Building Production Infrastructure for Nigeria's Capital Markets
Nigerian Exchange Group required enterprise-grade digital infrastructure to modernize share distribution across Nigeria's capital market. Herlabytes delivered a complete platform—architected, built, and maintained to handle national-scale financial transactions with zero tolerance for downtime.
Client: Nigerian Exchange Group
Sector: Capital Markets & Securities
Timeline: Design to production deployment
Our Role: Lead technology partner—architecture, implementation, and ongoing operations
The Results
1. Multi-Tenant Platform Architecture
We engineered a unified system serving distinct user classes—retail investors, institutional participants, issuers, registrars, and stockbrokers—each with role-based access, isolated data domains, and granular permissions. One platform, multiple audiences, zero data leakage.
2. Real-Time Transaction Engine
Built a high-throughput processing system capable of handling concurrent share subscriptions during peak public offer periods. Instant validation. Immediate confirmation. Real-time reconciliation across all market participants.
3. API-First Integration Layer
Designed and implemented a comprehensive API gateway enabling third-party platforms—mobile apps, fintech providers, USSD channels—to integrate directly with capital market infrastructure. Clean endpoints. Complete documentation. Production-ready from day one.
4. Enterprise Back-Office Systems
Developed sophisticated administrative tools for capital market operators managing the full lifecycle of public offers and rights issues—from listing to allocation to settlement. Complete visibility. Audit trails. Regulatory compliance built-in.
5. Investor Portal
A consumer-grade interface backed by enterprise-grade infrastructure. KYC integration. Payment processing. Instant brokerage lookup. Real-time portfolio tracking. Everything an investor needs to participate in the capital market.

Challenge: Integrate disparate capital market participants operating on legacy systems
Solution: Built robust API integrations with fallback mechanisms, data transformation layers, and comprehensive error handling
Challenge: Handle concurrent access during high-demand public offers
Solution: Implemented horizontal scaling, request queuing, and optimized database queries to maintain sub-second response times
Challenge: Maintain regulatory compliance across complex workflows
Solution: Architected audit logging, transaction traceability, and compliance reporting directly into system architecture
Challenge: Ensure zero financial discrepancies across distributed systems
Solution: Implemented idempotent transaction processing, distributed locks, and automated reconciliation checks
The Results
This platform became critical national infrastructure. When Nigeria's Central Bank mandated bank recapitalisation, the system we built enabled compliance at scale.
Every major bank that needed to raise capital used this platform. Not as one option among many—as the infrastructure that made digital share distribution possible.
The result: faster capital formation, broader investor participation, and a modernized capital market that actually works.
Ongoing Operations
Herlabytes continues providing operational support for NGX Invest—maintaining system performance, supporting capital market participants, and scaling infrastructure as transaction volumes grow.
This isn't a "launch and leave" project. It's production infrastructure we're responsible for keeping running.
What This Demonstrates
Herlabytes builds systems that handle real money at national scale. We understand financial services infrastructure not just the technical architecture, but the regulatory requirements, business logic, and operational realities that make or break production systems.
NGX Invest isn't impressive because it's complex. It's impressive because it works reliably processing billions in transactions while 200,000+ investors depend on it every day.
That's what enterprise software engineering looks like.
