Services

Custom, tailored engineering for companies of every size.

Every engagement starts with architecture and security, not just a feature list. Below is the full range of what 20 years in software development covers — from foundational systems work to the finishing details.

Core engineering services

Software Architecture & Systems Design

The structural decisions that determine whether a system scales cleanly or collapses under its own weight — bespoke architecture and custom programming tailored to your specifications.

Database Design & Data Architecture

Schemas and data models built for integrity and performance, plus data centralization solutions that bring documents, files and records into one organized system.

Security & Privacy-First Engineering

Industry-standard security and custom encryption built into every application from the start — server hardening, strict permission hierarchies, custom firewall configuration, and SSL/HTTPS by default, plus secure shopping-cart and payment flows engineered against fraud.

Full-Stack Web & Application Development

Dynamic websites and web applications with sign-in, registration, and account management, built end to end for your users and your business.

Enterprise Administration Portals & CMS

Centralized, secured admin portals and self-service content management systems, including a custom multilingual engine for managing content across languages.

Infrastructure & Networking

6+ years administering production Linux (Debian/Ubuntu) environments — multi-tier Live/Test/Dev pipelines over OpenVPN, performance upgrades (an SSD migration once cut heavy report runtimes by an hour), servers, workstations, firewalls and network security for organizations of any size.

Website Maintenance & SEO

Ongoing monitoring and enhancements (most changes that don't affect the site's look come at no charge), plus SEO strategy to improve visibility and ranking.

Additional capabilities

Beyond core software engineering, a few specialized services round out what's on offer.

Security Auditing & Penetration Testing

Vulnerability scanning and security audits — OWASP ZAP and similar tooling — to find and fix weaknesses before anyone else does.

Automation & Hardware Integration

Web applications connected to physical hardware — Raspberry Pi and similar devices — for custom automation.

AI & LLM Integration

Practical AI built into existing applications and workflows — chatbots, automation, and LLM-powered features, not just a demo.

3D Modelling & Web3D

3D modelling and Web3D/WebGL work for interactive product visualizations and browser-based 3D experiences.

Graphic Design & Brand Identity

Logo design and corporate identity — colors, typography and visual language — plus marketing materials like flyers and banners.

What happens after launch

Most engagements don't end at launch — here's what's included afterwards, and what counts as a new piece of work.

Monitoring & small fixes

Keeping an eye on the live application and handling small changes and bug fixes that don't touch its design.

Security & dependency updates

Frameworks, plugins and server software kept patched and current.

Backups & recovery

Routine backups, so a bad deploy or server issue is never a full rebuild.

Direct access to the person who built it

No ticket queue or account manager — enquiries go straight to me, reviewed personally within one business day.

New features, a redesign, or anything that meaningfully changes what the system does is scoped and quoted separately, agreed before any work starts — never a surprise on an invoice.

Not sure what you need?

Tailor-made services are the norm here, not the exception. Reach out before any commitment and we'll figure out the right scope together.
