Consulting Rates & Estimation Guide
We work with engineering departments through clear project-based architecture sprints, fixed-fee diagnostic audits, and monthly advisory retainers. All figures are informational and scoped to specific technical complexity.
OpenAPI Governance Audit
A fixed-duration 10-business-day deep architectural review of existing API surfaces, error codes, and linting rules.
- Comprehensive 30+ page Quality Scorecard
- Custom Spectral CI configuration repository
- 2-hour live executive & squad technical debrief
Contract Design Engagement
Full-cycle interface modeling, OpenAPI 3.1 schema authoring, RFC 7807 error modeling, and mock server deployment (3 to 6 weeks).
- Production-ready OpenAPI 3.1 schema bundle
- Idempotency & distributed transaction specifications
- Cross-functional consumer review sessions
Principal Advisory Retainer
Ongoing architectural oversight, weekly contract PR reviews, breaking-change risk triage, and office hours for your engineering leads.
- Up to 15 API pull-request contract reviews per month
- Bi-weekly architecture sync with engineering leads
- Direct Slack / Teams advisory channel access
How We Calculate Project Estimates
Because software architectures differ widely in domain density and protocol diversity, we calculate formal proposals based on three transparent technical dimensions:
1. Endpoint & Schema Surface
The total volume of discrete domain resources, mutation paths, query filter parameters, and polymorphic JSON schemas required.
2. Consumer Diversity
The number of independent consumer clients (web single-page apps, native iOS/Android, internal microservices, external B2B partners) that rely on contract stability.
3. Legacy Constraint Density
Whether the engagement is a greenfield API contract or requires backward-compatible adapter modeling over legacy relational databases and monolith backends.
Commercial & Billing Questions
Are initial discovery consultations billed?
No. We conduct an initial 45-minute technical discovery call at zero cost to review your current architecture diagrams and confirm whether our practice is the right fit.
What currencies and payment terms do you support?
Invoices are issued in either US Dollars (USD) or New Taiwan Dollars (TWD) via standard international wire transfer. Project sprints follow a 50% commencement deposit and 50% milestone completion schedule.
