Projects
Projects across AI platforms, developer platforms, and automation systems.
Global Shipping AI Workflow Automation PoC
Owned the infrastructure, observability, and performance-verification tracks of a four-week n8n workflow-automation PoC for a global shipping company. I bootstrapped a five-VM greenfield architecture running n8n Community Edition in Queue Mode, and built a Grafana Alloy remote_write observability stack. I ran the hybrid-OCR prompt PoC for MSDS document-verification automation and single-handedly performed k6-based performance and load testing. I also wired up the MS Teams AI chatbot and its human-in-the-loop approval gate. Separately from the PoC environment, I reproduced the same stack with Terraform on an internal AWS account so the team could build and verify workflows outside the closed network.
AI Agent Observability — Internal Platform Telemetry Layer
Built the AI agent observability layer of an internal DevOps platform. OpenTelemetry signals from Claude Code and an open-source agent runtime (Hermes) flow into VictoriaLogs/VictoriaMetrics and surface in Grafana, attributing agent usage, cost, and success rate per user and per agent across the engineering organization.
Asset Management n8n Workflow Automation PoC
Built the deployment package and PDF-to-PPT automation workflows for an n8n PoC with an asset-management client at InfoGrab. The stack ran on Rocky Linux with rootless containers, n8n, a reverse proxy, and a PDF parsing service. I designed the asynchronous upload/status/download flow that turns a large PDF into two PPT outputs: reference-source and structured-review.
DGX Spark MLOps Stack — Dual-Node LLM Pipeline
Built an end-to-end LLM cycle for internal use on two NVIDIA DGX Spark nodes (Production + R&D) — ClearML 10-step pipeline, NGC training containers, AWQ quantization, vLLM inference, an OpenAI-compatible router, and an operations agent that drives the stack from chat.
Insight Marketing & Docs Portal Infrastructure — Unified Pulumi IaC with GitLab CI/CD
Owned the infrastructure and CI/CD track for the company marketing site (Insight v2) and the external-product docs portal. A single Pulumi (TypeScript) stack defines the AWS footprint for both builds, GitLab CI standardizes S3 deploys and CloudFront invalidation, and every merge request gets its own review hostname routed by an edge function. The v1 to v2 cutover swapped only the CloudFront origin, leaving domain, certificate, and DNS untouched.
Office Infrastructure Buildout — Dual-WAN Redundancy and Network Segmentation
Greenfield on-prem network designed and built for an office relocation. A MikroTik RB5009 edge router runs dual WAN (PCC + failover) across two ISPs, three VLANs separate office, server, and management traffic, and two WireGuard instances split employee access from external-partner access. Diagnosed and fixed the session drops and the missing firewall condition that surfaced once a second uplink was live.
DevOps Platform Operations & Access Management
Ongoing operational ownership of InfoGrab's internal DevOps platform — Keycloak SSO, IAM lifecycle, Teleport-based infrastructure access, Kubernetes operations, and credential and access governance. A continuous responsibility, not a discrete engagement.
Digital Signage DevOps & AWS IoT OTA Deployment
Built a production-ready digital signage system by codifying AWS infrastructure with Pulumi and building GitHub Actions CI/CD plus an AWS IoT Core-based device OTA update pipeline, automating the full deployment path from server applications to remote software updates on field signage devices (Android).
Financial DevOps Toolset and On-site Migration
Designed a DevOps toolset for 105-125 developers by migrating SVN + ChangeFlow to GitLab. Ran the migration of five systems in parallel, established a Git strategy for the ITSM-controlled environment (no squash/rebase/force push), and authored situation-based operations and incident response guides. Built a containerized platform under Rootless Docker constraints while meeting security audit requirements.
Distributed SCM Consolidation and CI/CD Standardization
Consolidated source control scattered across SVN, a self-hosted GitLab, and local build environments onto a single GitLab platform, and built the company-wide CI/CD system from the ground up. Designed a standard template system per OS (Linux/Windows), build system (Java/C), and deployment method (SSH/Kubernetes/Docker) combinations. Containerized Java projects by JDK version. Defined phased rollout scope for C projects based on server dependency analysis.
Financial Cloud DevOps Platform and Legacy Migration
Migrated SVN + Change Flow file-based deployment to air-gapped GitLab CI/CD. Built DevOps toolset on existing private cloud infrastructure and integrated on-premises GitLab Runner for a platform of 1,994 users and 579 projects. Built image integrity system based on Helm Chart hash and container Digest verification.
VibeCraft: AI-Powered One-shot Dashboard Generator Agent
An Agentic AI tool that transforms SQLite data into executable React dashboards with a single prompt using Gemini CLI and MCP Server. Removes ambiguity through prompt layering to generate consistent quality outputs. Won Special Award in a public-private partnership competition with 1000+ participating teams.
Air-gapped Kubernetes Platform and Developer Experience Innovation
Transformed an environment where VDI resource limitations made builds impossible into Kubernetes-based personal development environments. Provided independent environments for 10 developers via dynamic wildcard domains (*.dev.example.com) with JetBrains Remote Debug support. PoC adoption led to full-scale business expansion.
Bare-metal Kubernetes Homelab (A to Z)
Side project running a bare-metal Kubernetes cluster built from three PCs, with MikroTik BGP+ECMP networking, Cilium Gateway API, and a GPU node.
Enterprise-wide CI/CD Platform for Heterogeneous Environments
Introduced GitLab CI/CD to SVN + manual deployment environment, designing unified pipeline templates covering 14 representative projects across Java/C#, Linux/Windows mixed environments. Built Nexus-based common build environment to eliminate server dependencies. Over 30,000 pipeline runs in the first year, establishing enterprise-wide standard.
NKS-based Containerization and GitOps System Implementation
Migrated SSH-based deployment to NKS + ArgoCD GitOps system. Standardized deployment packaging through application containerization, enabling instant image-based rollbacks. Conducted on-site GitOps training for 10 operations team members.
GitLab Cloud Migration for Data Residency Compliance
Migrated the source control system to NCP self-managed to meet a requirement that data reside domestically. Independently handled the cutover, moving repositories as-is with the GitLab backup utility between version-matched instances.
Gait Pattern Analysis Dataset Collection Infrastructure
Built infrastructure to collect walking data from a stage environment surrounded by 80 CCTVs for a public security agency's gait pattern analysis research. Designed disk-based transfer for tens of terabytes of footage and developed a pipeline linking pose extraction to dataset generation.
Real-time Video Analysis Inference Server Development
Developed an inference server running object detection and pose estimation with trained YOLO models for a public security agency's gait pattern analysis system. Targeted 30 FPS, decoupling ingestion from inference via Kafka and storing results in MongoDB for query. The project stopped at the PoC stage.
Smart Agriculture Water Management Backend System
Developed a backend system for efficient agricultural water management by integrating public data APIs and IoT sensors. Implemented flexible crawling architecture with Strategy pattern for dynamic runtime target configuration.
Industrial Safety Object Detection Model Fine-tuning
Fine-tuned YOLOv5 model to detect safety violations (missing hard hats, fallen workers, fire) in industrial environments. Developed environment-specific optimized models using tens of thousands of labeled images, managing experiments with ClearML for continuous model improvement.
Gait Pattern-Based Person Identification System Infrastructure
Built CCTV network, GPU infrastructure, and data pipeline for an AI system that identifies people through gait patterns.
