Microsoft 365 built by native engineers
Integrate Outlook, Teams, SharePoint, and OneDrive — plus AI copilots built on Microsoft Graph.
What Microsoft 365 Integration Services looks like with us
Engineer Master Labs delivers Microsoft 365 for teams that need results in production, not slide decks. We structure work around your existing engineering cadence — Slack or Teams channel, weekly demos, shared backlog. Security and privacy are built in: NDA-first, least-privilege IAM, EU or US data residency, VPC-isolated deployment options. Our engagement models flex to your stage: fixed-scope, staff augmentation, or monthly retainers.
- 01Webhook handlers, signature verification, replay safety
- 02Version-pinning strategy and migration runbook when APIs change
- 03Native SDK integration — not a hand-rolled HTTP wrapper that breaks on API changes
- 04Retry / backoff / timeout strategies and dead-letter queues
- 05Observability: per-call latency, token usage, cost attribution
How teams use this

Common questions
What happens when the upstream API changes?
We pin versions, monitor provider changelogs, and run regression tests against known inputs. When a breaking change lands, we estimate and quote the migration.
How do you handle rate limits and outages?
Retries with exponential backoff, circuit breakers, dead-letter queues, and where appropriate a secondary provider fallback. We instrument everything so you see outages in real time.
Who owns the IP?
You do. All code, documentation, model weights, and deliverables are assigned to you on payment. Our master service agreement spells this out explicitly.
Do you sign NDAs before a scoping call?
Yes — standard practice. We circulate a mutual NDA before any detailed conversation about your product, data, or roadmap.
