Custom SaaS Product Engineering

Multi-tenant platforms where the tenancy model is an architectural decision taken deliberately at the outset. Isolation strategy, per-tenant data residency, noisy-neighbour control and tenant-scoped observability are specified before the first feature is built, because none of them can be added cheaply afterwards.

What you get from the engagement

A tenancy model that holds at your projected tenant count, not just your current one
Per-tenant usage metering suitable for billing
Tenant onboarding measured in minutes rather than engineering days
Isolation you can evidence to a security reviewer

Technical capabilities

What we do inside it

Tenancy and data isolation strategy
Subscription, entitlement and feature-flag architecture
Per-tenant metering and usage aggregation
Administrative and tenant-support tooling
Load, soak and multi-tenant performance testing

Architecture and stack

How we build it

Architectural position

Tenant identity is resolved in middleware and enforced at the query layer, so a missing scope is a failing test rather than a cross-tenant data leak.

Representative technologies

Technology selection follows the requirement. This list is representative of engagements in this service line, not a constraint we impose on yours.

Service assurance

SLA, compliance and governance

Engagements in this service line are delivered under the Platinum service tier by default, against the compliance obligations below. Both are set in the engagement contract, not by this page.

Default tier

Platinum — 99.95% availability target, P1 response within 15 minutes, coverage 24 × 7 × 365.

Compliance scope

Governance

Written architecture decision records, weekly delivery reporting, and a documented handover comprising runbooks, source and credential transfer at engagement close.

Intellectual property

Client-commissioned work product vests in the client on payment. Source escrow available on request.

Service level tiers, availability targets and response commitments
Tier	Availability target	P1 response	P1 resolution target	Coverage	Service credits
Platinum	99.95%	15 minutes	4 hours	24 × 7 × 365	Yes
Gold	99.9%	1 hour	8 hours	24 × 5 plus on-call	Yes
Silver	99.5%	4 hours	2 business days	09:00–18:00 EAT	No

Publication gate G-05 — outstanding

These values illustrate the structure of the table. Each figure must be confirmed by whoever will be contractually bound by it, and the availability targets must be achievable on the underlying cloud provider SLAs before publication. Publishing a 99.95% target on infrastructure whose own composite SLA is lower creates an obligation that cannot be met.
