Hire the Best CI/CD Freelancers
in Israel

Hey, I'm Serge — a DevOps engineer and Linux sysadmin with 16 years of hands-on experience. Top Rated Plus on Upwork, $70K+ earned, 100% Job Success Score across 24 contracts. My day-to-day involves leading DevOps work for US and Israeli companies — finance, government, tech. Through my employer, the rate is around $100–120/hr — that includes company overhead, account managers, and the usual agency markup. Here on Upwork you hire me directly. No middlemen, no account managers. That's why the rate is lower — not because the work is different. What I focus on most: **Kubernetes and container infrastructure** I've set up and migrated dozens of projects to Kubernetes — EKS, GKE, AKS, and on-prem. I handle the full stack: Helm-based deployments, Grafana + Loki for monitoring and logging, Terraform for infra as code. If your app is still running on Docker Compose and you're hitting limits, this is exactly what I do. **CI/CD pipelines** Setting up proper pipelines from scratch — GitLab CI, GitHub Actions, Helm. Dev/stage/prod environments with proper Git flow so your developers aren't blocking each other. **Cloud infrastructure — AWS, GCP, Azure** Terraform for everything that can be described as code. Multi-environment setups, VPC, networking, RDS, S3, load balancers, security groups. Migrations between accounts, between clouds, and from on-prem to cloud. **AI infrastructure** More recently I've been setting up GPU-based AI infrastructure — Ollama, vLLM, LiteLLM proxy. If you're deploying local LLMs or building AI-powered apps and need the infra side sorted, that's something I can help with too. **A few practical things:** - Up to 8 hours/day — I work focused, not just "clocked in" - You work directly with me throughout the project - I write documentation so your team can actually use what I build If you have a project in mind and want to talk through the scope first, I'm happy to do a short call. Just send a message. Serge ---

I deliver n8n, Make, and Zapier workflows (leads, CRM, email, Telegram/WhatsApp, scheduling) - and I'm a senior developer when the job outgrows buttons-and-zaps. Background: senior developer & automation lead in enterprise high-tech - Java, C#, Python, APIs, SQL, Docker/VPS, CI/CD. I fix what no-code can't: custom logic, deduplication, LLM pipelines, webhooks, and 24/7 reliable deployments. --- What you get in no-code (fast delivery) --- • n8n - webhooks, Gmail, Sheets, Telegram, cron, AI nodes, custom code nodes • Make - lead routing, CRM updates, marketing ops integrations • Zapier - quick MVPs and simple business automations --- Why clients hire me instead of a "Zapier freelancer" --- I'm a senior developer first (Java, C#, Python). In enterprise high-tech I built automation infrastructure from scratch: APIs, databases, CI/CD, Docker/VPS, and production observability - not drag-and-drop tutorials. When Make/Zapier/n8n hit a wall, I don't disappear. I extend the workflow with code: • Custom services, REST APIs, and backend logic • PostgreSQL / deduplication / idempotency (same story never posts twice) • LLM filtering and scoring (Claude/OpenAI) with real error handling • Complex webhooks, auth, retries, and monitoring • VPS + Docker so it runs 24/7 without your laptop Problems simple platforms usually cannot solve cleanly: - Multi-source duplicate detection - Non-trivial business rules and branching - Heavy API orchestration beyond connector limits - AI pipelines with logging and fallbacks - Secure deployment, secrets, and recovery after failures Core stack: n8n · Make · Zapier · Java · C# · Python · TypeScript · PostgreSQL · Telegram · GitHub Actions · Docker · VPS · OpenAI/Claude API Optional scope: Playwright / API / DB test automation if you need a QA framework - say so upfront. Tell me your trigger and outcome. I'll recommend no-code only where it's enough - and code where it isn't.
