Services
Three entry points: audit, build, or operate. Every engagement starts with a 45-minute technical diagnosis and a written proposal within 48 hours.
Advisory
3 to 5 working days
We review your APIs, authentication, timeouts, retries, webhooks, idempotency, logs, and monitoring. You leave with a Technical Integration Report: problems, risks, quick wins, target architecture, roadmap.
3 to 7 working days
From payment request to settlement: API, provider, webhook, transaction, ledger, reconciliation. You get an Architecture Assessment, a Risk Map, and a Technical Roadmap — plus a Payment Reliability Score.
3 to 5 working days
Current state, problems, risks, target architecture, migration roadmap. We work on your code, diagrams, and infrastructure — not a generic slide.
5 working days
Timeouts, retries, circuit breakers, observability, high availability, runbooks. You leave with a Production Reliability Report — what will break, how you will know, and how long recovery takes.
3 to 5 working days
OAuth2, JWT, RBAC, API gateway, secrets, webhook authentication, OWASP API Security. Findings ranked Critical / High / Medium / Low, with a remediation plan.
1 to 3 weeks depending on scope
Reduce response time and increase platform capacity: baseline, profiling, bottleneck identification, optimization, load testing, validation.
3 working days
We take one month of your real data — operator exports on one side, application transactions on the other — and produce the match. You get the exact gap and its origin.
5 working days
Before production: load testing, operator-outage scenarios, recovery plan, go-live checklist.
2 to 3 days
For investors and acquirers: an independent assessment of architecture, technical debt, and execution capacity of a financial-sector target.
2 days, on your premises
Integrate payments, secure an API, observe production — two days with your technical team, on your own cases.
Engineering
3 to 8 weeks depending on scope
Modernize legacy backend systems without breaking production: stack upgrades, modularization, API redesign, event pipelines, observability, resilience and cloud readiness. Deep JVM/Spring expertise — and pragmatic work on Node, Python and polyglot architectures when that is what production requires. Not a big bang. A path your teams can follow.
3 to 5 weeks
Wave, Orange Money, Free Money, card, bank transfer — wired cleanly into a single architecture.
2 to 4 weeks
Integrate a PSP, mobile-money rail, or payment rail into an existing platform: architecture, APIs, webhooks, idempotency, retries, transaction state machine, reconciliation, monitoring, tests, documentation.
Start within 48 hours
Payments collected on the operator side but missing from your system. Customers charged twice. We step in.
4 to 8 weeks
The system that tells you, every morning, exactly how much you collected.
6 to 10 weeks
One API for your teams, several providers behind it, with smart routing and automatic failover when an operator goes down.
8 to 12 weeks
Customer accounts, balances, deposits, withdrawals, internal transfers — on an auditable ledger.
Managed engineering
Monthly subscription, no minimum term
After an engagement: monitoring, fixes, small evolutions, architecture review, security, performance, and support during business hours.
Monthly retainer, no minimum term
A senior architect inside your team, without hiring one: architecture, backend engineering, payment integrations, code review, technical roadmap, mentoring, production support during business hours.
Annual retainer proportional to the covered scope
Fixes, adaptations to operator API changes, small functional evolutions.
Out of scope:
We analyse your needs and propose a tailored approach.
