools to debug latency, timeouts and inter-service failures.
Tooling
Developer productivity
Creating a focused Java workflow around Neovim, Docker, LSP, formatting and terminal-first development habits.
