Full Stack Development in Edinburgh
Edinburgh's finance sector and broader SME base of 25,000 businesses increasingly require custom software to manage complex operations, serve customers digitally, and integrate AI capabilities that off-the-shelf platforms cannot provide. Aristral builds full stack applications for Edinburgh businesses: production-grade Next.js frontends, Python and Node.js backends, and AI-integrated systems with RAG retrieval, background workers, and LLM observability from day one. We serve Edinburgh and across Scotland, delivering with CI/CD pipelines, automated tests, and handover documentation that your engineers or future partners can extend without tribal knowledge.

Full Stack Development for Edinburgh Businesses
Full stack development for Edinburgh businesses starts with understanding the commercial outcome the software needs to deliver, not the technology. We assess whether an off-the-shelf platform solves the problem better than a custom build — and we are honest when it does. When custom development is warranted, we build with Next.js App Router for SEO-aware, performant frontends; Python or Node.js for backend services; PostgreSQL and Redis for data persistence; and Pinecone or pgvector when AI retrieval features are required. Security is scoped at sprint one: OWASP-aligned input validation, secret management via environment vaults, least-privilege access controls, and dependency scanning in CI pipelines. For Edinburgh businesses in regulated sectors — finance, healthcare, legal — we produce DPIA-aligned data-flow documentation and support vendor security questionnaire completion. AI-integrated features for Edinburgh clients — RAG chatbots, LLM-powered classification, document processing pipelines — are designed to be testable and observable, not black-box integrations. Every Edinburgh full stack engagement delivers architecture diagrams, environment variable documentation, and runbooks so your future hires can extend the system without depending on the original development team.

Frequently Asked Questions
How much does custom software development cost for a Edinburgh business?
Custom software development for Edinburgh businesses typically ranges from £15,000–£40,000 for focused MVPs with well-defined scope to £40,000–£150,000 for multi-feature platforms with complex integrations. We scope fixed phases after a paid discovery engagement so you fund incrementally with written milestones and acceptance criteria.
How long does a full stack development project take for Edinburgh clients?
MVPs typically require 8–16 weeks from signed specification to launch. More complex platforms with multiple integrations take 16–32 weeks. We provide a written project timeline after discovery that reflects the actual scope, not optimistic assumptions.
Do you work with existing codebases for Edinburgh businesses?
Yes. We audit existing codebases for quality, performance, security, and AI integration readiness, then build on or refactor the existing system as appropriate. Every codebase audit produces a written assessment with prioritised technical debt recommendations.
Can you build AI features into our Edinburgh business software?
Yes — AI integration is a core specialisation. We build RAG retrieval systems, LLM-powered features with guardrails and observability, and background document ingestion workers. AI features are designed as testable production software, not demo integrations that fail silently.
What handover documentation do you provide to Edinburgh clients?
Every Edinburgh full stack engagement delivers architecture diagrams, API contracts, environment variable documentation, data flow diagrams, and runbooks for common maintenance tasks. Handover includes pairing sessions with your team so they feel confident extending the system without ongoing dependency on us.
