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
