Custom software development, documented the way we engineer it.
A London software company for founders with an idea, teams that need a dedicated developer, and anyone holding an AI-generated MVP that stopped working once real users arrived. We also audit code other developers wrote. We build solutions. You grow your business.
Core stack
Specialized engineering
View all servicesSaaS Development
Multi-tenant platforms with subscriptions, roles and usage limits, built to survive growth.
DetailsWeb Application Development
Complex, data-heavy web applications where performance and correctness matter more than animation.
DetailsBackend & API Development
High-throughput, event-driven services, queues and integrations that hold under real load.
DetailsDedicated Development Teams
Senior engineers or a full squad embedded in your process, working as part of your team.
DetailsVibe Coding Rescue & AI-Code Takeover
Your AI-generated MVP works in the demo and breaks in production. We take it over and make it real software.
DetailsMVP Development
You have the idea and the market. We build the first version that answers whether people will pay for it.
DetailsTechnical Consulting Sessions
A senior engineer for a focused session on the decision you are stuck on. No retainer, no project.
DetailsCode Audit & Technical Due Diligence
An independent read on code someone else wrote, before you pay the final invoice or sign the acquisition.
DetailsFractional CTO & Technical Advisory
Ongoing senior oversight of the developers you already have, so you stop taking their word for it.
DetailsMulti-tenant WhatsApp automation platform
SaaS
Problem: The product needed to run automated WhatsApp conversations for many business tenants at once.
Engineering decision: Queue-level throttling could not express per-number Meta limits. A Redis token bucket keyed by tenant phone number let workers stay generic while throughput stayed compliant.
Engineered for reliability
Sheet 01 of 08
Discovery
We map the business problem, the users, the constraints and what success actually means. Output: a written scope you can challenge.
Sheet 02 of 08
Requirements & architecture
Data model, API contracts, infrastructure topology and the risky parts identified before code is written.
Sheet 03 of 08
UI / UX
Flows and screens for the paths that matter, built on a design system rather than one-off mockups.
Sheet 04 of 08
Development
Short iterations on a trunk-based Git workflow. Every change goes through pull request and code review.
Where our work has shipped
SaaS & product companies
Multi-tenant platforms, subscription billing, usage metering and the admin tooling that keeps support out of the database.
E-commerce & marketplaces
Storefront performance, catalogue scale, checkout reliability and migrations away from legacy platforms.
Logistics & operations
Dispatch, tracking, job state machines and reporting for teams replacing spreadsheets with real systems.
Fintech-adjacent products
Reconciliation, audit trails, idempotent payment flows and integrations that cannot silently lose a transaction.

Engagement models
Fixed-price project
Well-defined scope, agreed milestones, fixed budget. Best after a discovery phase.
Time & materials
Evolving scope with a monthly cap. You see the backlog and set priorities each sprint.
Monthly dedicated team
A stable squad reserved for you, billed monthly, scaled with 30 days' notice.
Long-term partnership
Ongoing product development, maintenance and on-call support under one agreement.

Two ways to start, both of them cheap.
Book a call and talk it through, or write the problem down and send it — whichever you would actually do today. Either way you get a reply from an engineer within one business day, and an honest answer about whether we are a fit.
Not ready for either? A $600 consulting session buys one straight answer with no obligation to hire us.
