Though I can work in many different domains my favorites are artificial intelligence, web development and algorithm development. I'm keen on working on game development too.

I represent a development team focused on DevOps, cloud infrastructure, backend deployment, and production reliability. We help companies deploy, stabilize, and scale production systems: SaaS platforms, fintech backends, healthcare systems, data pipelines, API-heavy products, and applications that have already outgrown simple deployment setups. Our work usually involves Docker-based deployments, AWS/GCP infrastructure, CI/CD pipelines, staging and production environments, monitoring, logging, database reliability, background jobs, queue-based processing, and production troubleshooting. Typical situations we help with include: – moving from manual deployment to predictable CI/CD – stabilizing production systems with recurring failures – setting up Dockerized backend environments – improving monitoring, logs, alerts, and production visibility – supporting high-load backends and background processing – deploying APIs, SaaS platforms, and data processing services – helping teams understand why systems fail under real usage We are not just focused on “making it deploy”. The goal is to make the system easier to operate, monitor, and scale after launch. Tech stack: Cloud & infrastructure: AWS, GCP, Cloud Run, EC2, S3, RDS, Vercel, Linux, Nginx Containers & orchestration: Docker, Docker Compose, Kubernetes CI/CD: GitHub Actions, GitLab CI/CD, Jenkins, AWS CodePipeline Monitoring & observability: Prometheus, Grafana, Sentry, Datadog, structured logging, alerts Databases: PostgreSQL, MySQL, MongoDB, Redis, ClickHouse Queues & background jobs: Kafka, NATS, Redis queues, scheduled jobs, cron workflows Backend stack: Node.js, Python, Go, Java, REST APIs, WebSockets Security & access: environment management, secrets, role-based access, Keycloak, deployment hardening

🔥 Send me your idea — and I’ll give you a free initial consultation with practical thoughts, possible solutions, and a rough time and cost estimate. Legacy systems draining budget, slowing delivery, and blocking growth? At OSKI Solutions, we help companies modernize legacy applications and build scalable cloud-ready products with our 3x delivery strategy: experienced engineers + AI-assisted coding + disciplined execution. That means you get more than just developers. You get a team that can move significantly faster on implementation, reduce repetitive work through AI-assisted workflows, and still keep architecture, maintainability, and business priorities under control. Most of our engineers are from Ukraine, and we’ve built a delivery model that combines strong technical talent with modern AI tools to help clients ship faster without sacrificing code quality. Over the past 20+ years, I’ve worked as a senior engineer, architect, and ex-CTO, helping startups, SMBs, and enterprise clients rebuild outdated systems into secure, scalable, future-ready platforms. We work hands-on with .NET, Node.js, React, and modern cloud infrastructure to turn brittle systems into products that are easier to maintain, extend, and grow. What we do best Backend Development .NET Core, ASP.NET MVC, C#, Entity Framework Node.js, Express, REST APIs, GraphQL APIs Microservices, event-driven systems, business-critical backend logic Frontend Development React, Next.js, TypeScript, Redux Angular, Vue.js, SPA and PWA development Responsive interfaces, Tailwind, Material UI Legacy Modernization Legacy .NET and custom business platform modernization Monolith to modular/cloud migration Performance, maintainability, and technical debt reduction CMS & Business Platforms Umbraco CMS, Umbraco Cloud, migrations, custom development ERP-related systems and workflow platforms Internal tools, client portals, dashboards, admin systems Cloud & DevOps Azure, AWS, Google Cloud Docker, Kubernetes, CI/CD pipelines GitHub Actions, GitLab CI, deployment automation Databases SQL Server, PostgreSQL, MySQL MongoDB, Redis, caching and query optimization API Integrations & SaaS Stripe, PayPal, Twilio, SendGrid Slack, Shopify, Zoom, QuickBooks, Google Maps SaaS integrations, workflow automation, external service connectivity Why clients choose OSKI Solutions 3x delivery strategy: senior engineers + AI-assisted coding + structured execution 20+ years of experience modernizing complex systems CTO-level thinking focused on business outcomes, not just tickets Full-cycle delivery from architecture to deployment Lean, practical approach that keeps MVPs and modernization efforts within scope Clear communication with weekly demos, tracked hours, and transparent reporting Selected results One Motion Technologies — designed and built ERP system from scratch TutorPro — helped scale a SaaS platform, supporting 3x adoption growth in 2 years Umbraco platforms — delivered 15+ CMS and business platforms, including cloud migrations and integrations What our 3x approach means in practice We use AI to accelerate coding, prototyping, refactoring, and repetitive engineering tasks — but not to replace engineering judgment. The result is: faster delivery, cleaner implementation, better budget efficiency, and a stronger technical foundation for future scaling. 💬 Send me a message, and I’ll review your project, suggest the best approach, and give you a realistic next-step plan.
