Hi, I build software that performs reliably under pressure — fast, stable, and easy to maintain. I have over a decade of experience working with .NET/C#, contributing to projects of all sizes, from small business tools to large-scale platforms handling thousands of requests per second. Backend & APIs Design and build scalable APIs with .NET Core. Develop microservices that handle failures gracefully. Improve performance and reduce bottlenecks in existing systems. Databases & Performance SQL Server & PostgreSQL optimization. Efficient schema design and query tuning. Time-series solutions using TimescaleDB. Caching strategies with Redis. Event-Driven Systems Kafka-based architectures. Reliable message processing and system decoupling. Cloud & Deployment Microsoft Azure deployments. Docker containerization. Production stability and monitoring. Datadog logs and metrics. Frontend Blazor, JavaScript, HTML/CSS. Modernizing and maintaining WinForms apps. Integration with third-party services (Google Maps, Mapbox, OpenStreetMap). How I work Clean, maintainable code. Clear communication and consistent progress updates. Comfortable working in Git, Jira, Slack, and ClickUp. Focus on long-term stability.

Platform & DevOps engineer with 10+ years building infrastructure that ships faster, costs less, and stays up. I help startups and scale-ups across fintech, e-commerce, and SaaS design and operate cloud-native platforms on AWS and GCP. My work spans the full stack of modern infrastructure: Kubernetes cluster design and hardening, GitOps pipelines with GitHub Actions and ArgoCD, Terraform modules for repeatable multi-environment deployments, and observability stacks using Prometheus, Grafana, Datadog, and ELK. Beyond standard DevOps, I bring AI-Ops capabilities that give teams a real edge. I deploy and manage self-hosted large language models using Ollama and Open-WebUI, keeping sensitive data on-premises and fully GDPR-compliant. I build intelligent automation workflows with n8n that replace manual handoffs with event-driven pipelines — from infrastructure events to automated actions without human intervention. Security is built in, not bolted on. I implement DevSecOps controls including WAF, AWS GuardDuty, IAM least-privilege, secrets management, and compliance automation. This matters especially for European clients operating under GDPR. Currently at Thoughtworks as an Infrastructure Consultant, I partner with engineering teams to define platform strategy, reduce cloud costs, and accelerate delivery cycles. 100% Job Success across 19 contracts. Top Rated on Upwork. If you need someone to architect your cloud platform, migrate workloads, build production-grade CI/CD, or introduce AI-powered automation into your workflows — let's connect.

Hola, My name is Art. I'm a software engineer with strong knowledge of algorithms and data structures. I'm proficient in next languages and technologies: - .NET Stack: C#, WPF, WCF, ASP WebAPI, ASP MVC. - Scala: Play Framework, Akka, SBT, Spark, Hadoop; I'd like to provide good documentation and high-quality software through a lot of automation - unit tests, integration test (with Docker for mocking external services/db).

I have over 9 years of experience in Data Engineering (especially using Spark and pySpark to gain value from massive amounts of data). I worked with analysts and data scientists by conducting workshops on working in Hadoop/Spark and resolving their issues with big data ecosystem. I also have experience on Hadoop maintenance and building ETL, especially between Hadoop and Kafka. You can find my profile on stackoverflow (link in Portfolio section) - I help mostly in spark and pyspark tagged questions.
