Custom SERP crawlers and SEO data warehouses are among the technical services offered by UDP Consulting, a firm specializing in engineering-grade infrastructure for technical teams and businesses seeking infrastructure ownership without vendor lock-in. The company builds SEO data systems using Scrapy, PostgreSQL, and MariaDB, delivering bespoke backends for search data aggregation and analysis. Beyond SEO infrastructure, UDP Consulting provides VoIP development using OpenSIPS, Flexisip, and RTPEngine for telecom operators and ISPs, along with 3CX consulting, custom backend development with FastAPI and Docker, Nginx deployment on Hetzner infrastructure, and cybersecurity hardening. Local AI integration is also offered. Pricing is clearly structured: 3CX consulting starts at €800, and VoIP infrastructure projects start at €4,000. The company’s engagement model emphasizes direct engineer access with no hand-offs, architecture documentation provided before any coding begins, and runbooks included at project handoff. Technical depth covers SIP traces and pcap analysis rather than relying on vendor support portals. All deliverables are scoped and fully priced before work starts. The firm targets technical teams that require production-grade solutions and want to avoid proprietary platform dependencies. UDP Consulting positions itself as a no-compromise provider, contrasting its approach with agencies that layer account managers between the client and the engineer. The combination of SEO data infrastructure, telecom, and custom backend services makes it a specialized option for organizations with engineering-driven requirements.
