Agu Jonas
Systems Engineer · Distributed systems & infrastructure
Senior Software Engineer with a track record of building resilient, distributed systems: from webhook proxy services and encrypted request pipelines to embedding-based semantic search across millions of job listings. I work comfortably across the stack, but I especially enjoy solving hard backend and infrastructure problems: service orchestration, secure data flows, and systems that need to scale without breaking. Currently building Quiqorder.
- Designed a webhook proxy service that fans inbound requests out to downstream services with encryption in and decryption out.
- Built an embedding-based semantic matching system classifying listings against O*NET occupation codes in real time via vector search.
- Manage Kubernetes orchestration across staging and production; backend on EC2 behind Caddy for auto-SSL.
- Building the storefront, order management, and payment flows that let sellers sell on WhatsApp around the clock.
- Automating chat and Status posts so merchants can capture and fulfil orders without being online.
- Generated ZUGFeRD and XRechnung invoices and eased tax remittance via direct FinAPI, Stripe, and Etsy integrations.
- Built automated reconciliation keeping bank transactions current.
- Managed deployments across ECS (production backend) and EC2 (staging + frontends).
- Delivered interactive causal-inference and causal-discovery workflows over datasets with millions of rows.
- Built nodal network visualizations mapping relationships across formulation phase spaces to surface scale-up risks earlier.
- Collaborated with a global team to ship new pages and fix UI bugs.
- Improved design consistency across the site.
- Built file upload, sharing, and permission-management workflows with real-time sync.
- Implemented scalable content indexing and search logic for fast retrieval of user-generated data.
