Cloud Native Application Development & Modernisation

Si Novi is a UK-based AWS Select Tier Services Partner specialising in cloud-native application development. We work directly with product teams and business stakeholders to design, build, and maintain web and mobile applications on AWS.

Our engagements span the full application lifecycle:

Assessment and Architecture We begin with technical discovery, event storming, and story mapping to understand your requirements. We design AWS architectures using Well-Architected principles, providing clear blueprints and delivery roadmaps before development begins.

Greenfield Development We build new applications using serverless (Lambda, API Gateway, DynamoDB, Step Functions), containerised (ECS, Fargate), or hybrid architectures depending on your requirements. Our frontend work covers React, Enhance.js, and React Native with Expo for cross-platform mobile.

Legacy Modernisation We modernise LAMP and other legacy stacks by incrementally migrating to managed AWS services. As a team with deep open-source roots in PHP, JavaScript, and Python, we understand legacy applications from the inside and focus effort where it has the most impact.

AI and Generative AI We integrate Amazon Bedrock and Retrieval-Augmented Generation (RAG) into web applications, enabling conversational interfaces, document analysis, and intelligent search backed by your own data.

Media and Content Delivery We build high-performance media delivery pipelines using CloudFront, S3, WAF, and Lambda@Edge for organisations where fast, secure content delivery is business-critical.

DevOps and Infrastructure as Code We implement CI/CD pipelines, Infrastructure as Code with CloudFormation or Terraform, and DevSecOps practices that integrate security scanning into your delivery workflow.

Our client relationships are long-term partnerships. We have supported clients including Jaguar Land Rover continuously for over a decade, and have delivered projects across automotive, media, construction, sustainability, and professional services sectors. Notable projects include a global motorsport app for SRO Motorsports Group, a multi-tenant SaaS platform for Spacesuit Media, and an offline-capable Progressive Web App for site surveying on the HS2 infrastructure project.

AWS services we commonly work with: Lambda, API Gateway, DynamoDB, RDS, Aurora, ECS, Fargate, CloudFront, S3, Step Functions, SQS, SNS, EventBridge, Cognito, WAF, ACM, CloudFormation, CodePipeline, Bedrock, CloudWatch, X-Ray.
