SaaS & API Development

Q: What stacks do you use for SaaS and APIs?

We commonly ship Node/TypeScript or Python services with PostgreSQL and Redis, REST or GraphQL as the contract, and OpenAPI docs. We match your existing stack when that is the faster path.

Q: Do you work with legacy APIs?

Yes. We modernize or wrap legacy SOAP/REST systems with stable interfaces so new products are not blocked by undocumented endpoints.

Q: How do you ensure API security?

Modern auth (OAuth2/JWT/SSO as appropriate), input validation, rate limiting, token lifecycle controls, and OWASP API Security practices are part of delivery—not optional extras.

Q: Can you document our existing API?

Absolutely. Producing OpenAPI specs and developer-friendly docs is a first-class deliverable, including for APIs we did not originally build.

Q: How fast can an integration ship?

Focused integrations often ship in under 10 business days once credentials, environments, and acceptance criteria are ready. Broader SaaS backends typically land in the 2–6 week range.

Q: Will partners be able to self-serve against our API?

Growth and Scale packages include partner-ready documentation, versioning guidance, and auth patterns so partners are not blocked on one-off email threads.

Q: What about payments and third-party SaaS?

Stripe, PayPal, HubSpot, Shopify, Airtable, ClickUp, Notion, and Meta APIs are common. Scope lists exact vendors and sandbox vs production cutover in the proposal.

The friction

What slows you down

Critical tools do not share data, so teams live in export/import loops
Partner onboarding stalls because there is no clear API contract
Fragile spreadsheet or Zapier bridges break under real volume
Auth and permissions are inconsistent across internal apps
No monitoring when an integration fails—customers notice first
Legacy SOAP or undocumented endpoints block modern product work

What changes for you

What you get instead

Integrations ship in under 10 business days, so your tools share one source of truth
Documented REST and GraphQL APIs replace fragile spreadsheet handoffs between systems
Partners onboard against a spec instead of waiting on a custom one-off

Capabilities

What we build into every engagement

REST, SOAP, GraphQL API development & integration
Webhooks, real-time event processing, queue-based systems
OAuth2.0, JWT, SSO, multi-provider authentication flows

Payment gateway integrations (Stripe, PayPal)
Third-party SaaS integrations (HubSpot, Airtable, ClickUp, Notion, Meta APIs)
Custom API creation for mobile apps, dashboards, external partners

API security hardening (rate limiting, token lifecycle, IP restrictions)
API versioning, documentation, monitoring, analytics

Packages

Scoped shapes for how we engage. Every build is quoted to your brief after a short discovery call.

Essentials

Single integration or microservice

OpenAPI spec for the agreed surface
Auth plus 3–5 production endpoints
Basic monitoring and error alerting

Best for Single system integration or MVP backend slice

Growth

Popular

Multi-system integration

10–15 endpoints across systems
Webhooks with retries and idempotency where needed
Caching and rate limiting
Partner-ready documentation

Best for Product teams shipping partner or vendor integrations

Scale

High-traffic, enterprise-ready APIs

Service architecture suited to growth
Observability (logs, metrics, traces)
Zero-downtime deploy practices
SLA and support plan options

Best for Complex platforms with strict reliability needs
