Software Systems Consulting for Complex Enterprises
We design, build and deploy mission-critical software systems for organisations operating in complex environments — where reliability, data integrity and long-term maintainability are non-negotiable.
Headquartered in Nigeria, serving clients across Africa and beyond.
What We Build
Three practice areas. All delivered with the same rigour and attention to long-term quality.
Software Systems
We design and build production-grade software systems for organisations with complex operational requirements — custom-engineered to your processes, integrated with your existing infrastructure, and built to last.
Data-Driven Decision Making
We turn operational data into a strategic asset. From dashboards and reporting layers to intelligent monitoring and analytics pipelines — we help organisations make better decisions, faster, with confidence in the numbers.
Software Systems at Scale
We architect and deliver software that grows with your organisation — handling higher volumes, more users and greater complexity without requiring a rebuild. Performance and resilience are first-class concerns from day one.
Trusted by industry leaders
How We Deliver
Every engagement starts with deep discovery. We map your processes, your pain points, and your constraints before proposing a single technical solution — because the right architecture depends entirely on the real-world context it must serve.
- check_circleRequirements mapped to technical architecture before a line is written
- check_circleCustom-built — no off-the-shelf templates forced onto your processes
- check_circleFull source ownership, documentation and post-launch handover
Built in Nigeria.
Trusted internationally.
Founded in 2021, Outlier Technologies is a software systems consultancy delivering enterprise-grade applications for private and public sector clients. We build custom software that manages complex operations, structures organisational data and scales reliably — for institutions where the software has to work.
What makes us different is the weight we place on correctness, performance, and longevity. We don't prototype and pivot — we architect and deliver. Every system we ship is designed to run without hand-holding, in environments where failure is not an option.
Our Journey
Founded
Outlier Technologies was established with a clear mandate: build software systems that actually work — for organisations in Nigeria and across Africa that needed enterprise-grade technology without enterprise-grade bloat.
Product Delivery Across Sectors
Shipped multiple software products for private and public sector clients — including full ERP implementations for logistics and government agencies, and proprietary anomaly detection systems for financial and operational use cases.
International Expansion
Extended our consulting and delivery practice beyond Nigeria, serving clients across multiple African countries and internationally. Our systems now operate in environments spanning fintech, public infrastructure, manufacturing and professional services.

Have a complex system that
needs to actually work?
Whether you're dealing with legacy system constraints, data visibility problems, or building something critical from scratch — let's have a direct conversation about what you need.
Software Systems Consulting
for Organisations That Need It to Work
We design, build and deploy software that handles the full complexity of your operations — from bespoke business systems to large-scale data platforms. No templates. No cut corners. No hand-waving about “scalability” without the architecture to back it up.
Services
Deep specialisation across the full enterprise software stack — from requirements through to production operations.
Business Software Systems
Custom software built around your operational model — not the other way around. We engineer systems that manage complex business processes, unify fragmented workflows and integrate cleanly with your existing technology landscape.
- Public sector & government
- Manufacturing & logistics
- Financial services
Data & Intelligence Platforms
We build the data infrastructure that turns operational output into insight — monitoring layers, analytics pipelines and reporting systems designed for organisations making high-stakes decisions.
Systems Architecture
Technical blueprints that survive contact with reality. We design for scale, for maintainability, and for teams that will inherit the codebase.
International Delivery
Proven track record delivering software across Nigeria and beyond — with teams, processes and support structures built for cross-border programmes.
Three Engagements. Three Industries. One Standard.
Each project below required us to reason from first principles — designing for the specific constraints of the domain, not retrofitting off-the-shelf templates.
PropFlux — High-Throughput Property Listing Data Platform
Architecting an event-driven ingestion backbone that processes 10,000+ listings with guaranteed schema integrity
The Challenge
A growing property marketplace was ingesting listings from five disparate agent networks — structured CSV exports, unstructured WhatsApp-forwarded text, scraped HTML tables and REST webhook payloads — with no canonical data model enforcing field completeness or type safety. Duplicate listings crossed sources, geospatial queries ran full-table scans on 90,000-row PostgreSQL tables with no spatial index, and the image pipeline was a synchronous bottleneck that blocked listing publication for up to 8 minutes. The system had no retry logic, no dead-letter handling, and zero observability into the state of any in-flight record.
Our Approach
We rebuilt the ingestion layer as an asynchronous, queue-backed pipeline using BullMQ on Redis. Each source adapter normalises raw payloads into a canonical listing schema — validated at the boundary with Zod before any persistence — and enqueues a job. Workers pick up jobs concurrently (configurable concurrency per source tier), apply deduplication via a composite fingerprint hash, and commit to PostgreSQL using Prisma transactions with optimistic locking. PostGIS GIST indexes on geometry columns dropped geospatial radius query latency from 4.2 s to 68 ms at the 99th percentile. The image pipeline became a separate worker pool: each job dispatches to Cloudinary's Upload API with server-side transformation presets (WebP/AVIF, five responsive breakpoints), then writes CDN URLs back via an UPDATE without blocking the listing record. A custom BullMQ dashboard middleware streams queue depth, throughput, and failure rates as Server-Sent Events to an internal ops panel. Failed jobs are routed to a dead-letter queue with full error context and auto-retried with exponential back-off up to five times.
