About
Bridging delivery management and engineering execution
This portfolio is not positioned as PM-only or developer-only. It is built around the ability to work across client communication, codebases, schedules, deployment pipelines, KPIs, and operational risk in a single execution loop.
A PM who understands the technical layer
Scope and schedules are not handled in isolation. Data flow, batch structure, security, and deployment are all treated as part of execution and decision-making.
A developer who designs for operations
The work does not stop at building screens and APIs. Failure points, auth, observability, release flow, and maintainability are addressed from the start.
A leader who documents decisions
Problem framing, decision paths, KPIs, and handoff readiness are documented so teams can sustain delivery quality over time.

Architecture
OCI1 · Proxmox · OCI2 · OCI3 operating topology
The important part is not only the UI. The current platform separates development from production: OCI1 and Proxmox/dev-center are used for development, GitHub pushes are mirrored into GitLab and built by Jenkins on DevOps-Hub, and OCI2 k3s serves the live domains. OCI3 is now open as the next expansion layer.
Actual operating flow
Cloudflare and OCI1 take the public edge, Proxmox DevOps-Hub handles CI/CD, OCI2 runs the production workloads, and OCI3 is reserved as the next expansion node.
OCI1
Edge routing plus development runtime for direct build-and-test work
- Traefik edge behind Cloudflare
- dev-* domains for active development
- Source-first validation under /Projects
Proxmox / DevOps-Hub
The CI/CD control point after GitHub commits
- GitLab mirror on 100.109.166.6:2222
- Jenkins sync and deploy jobs
- Internal registry on 100.109.166.6:5001
OCI2
