Hire the Best AWS CodeDeploy Developers
in Ukraine

Enterprise teams hire me when the backend needs to be built right from the start - NestJS, TypeScript throughout, AI pipeline integration, and full-stack delivery from day one. What I have built: - Delivery Management Platform (0.5 yrs, team of 3): Full-stack logistics system handling real-time driver routing via Mapbox, order distribution, overload redistribution, and delivery plan confirmation flows. Stack: NestJS, Next.js, React, PostgreSQL, Supabase, AWS Lambda, TypeORM, Docker. - Digital Factory Software Suite (2 yrs, team of 3-5): Modular AI-powered platform for monitoring industrial system states and generating recommendations via configurable AI agents. Built document parsing pipelines for AI-driven content processing across multiple file formats. Stack: NestJS, Node.js, Angular, Weaviate, LangChain, LangFuse, Unstructured, TypeORM. - Model Training Service (1.5 yrs, team of 6-8): AI-based optical quality control and defect detection system installed on manufacturing assembly lines. End-to-end feature delivery, backend optimization, API integrations. Stack: NestJS, Angular, React, Next.js, TypeScript, MySQL, Redis, Azure, Docker. - Vendor and Homeowner Marketplace (1.5 yrs, team of 2-3): Full platform connecting service providers with homeowners — system architecture design, backend services, internal and third-party API integrations. Stack: NestJS, Angular, React, Next.js, PostgreSQL, Prisma, Redis, AWS, Auth0, Docker. How I work: Architecture documentation before code. Every feature has unit tests before it ships. I write consistent TypeScript throughout the codebase and enforce coding standards through code reviews, not just in my own work. I own deployment and environment configuration end-to-end — I don't hand off to someone else to ship. I operate with the full backing of Meduzzen's senior engineering team. Every commit I ship is reviewed by our internal technical leads before it reaches your codebase. If I am unavailable, your sprints do not stop. Core stack: NestJS, Node.js, TypeScript, Express, Angular, React, Next.js, PostgreSQL, MySQL, MongoDB, Redis, Weaviate, AWS, Azure, Docker, Nginx, LangChain, LangFuse, TypeORM, Prisma, Auth0, GitHub Actions, GitLab CI/CD. If you need a NestJS or Node.js engineer who owns backend architecture, integrates AI pipelines, and ships clean TypeScript without hand-holding — send me a brief. I reply within 4 hours.

I am a Python backend developer with 6 years of development experience, focused on asynchronous Telegram bots, API integrations, business automation, and internal tools. I build backend systems and Telegram bots in Python for admin workflows, paid communities, data processing, and reliable automation. My work usually includes: - Telegram bots from scratch - Admin panels and moderation workflows - API integrations and webhooks - Data parsing and automated notifications - Full database setup and management - VPS server configuration and deployment I mainly work with Python, aiogram, Pyrogram, aiohttp, PostgreSQL, Docker, Nginx, Linux, REST APIs, and webhooks. I focus on clean backend logic, reliable state handling, and simple maintainable solutions without adding extra technologies just to make the project look more complex.

I work with engineering leaders and CTOs who are scaling fast but fighting the same battles: deployments that take hours, environments that drift, DevOps bottlenecks that block every release, and infrastructure that isn't ready for AI workloads. I eliminate those bottlenecks - permanently. With 90+ completed projects, $900K+ earned on Upwork, and a 100% Job Success Score, I've led infrastructure transformations across Fintech, Healthcare, E-commerce, and SaaS - delivering measurable outcomes that show up on the P&L, not just in a CI/CD dashboard. Typical Problems I Solve → Deployments take hours instead of minutes → Infrastructure costs keep growing without visibility → DevOps bottlenecks block engineering teams → Kubernetes environments become difficult to maintain → AI initiatives are delayed because infrastructure isn't ready → Need a DevOps engineer for cloud migration or infrastructure audit Proven Client Results ▪️ HRM Platform → Challenge: Deployments took 3 hours, causing constant developer delays and release anxiety. → Solution: Docker parity environments + fully automated CI/CD pipeline across all environments. → Business Impact: Deployment time cut from 3 hours to 2 minutes - 98% improvement in release speed. ▪️ Connectivity Platform → Challenge: Provisioning a new environment took 1.5 weeks, blocking team velocity. → Solution: Infrastructure automation with Terraform + CI/CD pipeline standardization. → Business Impact: Provisioning time cut to 1 hour. 200-300 monthly automated deployments. Team efficiency +30-35%. ▪️ Zmyle (German E-commerce, 17+ multi-tenant sites) → Challenge: Legacy infrastructure couldn't handle Christmas peak traffic across 17 sites. → Solution: Full migration to Kubernetes with CI/CD, monitoring stack (Prometheus/Grafana/ELK), and VPN. → Business Impact: Zero downtime during peak season. Scalable multi-tenant architecture now handles 10x traffic spikes. What Working With Me Looks Like → DORA metrics-driven delivery - Deployment Frequency, Lead Time, MTTR, Change Failure Rate measured and improved → Zero-Drift Infrastructure - no more 'works on my machine' incidents → FinOps awareness built into every pipeline - cost visibility is not an afterthought → AI-ready infrastructure - prepared for LLM workloads, GPU orchestration, and vector databases → Full observability stack: Prometheus, Grafana, ELK, Datadog - you see everything I lead a team of Senior DevOps Engineers and Cloud Architects. Whether you need a one-time infrastructure audit or a long-term engineering partner - I structure engagements around your business outcomes, not billable hours. Industries: Fintech · Healthcare · E-commerce · SaaS · Blockchain Stack: AWS · GCP · Azure · Kubernetes · Terraform · GitOps · ArgoCD · Prometheus · Grafana · GitHub Actions · GitLab CI · Docker · Ansible · AI workloads Available during US business hours (EST/PST overlap).
