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

Java & Spring Boot Architect | AI-Powered Backend Systems | 14+ Years Experience I am a Java & Spring Boot architect with 14+ years of hands-on experience building production-grade enterprise systems — from core banking platforms to AI-integrated microservices. I hold a BSc in Computer Science & Technology and now work as a dedicated full-time freelancer on Upwork, bringing the same rigour I applied in large fintech institutions directly to client projects. My core expertise spans Spring Boot, Spring Framework, and microservices architecture, with deep practical knowledge of SSO & Keycloak, Docker, DevOps pipelines, and GitLab CI/CD. I design systems that are secure, observable, and built to scale — whether that means integrating Kafka for event-driven flows, Flowable BPMN for workflow automation, or AWS for cloud infrastructure. Over the past year I have been heavily invested in the AI/LLM frontier: building Spring AI applications, wiring up MCP (Model Context Protocol) servers, running local models via Ollama, and implementing advanced patterns like tool calling, RAG pipelines, and AI agent workflows. I see AI not as a separate layer but as a first-class citizen inside enterprise Java backends. If you need someone who understands both the old-school reliability of enterprise Java and the new possibilities of AI-augmented architecture — let's talk.
