Software consulting & product engineering · Trixamid
End-to-end web & mobile engineering,
built for production.
We take a product from first architecture diagram to the deploy that carries real traffic — custom web platforms, mobile apps and cloud systems built to your exact requirements, then kept running.
One team, discovery through SLA

What we build
Three core disciplines, one delivery team. Most engagements combine at least two — a platform rarely ships without the infrastructure under it.
Mobile apps
iOS and Android from one codebase where it makes sense, native where the requirements demand it.
- Offline-first sync
- Push, biometrics, deep links
- Store submission handled
Cloud & DevOps
Infrastructure defined in code, pipelines that deploy without a maintenance window.
- Terraform / Pulumi IaC
- Kubernetes & serverless
- Observability and alerting
How a build runs
Five stages from signed scope to steady state. Select a stage to see what happens inside it and what lands in your hands at the end.
Working stack
Chosen per project against your team's ability to maintain it after handover — never because it is new.

Bring us the requirement, not a finished spec.
Send a brief in a few lines. You get a call with the engineers who would build it — architecture options, risks and a milestone plan, before any contract.
Services
Three core practices that ship together. Each one is scoped as a set of milestones with named deliverables — you always know what exists at the end of a payment.
01 / web
Full-stack web engineering
SaaS products, enterprise portals and the APIs behind them. We design the data model first, then build back ends that stay predictable when traffic multiplies — connection pooling, queues, caching layers and load tests that prove the numbers before launch day.

- Enterprise & partner portalsSAML · audit logs
- Public and internal APIsREST · GraphQL · gRPC
- High-concurrency back endsqueues · workers · caching
- Legacy rebuilds and migrationsstrangler pattern
02 / mobile
Mobile app development
Cross-platform when one codebase serves both stores, native when the app requires targeted performance. Offline-first is the default: field users keep working without signal and sync resolves conflicts when they reconnect.
- Flutter & React Native buildsiOS + Android
- Native Swift / Kotlin modulesdevice integration

- Crash and performance monitoringpost-launch
03 / cloud
Cloud architecture & DevOps
Infrastructure written as code and reviewed like application code. Deploys go out during business hours behind a canary, roll back automatically on error-rate regression, and leave an audit trail. Everything runs in your cloud account under your billing.

Included in every build
Not upsells. These ship with the work, and each one is something you can check yourself before you accept a milestone.
| Deliverable | What it means in practice | How you verify it |
|---|---|---|
| Automated testing | Unit, integration and end-to-end suites covering critical paths, running on every pull request. | CI run on your repo |
| Documentation | Architecture decision records, API reference, environment setup and runbooks for on-call. | docs/ in the repo |
| Security review | Dependency and secret scanning, authentication and access-control review, OWASP Top 10 pass before launch. | written findings |
| Production deployment | Pipelines, infrastructure as code, staging parity, rollback path and a rehearsed release. | live canary deploy |
| Handover | Repos, cloud accounts, domains and pipelines transferred to you, with a walkthrough for your team. | ownership transfer |
Need a second opinion on an existing build?
We audit architecture, security posture and delivery pipelines as a standalone engagement — findings and a prioritised remediation plan, no obligation to hire us for the fix.
Solutions by industry
Reference architectures we have built before, adapted to your operation rather than sold as a product. Each starts from the constraint that defines the domain.
FinTech platforms
Money movement where an incorrect balance is an incident. Ledgers are double-entry and immutable; every state change is reconstructable from the event log.
- Core ledger & payments
- Idempotent transaction handling, reconciliation jobs, provider failover.
- Onboarding & KYC
- Identity verification flows, sanctions screening, case review queues.
- Risk & controls
- Rules engine, full audit trail for compliance and examiners.
Typical first release: 14–20 weeks
HealthTech data platforms
Clinical data arrives in formats built decades apart. We normalise it, keep access defensible, and make it useful to clinicians and teams.
- Interoperability
- HL7 v2 and FHIR ingestion, terminology mapping, deduplicated patient records.
- Privacy engineering
- Field-level encryption, consent enforcement, break-glass access logging.
- Clinical interfaces
- Triage and monitoring views designed for speed of read, not visual density.
Typical first release: 12–18 weeks
Logistics & supply chain
Plans break the moment an exception occurs. The system has to re-plan continuously and keep teams informed without manual overhead.
- Routing & dispatch
- Constraint-based optimisation, live ETA recalculation, driver app with proof of delivery.
- Warehouse operations
- Scan-driven picking, stock accuracy checks, ERP and 3PL integrations.
- Control tower
- Exception-first dashboards with alerting on SLA breach risk.
Typical first release: 12–16 weeks
SaaS & operations portals
Custom software systems built for high reliability, granular permissioning, and zero-downtime scaling.
- Multi-tenant architecture
- Isolated tenant data, flexible billing setups, enterprise SSO integrations.
- Data ingestion & reporting
- High-throughput data ingestion, warehouse sync, and live operational analytics.
- Granular permissions
- Fine-grained RBAC, detailed audit trails, and automated compliance logging.
Typical first release: 10–14 weeks
Your domain isn't listed?
The architecture patterns transfer. Tell us the workflow, the volumes and the requirements, and we will map it to something we have shipped.
How we engineer
Code shipped to production is the only real metric.
Demos, decks and 90%-complete branches prove nothing. Trixamid is built around a single measure of progress: working software running in a production environment, under real load, owned by the client. Everything in our process exists to shorten the distance to that point and to keep it stable afterwards.
We work as a small senior team. The engineers who scope the system are the ones who build it, and they stay reachable after launch. There is no handover from a sales architect to an offshore delivery pod.
What we guarantee
We don't publish client quotes or star ratings. These commitments are written into the contract instead, where they can be enforced.
Zero vendor lock-in
No proprietary Trixamid framework, no licence you keep paying for. Open standards, mainstream frameworks, and infrastructure any competent team can pick up.
Full IP and repository ownership
Code lives in your organisation from the first commit, not ours. Cloud accounts, domains, registries and pipelines are yours throughout, not transferred at the end.
Production-grade security
Threat modelling at design time, dependency and secret scanning in CI, least-privilege access by default, and a documented OWASP Top 10 review before any public launch.
Milestone-based delivery
Fixed, dated milestones with defined acceptance criteria. If a date is at risk, you hear it in the weekly review with options — not on the day it slips.
Principles we build to
The decisions that repeat on every project, made once and applied consistently.
Architecture before abstraction
Boundaries are drawn around business capabilities, not technical layers. We add a service or a queue when load or ownership demands it, never to look modern on a diagram.
Boring technology wins
A Postgres table beats a new datastore for almost everything. We reserve novelty for the part of the system that is genuinely novel.
Readable beats clever
Code is written for the engineer who inherits it. Explicit flow, honest naming, comments where the reasoning isn't visible in the code.
Automate the release, not the review
Every deploy is scripted and repeatable. Every change is still read by a human before it merges.
Observability is a feature
Structured logs, traces and dashboards are part of the definition of done. A system you cannot see into is a system you cannot operate.
Plan for the handover
We write documentation as if we leave next month, because a project that only we can run is a liability we sold you.
Talk to the engineers, not an account manager.
The first call is technical. Bring your constraints, your existing stack and the deadline that matters.
Start a project
Tell us what needs to exist and when. We reply within one business day with either a scoping call slot or an honest note that it isn't our fit.
