Since 2025: from LLM-assisted debugging of production issues to an agentic AI platform, designed and shipped in 2026 and live in production. It has two halves: Sporfie Agents, where the team investigates and operates, and CodeDev, where coding agents build.

Sporfie Agents (Python / FastAPI, AWS Bedrock, MCP): a multi-agent system for investigation and operations. An LLM router sends each question to one of five specialist agents (infrastructure, operations, design, development, tech lead), each a persona with a fail-closed tool allowlist and its own case memory. 19 read-only MCP servers over Kubernetes, CloudWatch, Prometheus, GitHub, SQL, Jira and more; any change goes through a signed plan, a human approval in an AI-free app and a separate executor, with a full audit trail. Reachable from the web, Slack, Claude Desktop (MCP) and GitHub, where a Tech Lead agent reviews every PR. One LiteLLM gateway gives each agent a key, a budget and a cost per conversation; a regression eval suite gates releases.

CodeDev (TypeScript / Node, React, Kubernetes): a cloud workstation where Claude Code (Agent SDK), Codex and OpenCode build and run the real stack and hand back a branch, a PR and a verified preview URL. Per-branch preview environments, an epic mode that runs parallel agents in git worktrees against a server-checked definition of done, deterministic commit and push guards as hooks, and an MCP so other agents can delegate coding work.

Platform and back end (2016 onward): building and running the platform end-to-end since day one of this live-streaming SaaS. Led the move to Kubernetes in 2020 with a strong GitOps + IaC culture; introduced Karpenter for smarter autoscaling, built a Kubernetes-native serverless framework to bypass Lambda limits, and run GPU workloads for streaming and AI tooling.

Own multiple back-end services (Java/Go/Python/Node), lead performance and scalability work, create load-testing suites, and implement multi-layer caching (including CloudFront for less-dynamic public APIs). Hands-on with CDN architecture and operations: cache strategy, invalidation, edge behavior, origin design, and the observability needed to troubleshoot real-world delivery issues.

Stack: Kubernetes, ArgoCD, Karpenter, Prometheus, Grafana, Docker, PostgreSQL, Java / Spring Boot, Node.js, Python (OpenCV, FFmpeg), Go, Firebase, GraphQL, REST, Redis / Redisson, HAProxy, CircleCI. AWS: Lambda, CloudFront, S3, ElasticTranscoder, CloudWatch. AI: AWS Bedrock, MCP, Claude Agent SDK, LiteLLM, Python / FastAPI.

Freelance consultant on a private cloud solution with OpenShift (Kubernetes), Docker and Kafka. Helped drive GitOps practices during the Kubernetes migration.

• CI/CD refactor using a GitOps approach

• Namespace quota management
• Docker image security scan set up with Anchore Engine

Lean startup experiments with cloud deployment and high-productivity tools (Java 8, Spring Boot, AWS, Firebase, GraphQL, REST, Elasticsearch, Docker, CircleCI, serverless and microservices architectures, Spring Data, MySQL).

Back-end Java development of GlassIG, a SaaS for corporate information governance. Involved in the migration from on-premise infrastructure to the cloud.

• Coaching the dev team (talks on unit/integration tests and Java common libraries)
• DSL for integration test automation
• Application security and code quality (Veracode, SonarQube)
