API Integration Services for Business Systems
I am a Texas-based API integration developer connecting the systems your business already runs — CRMs, SaaS tools, payment systems, third-party APIs, and the automation layer that ties them together. 25 years in computer science, U.S. Army veteran, single-principal delivery. The work is unglamorous and the work is critical: webhook handlers that do not lose events, retry logic that does not double-charge, audit trails that survive an SOC 2 review.
Who I help
Operations leaders whose teams copy data between systems by hand because no one ever wired up the integration. CTOs whose first integration was built by the founder five years ago and now breaks every other week. Companies that bought a SaaS product expecting it to "just integrate" with their other tools and are still waiting six months later. Founders building software that depends on Stripe, Twilio, SendGrid, HubSpot, Salesforce, QuickBooks, or any of the hundreds of business APIs that look easy at the demo and become real engineering work in production.
Services I offer
- CRM integrations. HubSpot, Salesforce, Pipedrive, Zoho, Close, Copper — bi-directional sync, custom field mapping, webhook handling, deduplication.
- SaaS tool wiring. Connecting the SaaS stack your business already runs — Slack, Notion, Airtable, ClickUp, Asana, Monday, Linear, Intercom, Zendesk, Help Scout.
- Payment system integration. Stripe, PayPal, Authorize.Net, Square, Braintree — subscriptions, one-time charges, invoicing, dunning, refunds, dispute handling.
- Third-party API integration. Twilio, SendGrid, Postmark, Mailgun, AWS SES, OpenAI, Anthropic, Google Workspace, Microsoft Graph — whatever vendor your workflow needs.
- Automation pipelines. The orchestration layer above the integrations — conditional logic, queue-backed retries, scheduled batch jobs, audit trails.
Benefits
- Hours back per week. Every integration is one workflow your team no longer has to do by hand.
- Reliable, not flaky. Production integrations need retry logic, idempotency keys, dead-letter queues, and structured logging. Hobby integrations skip those; my integrations do not.
- Auditable. Every API call logged. Every webhook payload archived. Every state transition tracked. The audit trail survives an SOC 2 review.
- One owner. No agency hand-off. When something breaks at 2am, the engineer on the other end of the email is the engineer who wrote the code.
Related technologies
Laravel 13 + Livewire 4 for the operator dashboards on top of the integrations. Laravel's queue system + Horizon for the orchestration layer. Redis for rate-limit tracking. PHP 8.4 for the backend. PostgreSQL or MariaDB for the audit log. Pest 4 for the test suite that proves the integration works before it ships, including against the vendor sandbox where available.
How an integration engagement runs
Same disciplined shape as my other engagements: scoping call, written specification, two-week sprints, Pest tests alongside features, handover with runbook. The difference for integration work is that sprint zero is the vendor-API reality check: I read the actual API documentation, build a smoke test against the vendor sandbox, and confirm the integration is possible before we plan the build. Vendors sometimes document features they do not actually ship; finding that out in sprint zero is cheaper than finding it out in sprint four.
Can you integrate our CRM with our other tools?
Yes. HubSpot, Salesforce, Pipedrive, Zoho, Close, and Copper are the most common ones I have worked with. Bi-directional sync, custom field mapping, webhook-driven updates, deduplication on contact merge — the integration is built to a specification, not "as close as we can get".
Do you build payment integrations?
Yes. Stripe is the most common; PayPal, Authorize.Net, Square, and Braintree all appear in production engagements. The work covers subscriptions, one-time charges, invoicing, dunning, refunds, and dispute handling — with the idempotency keys and webhook handling that keep the integration from double-charging or dropping a payment.
What happens when a third-party API changes?
It will. APIs deprecate endpoints, change rate limits, and break backward compatibility. The integration is built with monitoring + alerting so failures surface fast, and the engagement handover includes documentation on how to update the integration when the vendor changes the contract. For ongoing maintenance, a retainer is the right shape.
Can you connect AI to our existing systems?
Yes — this is where API integration overlaps the <a href="/ai-automation-developer">AI automation developer</a> work. The pattern: webhook in from the source system, LLM-driven processing, structured update back to the destination system via API, audit log written. The integration discipline is the same; the LLM is just another vendor.
Do you offer ongoing maintenance for integrations?
Yes — a monthly retainer is the right shape for integration maintenance. The retainer covers monitoring response, vendor API change adaptation, new integration additions on a small scale, and the documentation updates that keep the integration runbook current.
