👋 Hi, I’m Vasiliy Yasko

GIS developer & specialist working with ESRI, QGIS, GeoServer, Unreal Engine (3D/real-time), and modern web/Python.

Currently: working as a GIS developer with years of Smart City project experience.
My Goals: deepen expertise in Unreal Engine and ESRI to contribute to Digital Twin development for infrastructure and urban innovation worldwide.

About

I work with GEOSOL and ISGEO as a GIS developer and GIS specialist. My expertise spans ESRI products and Unreal Engine for 3D visualization, plus plugins and automation for QGIS, ArcGIS Pro, GeoServer, and PostgreSQL/PostGIS. I also build web apps (JavaScript, React, Angular, Node.js) and Python backends for data processing and integration.

I’ve contributed to government projects and collaborated with large enterprises (banks, infrastructure) where GIS is mission-critical. I’m active in Smart City initiatives—especially administrative systems and road infrastructure—with a strong focus on digital twins and urban automation.

My goal is to deepen expertise in GIS automation, real-time 3D, and smart-city infrastructure—building scalable systems that connect geospatial data, web tech, and digital twins for impactful applications.

Core skills

ESRI stack, QGIS, ArcGIS Pro, GeoServer
PostgreSQL/PostGIS, spatial ETL, data pipelines
Unreal Engine (3D/real-time visualization)
JavaScript/TypeScript (React, Angular), Node.js
Python (automation, APIs, data processing)
Plugins, extensions, and custom frameworks for GIS

Current focus

Digital twins for Smart City / infrastructure
Deploying services with Docker & Kubernetes (k3s) on Linux servers
Real-time geospatial visualization and automation
Reliable web services for GIS integrations

Hands-on: VPS / K3s Lab

I run a personal cluster to practice production skills for Digital Twins.

Stack I operate

K3s (Kubernetes) on Linux (Ubuntu / Fedora / Rocky)
Traefik (ingress, Let’s Encrypt TLS), Docker runtime
Keycloak (SSO/IAM), MinIO (S3), OpenSearch (search)
Prometheus + Grafana (metrics/alerts), Loki (logs)
Argo CD (GitOps), Helm (packaging), Terraform & Ansible (IaC)
Proxmox VE (virtualization) for homelab nodes

Operational strengths

Designing namespaces, RBAC, and network policies
GitOps workflows, progressive delivery, safe rollbacks
TLS, OIDC/SSO, and secrets & identity management
Backups & disaster recovery with S3/object storage
Observability: metrics, logs, dashboards, alerting
Cost awareness & right-sizing for edge/DT workloads

Philosophy & Inspirations

My worldview is shaped by thinkers and activists who stood against war, supported science, promoted open knowledge, and defended fairness in technology.
