ERP

ERP / CAD Product Configurator

Compatibility descriptor engine ensuring wall, door, and panel combinations are valid before reaching a construction site — backed by live Odoo article data and IMOS CAD rules.

Hard part

Building an intelligent engine that doesn't just reject invalid combinations — it suggests the most compact valid one automatically, using live Odoo article data and IMOS CAD rules evaluated server-side before any order can ship.

Enterprise UI

Enterprise Web File Explorer

Microsoft-style file management interface with folders, uploads, metadata, previews, permissions, and scalable UI state.

Hard part

DevOps

CTL AI Watchdog Agent

Kubernetes-style cluster control agent with AI-driven service restart, log inspection, volume management, and real-time topology visualization.

Hard part

Designing a reliable AI agent loop that can safely act on live infrastructure — deciding when to restart a service, when to escalate, and when to wait — without creating cascading failures or acting on stale state.

Automation

LinkedIn Job Agent

Supervised Playwright automation agent that scores LinkedIn jobs, generates tailored resumes via a remote API, and submits Easy Apply applications — with quota enforcement, audit trails, and human-like behavior.

Hard part

Building a reliable form-filling engine for an undocumented, frequently-changing DOM — mapping arbitrary question text to structured answers (region-aware work auth, salary in any currency and unit, years-of-experience per technology) without a schema to rely on.
