API & Integration
Architecture
Enterprise API design, microservices decomposition, and integration patterns derived from 10 years of operating a high-throughput, multi-tenant validation platform at scale.
Addresser's own platform processes millions of validation calls across a multi-tenant FastAPI services architecture with clean workstream separation, carrier adapter patterns, and strict architectural constraints that prevent technical debt accumulation. We bring these production-proven patterns to your integration challenges.
API Design & Governance
RESTful API design standards, versioning strategies, authentication patterns (OAuth 2.0, API keys, JWT), and documentation standards that make APIs maintainable at enterprise scale.
Microservices Decomposition
Domain-driven decomposition of monolithic applications into services with clean boundaries. Service mesh, inter-service communication, and distributed transaction strategies.
Integration Architecture
Enterprise integration patterns — event-driven, ETL/ELT, API mesh, and pub/sub designs. Platform adapter patterns that isolate third-party dependencies.
API Security Architecture
Rate limiting, PII masking, tenant isolation (Row-Level Security, schema-per-tenant), and secrets management via AWS Secrets Manager.
Cloud-Native API Infrastructure
AWS and Azure API infrastructure design — private networking, CI/CD pipelines, and zero-downtime deployment for production APIs.
API Observability & SLAs
Monitoring, alerting, and SLA framework design. Defines p50/p95/p99 latency targets, error rate thresholds, and runbook processes.
