Coretech3 pairs deep SP-API and Advertising API experience with pragmatic cloud engineering so your team ships automation that survives real-world rate limits, edge cases, and audits.
Sellers and agencies shouldn’t gamble on fragile scripts or opaque vendors. Since 2020 we’ve aligned roadmaps around measurable outcomes—inventory truth, reconciliation you can defend, dashboards operators trust, and releases that roll forward safely.
SP-API ingestion (orders, catalog, feeds, finances, reports), Advertising API pipelines, Laravel / Node backends, React dashboards, Postgres data models, queues + workers, observability stacks, hardened AWS patterns, GDPR-aware handling for marketing integrations, agency multi-tenant rollouts—scoped to what you actually need next.
