Services

Software services for businesses

Digital transformation, done properly: businesses that run on scattered tools move onto coherent digital systems. Bespoke software, web development, business systems, monitoring & control, integrations, AI and modernisation — scoped around the actual operational requirement and delivered with direct technical ownership and AI-augmented engineering.

Build & deliver

Bespoke software development

Custom software for business processes that off-the-shelf products cannot serve.

  • Prototyping & proof-of-concept — validate before the full build
  • Custom web applications & platforms
  • Native desktop applications
  • Internal business software
  • APIs and system-to-system services
  • Technically demanding development work

Web development & online shops

Business websites, e-commerce and payments that work for the way you sell.

  • Business websites & web platforms
  • Online shops & e-commerce
  • Payment integration (Stripe, GoCardless, PayPal)
  • Course & booking platforms with payments

Business systems, data & reporting

Operational workflows and business processes in one coherent system — with dashboards and reports built around real operational questions.

  • Client portals & admin panels
  • Internal tools & operational software
  • Dashboards & KPI reporting
  • Automated & scheduled reports
  • Consolidating scattered data sources
  • Replacing spreadsheets and scattered tools

Operational monitoring & control

Know what your equipment is doing, act on it safely, and keep the record — a system for sites, devices and operations that goes past dashboards into decisions, actions and accountability.

  • Monitoring across sites, devices & equipment
  • Reading equipment over standard protocols — meters, inverters, sensors and PLCs
  • Safe remote action where the equipment supports it — with confirmation, not blind commands
  • Health signals & alerts — know what needs attention, and why
  • Long-term storage with tiered retention & rollups — the record, kept
  • Remote diagnosis & evidence — buffered device logs, what was done, and the outcome

Kiosk & self-service device software

Touchscreen kiosks and unattended devices that run their own operation — ordering, check-in, signage, customer information — without a person behind them.

  • Kiosk software on Linux-based hardware — e.g. Raspberry Pi + touchscreen
  • Customer apps on tablets & phones — installable web apps (PWA), served locally or remotely
  • Peripheral & machine communication — barcode readers, serial/USB devices, Arduino-style controllers
  • Remote provisioning, automatic updates & self-healing recovery, offline-first

Improve & maintain

Integrations & automation

Connecting existing services and automating repetitive or error-prone processes.

  • Integration between existing systems
  • Workflow & process automation
  • Email, notification & communication flows
  • Removing manual data transfers

AI integration

Practical AI in business workflows — with evaluation and human control where it matters.

  • AI assistants & LLM integration
  • Assistants grounded in a convergent profile of how your business works — available as a pilot
  • Continuity — the business's working knowledge & judgment carried in the profile, not in one person's head
  • Cost-efficient operation — full-time AI assistance at usage-level cost, a fraction of a hire — measured on this practice
  • Automated document & data processing
  • AI security & guardrails
  • Evaluated, human-reviewed delivery

Modernisation & maintenance

Restructuring, migrating or replacing ageing systems — and keeping what runs reliable.

  • Migration off WordPress & legacy platforms
  • Legacy refactoring, step by step
  • Automated upkeep & optimisation — one command instead of drift
  • Backups & tested recovery

Linux servers & VPS management

Reliable infrastructure for the systems you depend on — servers set up, secured, updated and monitored, with automated backups and tested recovery, maintained as an ongoing commitment.

  • Initial setup & hardening
  • Update & maintenance automation
  • Monitoring & alerting
  • Automated backups & tested recovery

Present & protect

Digital PR & web presence

Web production, management and social media integration — the public digital footprint produced and kept current.

  • Web production & content management
  • Social media integration
  • Consistent presentation across channels
  • Regular content updates

Digital assets — definition & protection

What the business owns online, defined and protected — accounts, domains, content, data and brand identity in the age of AI.

  • Digital asset inventory & definition
  • Access & account security
  • Protection of content, data & brand identity
  • AI-era risks — impersonation & unauthorised use

Not sure where this fits?

Describe the problem, not the solution. A conversation costs nothing; a wrong architecture costs everything.

Engineering practice

How DelfinFlow engineers software

Direct technical ownership — the engineer responsible for architecture and implementation stays responsible for the outcome. No sales layer, no account manager, no handoffs.

  1. 01

    Discover

    Requirements and constraints captured precisely — scope deliberately kept where direct ownership is an advantage.

  2. 02

    Architect

    Boundaries, interfaces and data flows decided before complexity gets expensive. Structure first, code second.

  3. 03

    Build & verify

    Production engineering with testing, monitoring and verified backups. No partial solutions — edge cases are handled, not deferred.

  4. 04

    Operate & evolve

    Maintenance, monitoring and support — systems that remain understandable to whoever maintains them later.

Built for direct ownership. Projects are deliberately kept within a scope where one accountable engineer is an advantage: architecture, implementation and technical decisions stay connected rather than passing through organisational layers. Requirements, decisions and verification are documented throughout — the handover is artifacts, not memory. Where a project needs additional specialist capacity, architecture and technical direction remain clearly defined while extra implementation capacity can be introduced.
