Cloud-native architecture, distributed systems, and enterprise .NET solutions. We turn complex engineering challenges into reliable, high-performance software.
From architecture to delivery — we cover the full engineering lifecycle for enterprise and cloud-native systems.
Technical strategy, architecture reviews, and hands-on engineering leadership. We help organisations build better systems, stronger teams, and engineering practices that last.
Design and deploy scalable cloud-native solutions on Microsoft Azure. Infrastructure as code, PaaS/IaaS patterns, cost optimisation, and enterprise-grade reliability.
Build event-driven, high-throughput systems with Kafka, microservices patterns, and async messaging. Designed for resilience, observability, and horizontal scale.
Enterprise-grade backend systems built with .NET and C#. High-performance APIs, complex domain models — clean architecture, CQRS, and DDD applied where they add real value.
High-performance financial systems built to strict reliability and compliance standards. Payment processing, transaction ledgers, and real-time data pipelines at scale.
Global-scale eCommerce platforms built for performance and reliability. Inventory systems, order management and processing pipelines, cross-border duty and tax calculation, and integrations that hold up under peak traffic without breaking.
A selection of complex engineering challenges solved across FinTech, eCommerce, and enterprise software.
Led migration of a monolithic eCommerce platform to microservices on Azure, cutting infrastructure costs by 40% and enabling daily deployments across international markets.
Built an event-driven data platform using Kafka and Azure Event Hubs to unify streams across 20+ internal services, enabling real-time analytics and operational visibility.
Designed and delivered a high-throughput payment processing system handling millions of transactions per day with sub-100ms latency and 99.99% uptime SLA.
Lagan Software Solutions is led by Software Engineers with over 20 years of experience designing and delivering high-performance, cloud-native solutions across the Microsoft technology ecosystem.
We've worked across FinTech, global eCommerce, cloud services, enterprise software, and the energy and renewables sector — leading teams and building scalable distributed systems where reliability and business value go hand-in-hand.
Our approach is simple: we take ownership, solve the right problems, and get things shipped. No over-engineering, no hand-waving. Just software that is reliable, maintainable, and delivers business value.
Consistent ownership from architecture to production. We take responsibility and get things shipped.
Systems designed for today's load and tomorrow's growth — built right the first time.
Dedicated support engineers, SLA-backed response times, and proactive monitoring so you can focus on your business, not your infrastructure.
Keep your software healthy and growing. Ongoing maintenance packages cover updates, performance tuning, security patches, and feature additions as your product evolves.
