Live transaction rails
Mobile money, card and bank-transfer settlement in production, with reconciliation and dispute handling — not a sandbox integration.
Enterprise technology division — Jiranisoko Market Ltd
We build the platforms institutions run on.
Jiranisoko Tech Solutions architects, engineers and operates artificial intelligence, cloud infrastructure and transaction-grade software for financial institutions, public-sector agencies and high-growth enterprises. Our standards are set by the systems our own group depends on every day.

The group behind the engineering
We do not only build platforms. We operate them.
Jiranisoko Tech Solutions is the technology division of Jiranisoko Market Ltd, a holding company with operating interests across multiple digital verticals. Chief among them is JiraniSoko Marketplace — a consumer marketplace carrying live M-Pesa payment rails, live fraud exposure and a live uptime obligation to the people trading on it.
This distinction matters to any institution evaluating an engineering partner. A consultancy that has never carried an on-call rota for its own revenue-bearing system is proposing architecture it has not been accountable for. We carry that rota. The disciplines we sell — observability, incident response, capacity planning, payment reconciliation, PCI scope control — are the disciplines that keep our own group solvent.
Proof 01
Proof 02
Continuous operation
A production system with a defined recovery objective, tested restores and a documented incident record.
Proof 03
Adversarial pressure
Real fraud, real abuse, real scraping. Our security posture is shaped by attacks we have actually absorbed.
Capability taxonomy
Six engineering disciplines. One accountable delivery organisation.
Enterprise programmes rarely sit inside a single discipline. A payments modernisation is a cloud migration, an API engineering effort and a compliance exercise at the same time. We structure our practice so that one engagement can draw on all six without a change of vendor, contract or accountability.
Pillar 01
Artificial Intelligence & Automation
We move organisations from AI ambition to production systems that carry measurable operational load — with the evaluation, guardrails and human oversight that make them defensible to a risk committee.
- Agentic AI & Autonomous Agent Architectures
- AI Readiness Assessment & Enterprise AI Strategy
- Enterprise Copilots & Conversational Assistants
- LLM Fine-Tuning & Private Model Deployment
- AI-Driven Workflow Automation & Process Optimisation
Cloud Infrastructure & DevOps
We design and operate cloud estates that are auditable, reproducible and cost-governed — where every environment is defined in code, every change is reviewable, and every deployment is a non-event.
- Cloud & Data Migration Services
- Cloud Strategy, Architecture & Consulting
- Enterprise DevOps, CI/CD Automation & Infrastructure as Code
- Serverless Architecture & Microservices Engineering
Enterprise Software & SaaS Solutions
We engineer multi-tenant products and internal platforms built to survive their own success — tenancy isolation, data partitioning and reporting designed in from the first sprint rather than retrofitted under load.
- Real-Time Auction & Trading Engine Platforms
- Business Intelligence, Analytics & Executive Dashboards
- Enterprise Mobile Application Development
- Custom SaaS Product Engineering
Financial Technology & Payment Ecosystems
We build the money-movement layer: integration with mobile money and card rails, reconciliation that balances, and cardholder-data architectures scoped for audit from the first day rather than the first assessment.
- Institutional Billing, Invoicing & Subscription Engines
- Payment Gateway Integration & Custom Gateway Development
- Core Transaction Processing & PCI-DSS Compliant Architecture
Core Frameworks & API Engineering
We modernise the systems institutions already depend on, and expose them through interfaces that are versioned, contract-tested and defensible under security review.
- High-Performance Angular Web Applications
- API Design, Integration, Testing & Security Audit
- Enterprise Microsoft .NET Development & Modernisation
Decentralised Web3 & Blockchain Engineering
We apply distributed ledger technology where it demonstrably outperforms a database — multi-party settlement, provenance and asset tokenisation — and we say so plainly when it does not.
- Enterprise Blockchain & Private Distributed Ledgers
- Smart Contract Architecture & DeFi Protocols
- Web3 Application Ecosystems & Asset Tokenisation
How we are engaged
Three contracting structures. Chosen by your risk position, not by our preference.
Where the scope is definable and the outcome is fixed, we carry the delivery risk. Where the scope will evolve and your team must own the result, we embed senior engineers inside your organisation. Where the decision precedes the build, we advise and step back.
Model A
Turnkey Solution Delivery
Fixed-scope, end-to-end accountability. We take the requirement through architecture, engineering, security review, deployment and SLA-governed operation, and we are answerable for the outcome.
- Commercial basis: Fixed price, or capped time-and-materials against an agreed scope baseline. Change is handled through a written variation rather than absorbed silently.
- Suited to: Defined programmes with a hard delivery date and an internal team without the capacity to execute them.
Dedicated Engineering Teams
Senior engineering pods integrated into your workflow, your board, your standup and your definition of done. You direct the work; we own recruitment, retention, bench cover and technical quality.
- Commercial basis: Monthly per-seat retainer with a ninety-day minimum term and thirty days notice to scale down.
- Suited to: Product organisations scaling faster than they can hire, working to an evolving roadmap.
Enterprise Strategic Advisory
Independent architectural, security and transformation counsel — including the assessment of work we did not build and would not be asked to rebuild.
- Commercial basis: Fixed-fee assessment against a defined question, or retained advisory days drawn down monthly.
- Suited to: Boards and chief information officers who need a defensible basis for a major technology decision.
Unsure which applies? Our intake determines it in four questions.
Operating headquarters — Eldoret, Kenya
Global engineering standard. Regional economic advantage.
Our location is a deliberate operating decision, not a concession. Eldoret gives us access to a deep, university-fed engineering base at a cost structure no Tier-1 city can match, in a time zone that overlaps the working day of every market we serve. What does not change with geography is the standard: the same architecture review, the same security gates, the same test discipline, the same code we would ship from anywhere.
The Gulf, continental Europe, the United Kingdom and South Asia all fall within a six-hour or better daily overlap on standard hours. The United States East Coast does not: on 08:30–17:30 EAT the overlap is 1.5 hours, extending to approximately 3.5 hours where an engagement is staffed on a staggered afternoon shift. We state that arrangement in the engagement terms rather than implying it here.
Publication gate G-04 — outstanding
Advantage 01 currently states a cost advantage without a figure, because no comparison basis has been supplied. Before launch, either publish the rate differential with its basis (role, region, period) recorded against the metric, or leave the qualitative statement as written. Do not publish a percentage without the basis behind it.
Governance, compliance and service assurance
Contractual commitments, not aspirations.
Every engagement is governed by a written service framework covering security controls, availability targets, data protection obligations and intellectual property transfer. These terms are available for review before contract, and our security documentation is released to prospective clients under non-disclosure agreement on request.
Security
Security posture
Information security management aligned to ISO/IEC 27001. Role-based access with least privilege, mandatory code review, dependency and secret scanning in CI, annual penetration testing, and a published responsible-disclosure channel.
Availability
Service levels
Three contracted tiers with defined availability targets, severity-based response commitments and a service-credit regime. Measured monthly, reported to the client, and reconciled at quarterly service review.
Data
Data protection
Processing governed by a Data Processing Addendum meeting the Kenya Data Protection Act 2019 and GDPR Article 28 requirements. Data residency is selectable by region; sub-processors are disclosed and change-notified.
Continuity
Intellectual property and exit
Client-commissioned work product vests in the client on payment. Source escrow available on request. Every engagement concludes with a documented handover: architecture records, runbooks and credential transfer.
| 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.

Engineering note
Scope is the only PCI decision that matters
Most of the cost of a PCI programme is decided at design time, by how much of the estate falls inside the boundary.

A distributed ledger earns its complexity only when no single participant can be trusted to hold the record.

Retrieval that ignores per-user access turns an assistant into a data breach with a friendly interface.
4 min read →Request for Proposal
Begin with a scoped conversation, not a sales call.
Our intake is structured so that the first response you receive is technical. Tell us which of the following describes your position and we will route your enquiry to the engineering lead who owns that practice.
Enterprise modernisation
An existing system — core, legacy or on-premises — that must be migrated, re-architected or integrated.
New product build
A platform to be taken from concept or specification to production under a fixed scope.
Team augmentation
Senior engineering capacity embedded into an existing team and roadmap.
Enquiries are acknowledged within one business day and answered substantively within two business days. All submissions are treated as confidential; a mutual non-disclosure agreement is available before disclosure of scope.
