👋 Hey, I’m Serhii
I’m an AWS Platform Engineer who makes sure your cloud infrastructure actually runs — reliably, securely, and without 3 AM alerts.
I work freelance with teams ranging from 3-person startups to Series B companies. Based in Ukraine 🇺🇦, UTC+3, async-friendly, so you’ll always know where things stand.
🛠️ What I can do for you
- 👻 AWS environment that grew organically and is now haunted
- Audit, restructure, and manage your AWS infrastructure — VPC, IAM, ECS, EKS, RDS, networking, and whatever else got bolted on
- 🏗️ A migration that someone started and nobody wants to finish
- Plan and execute on-prem to AWS migrations — phased, zero drama, product keeps shipping throughout
- 🐢 CI/CD pipelines that take 40 minutes and nobody knows why
- Build CI/CD pipelines that deploy to AWS fast, securely, and without anxiety
- 😬 ECS / EKS / EC2 workloads that feel fragile
- Set up and harden containerised workloads on AWS — Fargate, EKS with Karpenter, autoscaling, safe deployments
- 📋 “We need to be compliant and have no idea where to start”
- AWS security & compliance — GuardDuty, Security Hub, CloudTrail, IAM least-privilege — so “we’ll fix it later” doesn’t end up on the news
- 💸 AWS bill that keeps climbing
- Cost optimisation — Reserved Instances, Savings Plans, right-sizing, scale-to-zero — find what’s quietly burning money and fix it
- 🔓 “We got a pentest report back and it’s… not great”
- AWS-specific remediation: WAF rules, IAM hardening, Security Hub findings, network segmentation
- 🧠 Infrastructure held together by the memory of people who no longer work there
- Terraform IaC for AWS — codify your environment so it outlives any single engineer
I’ve also worked with GCP, DigitalOcean, and Hetzner — but AWS is where I specialise.
