Symentic Technologies

Services

Four things, done properly.

We would rather do a narrow set of things well than claim everything. Here is what we actually do, and the stack we do it in.

01

Product engineering

From an idea to a system with real users on it.

We work out what the thing actually needs to do, design the data model and architecture around it, then build and ship it. We stay on afterwards, because the first month in production teaches you more than the three before it.

  • Discovery and technical scoping
  • Architecture and data modelling
  • Build, test, launch
  • Iteration once real users arrive
02

Web & mobile apps

The interface, and everything behind it.

Web applications, iOS and Android from a single codebase, and the APIs they run on. We build for maintainability — clear structure, documented decisions, no clever tricks that only make sense to the person who wrote them.

  • Web apps (React, Next.js, Astro)
  • Mobile apps (Flutter — iOS + Android)
  • REST APIs and backends (NestJS, Node)
  • Postgres, Prisma, AWS
03

Systems integration

Making other people’s software behave.

Most projects fail at the seams: the payment gateway, the channel manager, the terminal in the corner of the shop. We have spent years on those seams — certifying against partner APIs, handling their retries and their bad data.

  • Payment gateways and PCI-compliant card handling
  • Channel managers and OTA distribution
  • EPOS and hardware integrations
  • Third-party API certification
04

Support & hosting

Someone answers when it breaks.

We run infrastructure for our own products, so we run yours the same way: monitored, backed up, and with a person who picks up. Deployments are automated and reversible.

  • AWS infrastructure and deployment pipelines
  • Monitoring, backups and rollback
  • Security patching and dependency upkeep
  • Ongoing development retainers

Working together

How an engagement runs.

Step 01

A conversation

You tell us the problem. We tell you if we are the right people — sometimes we are not, and we will say so.

Step 02

A written scope

What gets built, what it costs, how long it takes. Fixed scope or a retainer, whichever fits.

Step 03

Short cycles

Something you can click at the end of every cycle. No twelve-week silences.
