Widely-adopted, well-documented technology, so your system can be maintained by any competent team — including one that is not us.

Ownership: Source code and schema handed over
Lock-in: None — standard tooling throughout

In short

What technology does Redlitmus use?

Redlitmus builds with React, Next.js, TypeScript and Tailwind CSS on the frontend; Node.js, Python and PHP on the backend; PostgreSQL, Supabase and MySQL for data; AWS and Azure for infrastructure; REST APIs and webhooks for integration; and LLM APIs, RAG and vector search for AI features.

Frontend

Interfaces that stay fast on mid-range mobile hardware

React
Next.js
TypeScript
JavaScript
Tailwind CSS
HTML5
CSS3

Backend & data

Application logic, APIs and the systems of record

Node.js
Python
PHP
PostgreSQL
Supabase
MySQL
MongoDB
Neo4j
Redis

Cloud & delivery

Where it runs, and how it ships

AWS
Google Cloud
Docker
Vercel
Git

Integrations & AI

The services we connect business systems to. AI is one mark rather than a row of vendors because the model is chosen per project — including ones a client already runs.

Frontend

Interfaces that stay fast on mid-range mobile hardware.

React: Component-driven user interfaces
Next.js: Server rendering, routing and performance
TypeScript: Type safety across large codebases
Tailwind CSS: Consistent design system implementation
HTML5: Semantic, accessible markup
CSS3: Responsive layout and motion
JavaScript: Interaction and client logic

Backend

Application logic, APIs and background processing.

Node.js: APIs, real-time services and integrations
Python: AI workloads, data processing and automation
PHP: Existing platforms and CMS-based systems
REST APIs: Documented, versioned service interfaces
Webhooks: Event-driven system-to-system triggers
Job queues: Retries, scheduling and background work

Database

Relational data models designed for reporting from day one.

PostgreSQL: Primary relational database
Supabase: Postgres platform with auth, storage and row-level security
MySQL: Existing systems and LAMP-based platforms
Neo4j: Graph database for connected data and knowledge graphs
pgvector: Vector search for AI knowledge systems
Object storage: Documents, media and generated files

Cloud & Infrastructure

Deployment, delivery and monitoring.

AWS: Compute, storage and managed services
Azure: Enterprise cloud deployments
Edge CDN: Global static and image delivery
CI/CD pipelines: Automated build, test and deploy
Monitoring & logging: Uptime, errors and integration health

Integrations

The connective layer between your systems and channels.

REST APIs: Third-party and internal service integration
Webhooks: Signed, replayable event delivery
WhatsApp Business API: Messaging, templates and conversations
Payment APIs: Gateways, subscriptions and reconciliation
CRM APIs: Two-way sync with existing CRM platforms
Courier & logistics APIs: Shipping, labels and tracking

AI

Applied AI grounded in your own data.

AI APIs: Hosted large language model services
LLM integrations: Assistants and AI features inside applications
RAG: Retrieval-augmented generation over your content
Knowledge systems: Indexed, searchable internal knowledge
Embeddings & vector search: Semantic search and matching
AI automation: Classification, extraction and routing

These are the technologies we work with. We do not claim vendor certifications or partnerships we do not hold.

Engineering practice

How the Work Is Actually Run

The stack matters less than the discipline around it. These apply to every engagement regardless of size.

Documented APIs

Every system exposes a versioned, documented interface so the next integration is not a rebuild.

Environment separation

Development, staging and production kept separate, with credentials held in a secret manager.

Source control & review

All work version-controlled with peer review before it reaches production.

Monitoring from day one

Errors, uptime and integration failures alert a person rather than waiting for a complaint.

Performance budgets

Core Web Vitals measured during development, not diagnosed after launch.

Handover by default

Code, schema, deployment steps and training are delivered as part of the engagement.

Technology

Got an existing stack?We will work with it.

Extending, integrating with or gradually replacing an existing system is common work for us. Tell us what you run today and we will scope from there rather than proposing a rebuild by default.
