# Del Rey Valmoria > Self-taught automation engineer based in the Philippines, working remotely. Builds workflow automations for small businesses (home-service companies, clinics and practices, online stores, and agencies as a white-label partner): missed-call text-back, instant lead replies, appointment reminders, review requests, stock and catalog checks. Fixed prices: $150 audit, builds from $1,500, $500/month care. Also builds data pipelines, internal tools and API systems. Contact: hello@delreyvalmoria.com · Site: https://delreyvalmoria.com/ · Contact page: https://delreyvalmoria.com/contact/ ## How to read this site Every figure published on this site is a measurement taken from a system that ran. Where a number was not measured it is omitted rather than estimated, and degraded states are reported rather than hidden. The 18 case studies are 18 documents, several covering different components or stages of the same system — they are not a count of independent clients. ## Who this practice serves - [Automation that answers leads for home-service businesses](https://delreyvalmoria.com/for/home-services/): Missed-call text-back, 60-second web-lead replies and review requests for cleaning, HVAC, plumbing, roofing and lawn businesses. $150 audit first. - [Fewer no-shows and missed calls for your practice](https://delreyvalmoria.com/for/clinics/): Appointment reminders, missed-call follow-up, review requests and patient recall for independent dental, physio, chiro and med-spa practices. - [Automation for Shopify & WooCommerce stores](https://delreyvalmoria.com/for/ecommerce/): Stock alerts, catalog fix lists and order exception routing built across the apps your store already uses. You own it, with no per-order app fees. - [White-label automation engineering for agencies](https://delreyvalmoria.com/for/agencies/): You sold the automation; someone has to build it. White-label n8n, GoHighLevel and HubSpot builds under your name: NDA, fixed price, full handover. ## Pricing Published, fixed prices (https://delreyvalmoria.com/pricing/): - Automation Audit, $150 (one-time): Find where your business leaks leads and hours. A 45-minute call where you walk me through how the work happens today; A written map of the manual steps, missed handoffs and tools involved; A prioritised fix list with a fixed price for each fix; The $150 is credited in full if you go ahead with a build. - Automation Build, from $1,500 (from, fixed price): The fixes, built and running — usually in about two weeks. Fixed scope and fixed price, agreed in writing before work starts; Typically one to three connected automations around the tools you already use; Tested on your real cases before it goes live; A handover: how it works, what to do when something looks wrong, and full ownership. - Care Plan, $500/mo (per month): Someone watching it, fixing it and adding to it. Monitoring, with alerts when an automation fails; Fixes and small changes, without a new quote each time; One new automation every month; Cancel anytime — you keep everything that was built. ## Services - [AI workflow automation](https://delreyvalmoria.com/services/workflow-automation/): Turn repeated handoffs into a workflow your team can follow. I build automation around the actual operation: where information arrives, who checks it, what happens next, and how a failed step is recovered. AI is useful for interpreting evidence or language; explicit rules keep the process accountable. - [Data pipelines & catalog quality](https://delreyvalmoria.com/services/data-pipelines/): Make the data dependable before building on top of it. I trace how records are created, matched, updated and reconciled. The work can include product normalization, fiscal enrichment, duplicate repair and rebuilding a sync so the same error does not return on its next run. - [Internal tools & operations software](https://delreyvalmoria.com/services/internal-tools/): Software that fits the people doing the work. I build interfaces for the decisions your team makes every day. That means understanding roles, access boundaries, the devices people use and what must be recorded when something changes. - [API integration & system architecture](https://delreyvalmoria.com/services/api-systems/): Connect the systems. Make the failure paths explicit. I work on the boundaries between products: identity, requests, data ownership and recovery. A working integration must account for slow services, expired access, duplicate events and partial failures. - [Interactive websites & 3D web experiences](https://delreyvalmoria.com/services/interactive-websites/): Give people something worth exploring—and a clear way forward. I build interactive websites where the interface expresses the work. This portfolio combines a readable homepage and project atlas with an optional 3D flight console. The experience is a working example of the frontend, interaction and integration decisions I can bring to a project. ## Buying guides - [When should a workflow use rules, AI or human review?](https://delreyvalmoria.com/guides/rules-or-ai/): A practical decision guide grounded in Del Rey Valmoria’s deterministic catalog and AI audit projects. - [How to scope a repair when two systems disagree](https://delreyvalmoria.com/guides/repairing-a-data-sync/): A data-sync repair checklist covering source ownership, pagination, duplicate records, idempotency and reconciliation, with published project evidence. - [What to define before commissioning an internal tool](https://delreyvalmoria.com/guides/scoping-an-internal-tool/): A practical scoping guide for inventory, intake and operational software, drawn from Del Rey Valmoria’s published implementations. ## Case studies ### AI orchestration - [AG Bridge — AI Gateway](https://delreyvalmoria.com/case-studies/ag-bridge/): A JWT-authenticated FastAPI AI gateway with circuit breaker, AES-256-GCM session encryption and Prometheus observability for a multi-product platform.
