Product engineering
01From concept to something real in a user's hands. Web apps, APIs and the business flows underneath — built to grow, not just to demo.
- Web apps & SaaS
- API design
- 0-to-1 MVPs

Software engineering
Software engineered
to last and to adapt.
DynFoundry designs and builds software around each problem — architecture solid enough to run for years, flexible enough to scale as you grow.

Capabilities
Four kinds of work
Broad enough to own the outcome, narrow enough to do genuinely well.
Architecture & platform
02System design, data modelling and deployment infrastructure. Decisions made today that do not become next year's technical debt.
- Systems architecture
- Data modelling
- Infrastructure & CI/CD
Performance & reliability
03Root causes, not symptom patches. Measure, optimise, and set operating thresholds you can hold yourself to.
- Performance audits
- Observability & alerting
- Infrastructure cost reduction
Technical advisory
04Working alongside in-house teams: architecture reviews, technology direction, and raising the engineering bar across the group.
- Architecture review
- Technology selection
- Team mentoring
Pricing
Fixed prices for a fixed scope
These three packages cover most business website work. Each price is for the agreed scope in full — no hourly billing, no quiet extras.

How we work
Four stages, no surprises
Each stage ends in a concrete deliverable you can judge before committing to the next.
- 01
Discovery
Clarify the problem, the constraints, and what success means. Ends with scope and estimate in writing.
- 02
Blueprint
Architecture, data model and delivery plan. You see the whole shape before the first line of code.
- 03
Build
Two-week cycles, a working build at the end of each. No long silent stretches.
- 04
Operate
Handover with documentation, monitoring and a support window. The system is yours, not ours.

Edge-first should be the new default
Why most web applications in 2025 should start at the edge rather than a central origin.

Have a system that needs to be done right?
The first conversation is always free, and always ends with a concrete direction — even when that direction does not involve us.
