Telephony, e-signatures, payments, maps and third-party data, wired into your product properly.
A lot of product work is connecting things that were not designed to connect. We have built against carrier SMS gateways, PKCS#7 signing, Stripe, mapping and tile services, property-data feeds, calendar and CRM APIs, and we design public APIs of our own. We can build the integration, or the API that other people integrate with.
What you get
- 01Integration design with failure modes, retries and idempotency specified up front
- 02Webhook delivery with signing, logging and replay
- 03Public API design, reference documentation and client examples
- 04Migration from an existing vendor, including compatibility shims
- 05Load and cost modelling against real traffic
Engagement
- Fixed-scope build
- A written scope, a fixed quote, a delivery date. Best when the problem is understood and the outcome can be described in a page.
- Retainer
- A monthly allocation for continuous work: integrations, agents, features, maintenance. Quoted per month against an agreed cadence.
Quoted against a written scope. No hourly rates, no published prices.

All work →Questions people ask first
- Can you replace a vendor without downtime?
- Usually. AiroSign was built to be a drop-in for DocuSeal for exactly this reason. We plan cutovers with parallel running and a rollback.
