Job Description

About the Role We're looking for a senior-level engineer who can own the full stack — from database architecture to AI-driven workflow automation to production infrastructure — with no handholding required.

NET/VB.

NET/C#, and modern JavaScript Administer VPS/Linux production environments: Docker container orchestration, DNS, SSL provisioning, and infrastructure monitoring Build and scale WordPress/WooCommerce e-commerce platforms with custom Elementor theming, optimized checkout flows, and CRO-focused UX Manage multichannel marketplace operations (Amazon, Lazada, Shopee, Carousell) — listings, inventory sync, pricing strategy Execute technical SEO strategy: schema markup, Core Web Vitals optimization, technical audits Implement human-in-the-loop approval pipelines for AI-driven business processes handling sensitive operational data Required Qualifications Minimum 4 years professional full-stack development experience Demonstrated production experience building multi-agent AI workflows (n8n or equivalent) — not just prompting LLMs, but designing branching automation logic with API orchestration Strong hands-on expertise in enterprise SQL database design and performance tuning (not just CRUD queries — schema design, indexing, stored procedures) Proven Docker/VPS/Linux administration experience in live production envi
