Experience

chitchat.gg — Software Engineer (Infra, Backend)Jan 2026 – Present

• Operate a production k3s cluster: application deployments, rolling upgrades, and autoscaler configuration. • Led a zero-downtime ingress migration to Kubernetes Gateway API, ahead of nginx-ingress deprecation. • Built a full observability stack with self-hosted SigNoz and OpenTelemetry, including service dashboards, infrastructure alerts, error-rate tracking, trace sampling set to reduce cost, and custom metrics for real-time connection tracking across rolling deployments. • Migrated production k3s cluster from DigitalOcean to Hetzner Cloud, cutting monthly infrastructure costs by ~50%. • Set up GitHub Actions CI/CD pipelines: automated container builds, image pushes, Helm-based deployments, and PR preview environments. • Automated database backup and restore pipelines with scripted tooling for large collections and resumable execution.

Chainstep GMBH — Backend Service DeveloperJul 2021 – Jan 2026

• Built and ran microservices (Node.js, TypeScript, Go) for an NFT marketplace, including service boundaries, communication between services, and deployment layout. • Built GitHub Actions CI/CD pipelines that deploy to Hetzner VPS hosts using Docker Compose, covering image builds, remote deploys, and environment promotion. • Built blue-green deployment workflows using Bash and Docker Compose, so services running outside Kubernetes could release with no downtime. • Deployed services to a Kubernetes environment running Knative across client projects: writing service manifests, setting env configuration, and handling rollouts. • Built AI and LLM workflow apps using LangChain and RAG (Pinecone, pgvector), and integrated Stripe and PayPal payments. This broad product surface helps with debugging and working across teams. • Worked on a government-funded R&D project: a Java SpringBoot proxy that lets non-JVM projects use decentralized identity (SSI).

SambaPOS — Mobile Application DeveloperSep 2020 – Mar 2021
