Technical Lead and SRE Architect mentoring a team focused on infrastructure provisioning and developer experience.

• Designed and built a self-service AI Agent Platform with MCP tool-calling, multi-agent orchestration, and HITL approval flows for internal infrastructure-support workflows — ~200K req/day, ~800 registered tools, ~60 agents in production. Engineering teams contribute their own tools and agents.
• Slashed EKS cluster costs by 40% via Karpenter consolidation, migration to ARM and Spot nodes, VPA, and custom scheduling.
• Consolidated 12 legacy API gateways onto a single Kong gateway at ~10k RPS with 99.99% uptime during cutover; built a GitOps-driven control plane for API route management.
• Designed and deployed a fully automated cloud-resource provisioning platform with GitOps (Terraform + Terragrunt) — provisioning time for new services from days to minutes.

Led migration of 300+ microservices from legacy AWS infrastructure to AWS EKS.

• Engineered automated provisioning of multiple EKS clusters with Terraform + Terragrunt — repeatable, auditable infrastructure foundation.
• Built the observability stack with Prometheus, Thanos, and Grafana — high-cardinality metric storage, SLO dashboards, and cost tracking across the EKS fleet.
• Improved deployment velocity and safety via service mesh (Linkerd) with automated canary rollouts via Flagger.
• On-call 24×7 on a bi-weekly rotation.

Designed and implemented the infrastructure of a Cloud IIoT Platform while leading a team of 6 polyglot engineers in a KanBan model — workload distribution, technology selection, mentoring, customer integration.

• Built a bespoke Kubernetes Ingress Operator for bare-metal Kubernetes clusters using RedHat operator-sdk (custom control-plane work, not just operator consumption).
• Secured and streamlined the software delivery lifecycle by integrating ArgoCD with Keycloak — a secure, auditable GitOps workflow for Helm-based deployments.
• Implemented Google SRE golden signals (latency / traffic / errors / saturation) on bare-metal Kubernetes using Prometheus.

Containerized all services of a distributed Industrial IoT platform with Docker; orchestrated via Kubernetes and D2iQ. Polyglot delivery across Python, Go, Java, and C#.

• Built a serverless framework in Python running code on containers via Kubernetes / Marathon / Metronome.
• Built a parallel metric aggregation publisher for StatsD in Golang.
• Built an OPC → MQTT data pipeline service in C# using Avro RPC and REST.
• Built an OpenID Connect Identity Provider microservice using Spring OAuth2 with JDBC, Active Directory, LDAP, and Mongo storage backends.
• Implemented dynamic proxying and JWT bearer authentication using OpenResty LuaJIT.

Core developer for NCache Enterprise (Redis-class distributed cache native to .NET) and NosDB Enterprise (CouchDB/MongoDB-class NoSQL JSON store native to .NET), both in C#.

• Reimplemented Microsoft's Collections to prevent Large Object Heap (LOH) leakage.
• Implemented the ASP.NET Core Session State Management middleware with NCache backend storage and full session-locking support.
• Built file-storage-based B+ Tree indexing with support for single-attribute and compound indexes.
• Built the query execution system using Streams and nested Enumerables.
