Hire the Best Software Development 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 ---

$400M+ in transactions processed across platforms we built. 100,000+ tickets sold on a product shipped from zero. 20+ countries reached by an EdTech app delivered end-to-end. I'm not listing what's possible — I'm listing what's already running in production. I'm a full stack developer and software architect based in Israel, and the CEO of a 40+ engineer development agency. When you work with me, you get a senior technical partner who understands the code and the product — and a full team behind delivery when scope requires it. 🔹 Full Stack & SaaS Development Scalable multi-tenant architectures, B2B dashboards, internal tools, and AI-integrated SaaS. Core stack: React, Next.js, Vue.js, TypeScript, JavaScript, Python, Node.js, Laravel — full stack web developer depth from database schema to UI. 🔹 Fintech & Banking This is where I'm different from most full stack developers on this platform. We've built card issuing systems, treasury management platforms, AML/KYC pipelines, cross-border payment rails, and crypto-to-fiat flows. Live integrations: BlackRock, DocuSign, Salesforce, Rail API, Kraken, SEPA Instant. Production experience, not theoretical. 🔹 Mobile App Development Native iOS (Swift) and Android (Kotlin) for security-critical applications. React Native for cross-platform.

I build AI as a functional product layer, not a feature checkbox. When you hire me as your full stack developer, you're not getting a solo freelancer bottleneck. You're getting a senior technical lead with backend, frontend, mobile, and DevOps teams — all behind one point of contact, one contract. Tech: Python · Django · FastAPI · React · Next.js · Vue.js · TypeScript · JavaScript · Node.js · Swift · Kotlin · React Native · PostgreSQL · MySQL · Redis · ClickHouse · AWS · GCP · Docker · Kubernetes · Solidity · Web3.js Send me a direct message to get 30-minute session to map your architecture, align on tech stack, or define your MVP roadmap before development begins.
