Custom SaaS engineering
Multi-tenant databases with real row-level isolation, role-based access control your admins can configure themselves, and high-throughput REST or GraphQL APIs.

- GraphQL
- RBAC
- OpenAPI
Platform engineering · Contracted under SLA
We build the systems your business runs on, then keep them running.
Multi-tenant products, payment switches and cloud infrastructure for teams who want the architecture reviewed before the first sprint, not after the first outage.

Core technical modules
What we are asked to build, over and over.
Each one is scoped, estimated and delivered by the same team that reviews your database schema.
Cloud architecture & DevOps
Containerised services on managed Kubernetes, infrastructure defined in code, and CI/CD that deploys on merge with health-gated rollback.
- Docker
- Kubernetes
- Terraform
- Observability
Fintech & transaction systems
BBPS transaction switching, digital agent networks with commission ledgers, and merchant payment integration built for reconciliation from day one.
- BBPS
- Settlement
- Ledgers
- Audit trail
Applied AI & automation
Retrieval-augmented assistants grounded in your own documents, extraction pipelines, and orchestration that keeps a human in the loop.
- RAG
- Vector search
- Extraction
- Evals
Reference architecture
Every box ships as a container and rolls out through a pipeline.
A typical multi-tenant platform with a BBPS switch runs as an API gateway behind a CDN and WAF, fronting authentication, tenant services, the transaction switch and an orchestration layer for AI features.
Edge
CDN and WAF in front of a rate-limited API gateway. Nothing reaches a service without passing both.
Services
Auth and RBAC, tenant services, the BBPS switch and an LLM orchestrator — deployed and scaled independently.
State
Primary PostgreSQL with read replicas, Redis for cache and queues, object storage for documents and evidence.
Delivery
Health-gated rollout, automated rollback, and runbooks handed to your team at go-live.

Delivery methodology
How an engagement runs.
Four stages. You get a written deliverable at the end of each one, and you can stop after any of them.
Requirements audit
We map what exists, what it costs to run and where it breaks. The output is a written scope with assumptions listed and priced — not a proposal deck.
Schema & architecture review
Data model, tenancy boundaries, access control and integration contracts agreed before any production code is written. Changing this later is what makes projects expensive.
Sprint engineering & penetration testing
Two-week sprints with a working demo at the end of each. Security testing runs against staging before the release candidate is cut.
Production rollout & SLA support
Health-gated deployment, runbooks handed over, and a support agreement with named response windows for each severity level.
Recent work
Shipped and in production.
Client names withheld where the engagement is under NDA.
2026 · FintechAgent network with BBPS switching
Commission ledger, settlement reconciliation and merchant onboarding across a distributed retail agent network.
2026 · SaaSMulti-tenant operations platform
Role-based access across regional branches with tenant-level data isolation and an audited change history.
2025 · AutomationDocument extraction pipeline
Invoice and compliance intake with retrieval-grounded review and human approval before commit.
Already running something that breaks under load?
We take on inherited systems. The audit stage stands alone — you get the findings whether or not we do the rebuild.
