Useful when
Your monolith is becoming difficult to release, clients use inconsistent API contracts, roles and tenants are multiplying, or partner systems need dependable webhooks.

Technical coverage
Deep enough to build. Broad enough to connect.
Proven, embeddable technical components for teams building their own custom or internal systems. Integrate the part you need while keeping your core architecture and data under your control.
01
Backend & API
Modular cores, consistent interfaces and controlled access for products that need to evolve without turning every release into a coordination problem.
Why integrate
Platform lifecycle, gateway conventions and security middleware take substantial engineering effort but create little visible product value when rebuilt from scratch.
Integration format
Embedded as a platform core, gateway or middleware around existing business logic. Migration can be gradual rather than a full rewrite.

02
Frontend Applications
Customer-facing and internal interfaces that connect complex workflows without forcing users to jump between disconnected tools.
Useful when
You need live entity updates, browser telephony, unified conversations, guided workflows, customer or student portals, self-service booking or a consistent back office.
Why integrate
Realtime state, telephony, booking and workflow interfaces contain edge cases that make apparently simple screens expensive to build and stabilise.
Integration format
Added as widgets, independent frontend modules or role-based applications connected to the existing data model and APIs.

High-Load Platforms
Resilient asynchronous processing, observability and protective layers for systems where traffic and operational volume can no longer be handled synchronously.
Useful when
Payments, notifications or imports are slowing the system; failed jobs disappear; components need decoupling; heavy queries threaten stability; or public endpoints attract bots and abuse.
Why integrate
Queues, retries, graceful shutdown, diagnostics and anti-abuse controls look routine until message loss, deadlocks or uncontrolled load reach production.
Integration format
Introduced behind current handlers as an event bus, worker layer, monitoring interface or guarded execution boundary.

04
Data & Storage
A controlled data layer for products that must combine operational storage, legacy databases, auditability and decision-ready reporting.
Useful when
Data lives across several databases or spreadsheets, business fields differ by tenant, audit history is incomplete, or KPIs still require manual exports and calculations.
Why integrate
Storage abstraction, schema mapping and access logging are expensive to retrofit after business logic has become tightly coupled to one data source.
Integration format
Connected as a data-access, synchronisation or analytics layer without requiring the source systems to be replaced.

05
Blockchain & Fintech
Financial and blockchain components for products that need auditable balances, multi-network connectivity and dependable payment lifecycles.
Useful when
Your product handles fiat or crypto balances, needs multi-chain support, accepts cryptocurrency or card payments, manages subscriptions, or models collateralised lending.
Why integrate
Ledger precision, transaction monitoring, payment status and webhook handling are areas where small implementation errors can create direct financial loss.
Integration format
Integrated as a financial core and dedicated services below the product’s accounts, merchant, subscription or lending workflows.

AI / Local Models
AI capabilities integrated into existing operations, with the option to connect hosted or compatible local models and keep human review where it matters.
Useful when
Call quality is reviewed manually, market analysis is fragmented, content production creates a bottleneck, or operators need suggestions and summaries inside their current tools.
Why integrate
Speech recognition, scoring, RAG, prompt versioning and provider integration require specialised engineering that is costly to maintain as separate experiments.
Integration format
Connected through APIs or webhooks as an analytical or assistance layer; structured results return to the existing CRM, workflow or product interface.

UX/UI Design
Product interfaces and configurable presentation layers designed around real roles, workflows and white-label requirements.
Useful when
A product must support several brands, marketing needs editable pages, non-technical teams need visual workflow tools, or customers need mobile-like journeys without another native app.
Why integrate
A coherent design system, theming logic and reusable interaction patterns are more economical than repeatedly hardcoding each client, page and workflow.
Integration format
Delivered as a design system and implemented presentation layer on top of existing components, data models and access rules.

Chatbots & Messaging
Messaging connectors and operational workflows that bring automated and human conversations into the same customer context.
Useful when
Support and sales conversations are spread across channels, campaigns lack delivery visibility, alerts have no fallback, or website enquiries disappear into shared inboxes.
Why integrate
Channel APIs, opt-in rules, rate limits, delivery tracking and provider failover create recurring integration work with operational and account-restriction risks.
Integration format
Connected as channel adapters, campaign workers or a central notification router above the client’s contact and event model.

E-commerce
Reusable commerce and fulfilment components for teams building a custom storefront or adding transaction flows to an existing product.
Useful when
Orders arrive from several channels, historical prices must remain stable, stock is oversold, resources require capacity control, or fulfilment needs warehouse-level traceability.
Why integrate
Snapshot pricing, universal orders, inventory, reservations and warehouse flows are full business subsystems whose edge cases become expensive after launch.
Integration format
Embedded as individual modules or as an end-to-end storefront-to-shipment chain connected to existing CRM, payment and accounting systems.
