Backend Engineer — Go

Building systems that are scalable.resilient.observable.built to last.

Backend Engineer with 8+ years of experience (since 2018), four of them building cloud platform products in Go at a national cloud provider — CDN, container orchestration, and a private Docker registry. Strongest on infrastructure and operations: Linux server administration since 2015, hands-on data center work, and self-hosted on-premise systems deployed and operated end to end. Built and run two production Go platforms, including a multi-tenant PaaS on K3s, and author of open-source developer tooling in Go. Comfortable with microservices and event-driven architecture. Kubernetes at a working level — namespaces, NetworkPolicy, quotas and day-to-day cluster operations; cluster internals are still developing.

Highlights

8+ years building and operating backend systems, from national-scale infrastructure to multi-tenant SaaS.

Go in production since 2022 — backend services, microservices and distributed systems; four years of core cloud platform products at Cloudeka.

Built and runs two production Go platforms, including a multi-tenant PaaS on K3s.

Ships LLM-backed features to production — provider-agnostic, bounded, and safely degrading.

Author of open-source developer tooling in Rust and Go, including a diagram engine published on crates.io.

Four years building cloud platform products at a national cloud provider — CDN, container orchestration, and a private Docker registry.

Integrates payment gateways in production, with extensive hands-on DOKU experience — and builds the billing flows around them: top-up, balance, subscription, renewal.

Goes below the cloud: runs on-premise infrastructure and has operated servers hands-on inside the data center — setup, 24/7 monitoring, and hardware troubleshooting.

Multi-tenant PaaS where users deploy ready-made applications onto a Kubernetes (K3s) cluster through a web panel, without touching Kubernetes directly.

Tenant isolation per Kubernetes namespace with NetworkPolicy, ResourceQuota, and LimitRange enforced per subscription plan.
Single-gateway security model: only the BFF API is public and JWT-authenticated; orchestrator and DNS services stay internal behind BasicAuth.
Tag-driven CI across six repositories, with every significant technical choice recorded as an ADR.
Live billing covering top-up, balance, subscription, and renewal via payment gateways.

Life planner for routines and habits, plus Company Planner — a project-management suite — both behind a shared SSO across the domain.

Life Planner: routine and habit planning with AI assistance — suggesting plan categories, flagging vaguely-named tasks, and generating plan drafts asynchronously.
Company Planner (kanban.go-routine.com): Gantt timelines, Kanban boards, yearly planning and feature tracking, with a Butler-style automation engine (trigger → conditions → actions) and an Android client.
MCP server for AI agents: boards, tasks and projects exposed over the Model Context Protocol — an agent can read the board, create and move cards, and reschedule work through a typed interface, authenticated by service-account machine credentials.
LLM integration: typed judgments returning calibrated probabilities consumed directly by application logic, provider configured per deployment with none hardcoded, and safe degradation when unconfigured.
