These are the tools Apoliums uses most, and the reason each one is on the list. Nothing here is a package deal — the choice follows what the system has to do, what your team can maintain, and how long it has to keep running.

Frontend
The part your customers judge you on. Rendered on the server where speed and search matter, interactive where the work happens.
React
The component model everything else is built around. Large hiring pool, long support horizon.
Next.js
App Router for server components, streaming and route-level caching — pages that arrive as HTML rather than as a loading spinner.
TypeScript
Types across the whole stack, so a renamed field breaks the build instead of a customer's screen.
Tailwind CSS
A token-driven design system in the markup. Consistent spacing and colour without a stylesheet nobody dares delete.
Backend
Where the business rules live. Chosen for the work: Node when the team is already in TypeScript, Python when the work is data or models.
Node.js
One language across client and server, and the same types shared between them.
Express
A thin, explicit HTTP layer for services that need routing and middleware without a framework's opinions.
Python
For data pipelines, model-adjacent work and anything that has to sit near a scientific library.
REST and GraphQL
REST by default with a documented error catalogue; GraphQL when many clients need different shapes of the same data.
Mobile
One codebase, both platforms, native where it has to be.
React Native
iOS and Android from a single codebase, with native modules written when a feature needs the platform directly.
Offline and sync
Queued writes and conflict handling designed in, because a phone's network is unreliable by default.
Secure device storage
Credentials in Keychain and Keystore, never in plain app storage.
Store releases
Signed builds, staged rollouts, and API versioning that keeps older installed versions working.
Databases
The decision that outlives every screen. Relational unless there is a reason, cached where reads are hot.
PostgreSQL
The default. Constraints, transactions and indexes doing the work the application should not have to repeat.
MongoDB
Where documents genuinely vary in shape and joins are not the access pattern.
Redis
Caching, rate limits, sessions and job queues — with invalidation planned rather than hoped for.
Vector storage
pgvector alongside the primary database, or a dedicated store when retrieval volume justifies it.
AI
Models are one component in a system. The engineering around them — retrieval, evaluation, cost control, fallback — is what makes them usable.
OpenAI and Anthropic
Provider choice made per task on cost, latency and output quality, behind an interface that lets either be swapped.
LangChain
Used where orchestration earns it, not as a default wrapper around a single API call.
RAG
Chunking, embedding and retrieval tuned against your own documents, with answers traceable to the source passage.
Evaluation
A test set and a scoring loop before launch, so a prompt or model change is measured rather than guessed at.
Cloud and delivery
The same steps for every environment, so releasing on a Friday is a non-event.
AWS
Compute, storage, managed databases and queues for systems with compliance, residency or scale requirements.
Vercel
For Next.js applications where edge delivery and preview deployments per branch matter more than infrastructure control.
Docker
Multi-stage images so development, staging and production run the same artefact.
CI/CD
Types, linting and tests on every push; migrations gated; rollback documented before the first deploy.
How we choose
Four rules that keep the list short.
- Boring beats novel
- We choose tools with long support horizons and enough engineers in the market to hire. A stack that is exciting now and unstaffable in three years is a cost we would be handing you.
- Fewer moving parts
- Every service, queue and third-party account is something to monitor, patch and pay for. We add one when the alternative is worse, not because a diagram looks better with it.
- Your accounts, your keys
- Cloud, repository, domains and vendor accounts belong to you from the first commit. Nothing we set up should depend on us still being involved.
- The stack follows the problem
- None of this is a package. If your team already runs Django or .NET and the work belongs there, we say so rather than proposing a rewrite you did not ask for.
