Who we work with
For agencies
Frontend implementation, APIs, integrations, data workflows and repairs delivered in your or your client's repository. You own the client relationship; scope, confidentiality and handover are agreed in writing.
Agency deliveryFor companies
Fix a fragile application, replace a manual spreadsheet workflow, connect existing tools or build a bounded operational application.
Direct company projectsWhat we deliver
Web applications, APIs, data workflows and bounded integrations inside existing repositories.
Stabilise fragile codebases, refactor critical paths and replace brittle manual processes with tested software.
After delivery, bounded ongoing maintenance for systems ISW has agreed to support, with allowances and exclusions defined in writing.
How we deliver
01
Agree on requirements, deliverables and acceptance criteria before work starts.
02
Use the agreed repository, tools and communication process, whether yours or your client's.
03
Deliver the work with testing and error handling appropriate to the risk.
04
Provide documentation and a clear account of what was delivered so your team can continue.
This is the approach we recommend: from an agreed scope to a documented handover.
Selected systems
Business problem, technical intervention, delivered system.
Replacing fragmented publishing workflows with a controlled digital platform for a label and distro.
Delivered
CMS architecture, storefront, content modelling, server-side Sanity adapters, deployment pipeline, instrumentation, and handover. One source of truth for releases and distro listings.
Replacing inbox tabs, sticky notes and an unused PMS with one occupancy, messaging and guest-page surface for a small guesthouse.
Delivered
Staff open one Portuguese-first screen for today's occupancy, every room, arrivals, guest threads, and guest-page updates - instead of juggling inbox tabs, notes, and a PMS.
A front-desk copilot that answers only from approved SOP manuals - and refuses when the corpus does not support an answer.
Delivered
grounded answers with cited SOP source, refusal path, PII masking before orchestration, request receipts, SOP browser, and a system monitor.
Replacing spreadsheet-and-tribal-knowledge compliance with a walkable Digital Product Passport for steel.
Delivered
Operators review identity, materials, carbon, traceability, circularity, and compliance certificates for a steel batch in one six-pillar console - instead of chasing spreadsheets.
A lab-credible LIMS console so stakeholders can walk strain, QC and pipeline flows before any instrument is wired. All data is simulated.
Delivered
operator console, pipeline schema view, simulated strain and QC states. Explicitly not connected to live sequencers or production databases.
Game and R&D studio site for experiments, releases, and in-browser prototypes under one roof.
Delivered
A fast, maintainable home for studio work, playable demos, and R&D without heavy CMS overhead.
How we sell and deliver
Every quote states the deliverable, assumptions, exclusions, acceptance criteria and handover. New features and third-party costs stay separate from support plans.
