Extend Your Website With Custom Functionality and Integrations

Lex & Tech Studio develops focused web microservices, APIs and integrations that add new capabilities to existing websites and digital systems. Whether you need to connect business tools, process documents, add AI functionality, integrate a CRM or build a custom backend service, we create targeted solutions around the specific problem you need to solve.

You do not need to rebuild your entire website to add one important capability.

Problems & Use Cases

Add What Your Existing Website Is Missing

Many websites work perfectly well for their original purpose but eventually need functionality they were never designed to provide.

Instead of replacing the entire system, a focused integration or microservice can often add the required capability while preserving the existing website.

CRM Integration

Document Processing

AI Features

Third-Party API Integration

Send website enquiries, contact information or other business data directly into your CRM instead of copying it manually.

Allow users to upload documents that can be extracted, classified, validated or routed through a dedicated processing workflow.

Add controlled AI-assisted functionality to an existing website or internal platform for specific tasks such as information processing, classification or knowledge access.

Connect your website with external services such as booking platforms, payment systems, business software or specialized data providers.

Custom Forms & Workflows

Authentication & User Areas

Database Functionality

System-to-System Automation

Build advanced forms that validate information, trigger processes, store data or communicate with other systems.

Add secure user accounts, role-based access or protected client areas where appropriate.

Store, retrieve and manage structured business information through dedicated backend services.

Enable different applications to exchange information automatically instead of relying on manual transfer.

If you can clearly describe what you want your website to do, we can determine whether a microservice, API integration or another technical approach is appropriate.

What We Build

Focused Technical Solutions for Specific Business Needs

A microservice is simply a focused software component designed to perform a particular function. It can operate behind an existing website or application without requiring the entire platform to be rebuilt.

Business Integrations

Develop secure interfaces that allow websites, applications and business systems to exchange information.

Build backend services that process documents or structured information.

Add narrowly defined AI capabilities to an existing website or application.

Connect your existing website to the tools your business already uses.

Typical uses:

  • website-to-CRM connections

  • mobile/web application backends

  • data access

  • third-party integrations

Typical uses:

  • PDF/text extraction

  • OCR

  • data validation

  • classification

  • structured data generation

  • file-processing workflows

Typical uses:

  • content classification

  • information extraction

  • internal search

  • text summarization

  • document analysis support

  • workflow assistance

Examples:

  • CRM

  • email systems

  • databases

  • payment services

  • automation platforms

  • booking tools

  • external APIs

AI components are introduced only where they provide clear practical value and can be implemented with appropriate controls.

Depending on the project, solutions may use .NET, Python, REST APIs, databases, Docker or other appropriate technologies. The technology is selected according to the functional requirements rather than imposed in advance.

Our Approach

Integrate Without Creating New Complexity

Minimal disruption

Clear responsibilities

Reliable integration

Maintainability

Add functionality without unnecessarily replacing systems that are already working.

Each service should have a defined purpose rather than becoming an oversized system that tries to do everything.

Data exchange, authentication, error handling and external dependencies are considered from the beginning.

The solution should be understandable, supportable and capable of evolving when business requirements change.

Adding functionality to an existing system requires more than writing code. The new component must work reliably with the website, external services, data flows and existing business processes.

Our approach focuses on understanding the existing environment before deciding how the new functionality should be introduced.

Four principles

Some projects may require access to an existing codebase, API documentation, hosting environment or third-party platform. Technical feasibility can only be confirmed after reviewing the relevant system.

Project Assessment

Tell Us What Your Existing System Needs to Do

Recommended Entry Service

Technical Integration Assessment

You do not need to know whether the solution should be an API, microservice, integration or custom backend component. Start by describing your existing website or application, the functionality you want to add and the systems that need to connect. We will assess the technical options and recommend the most appropriate approach.

A focused review of the existing environment and the functionality you want to introduce.

It can include:

  • current website or application architecture;

  • required functionality;

  • third-party systems involved;

  • available APIs;

  • data requirements;

  • authentication/security considerations;

  • integration constraints;

  • recommended technical approach;

  • implementation scope.

The scope of the assessment depends on the complexity of the existing system and the proposed integration.

No architecture document required. Start by explaining what the current system does and what you want it to do next.

Frequently asked questions

What is a web microservice?

A web microservice is a focused software component designed to perform a specific function, such as processing documents, connecting to another system or providing an API. It can often be added to an existing website without rebuilding the entire platform.

Can you connect my website to a CRM?

Yes, where the CRM provides appropriate API or integration capabilities. The exact implementation depends on the platform and the data that needs to be exchanged.

Do I need a microservice?

Not necessarily. A microservice is one possible technical approach. Depending on the problem, a direct API integration, conventional backend functionality or workflow automation may be simpler and more appropriate.

Can you add AI functionality to an existing website?

Yes. AI functionality can be added through a dedicated backend service or API when there is a clearly defined use case, such as document processing, classification, information extraction or internal knowledge access.

Can you integrate with an existing website built by another developer?

Potentially, yes. The existing website first needs to be reviewed to understand its technology, available access, hosting environment and integration possibilities.

Can you process uploaded documents?

Yes. A document-processing service can potentially handle upload, OCR, text extraction, classification, data extraction and routing depending on the document types and project requirements.

Can you build an API from scratch?

Yes. Custom APIs can be designed for applications, websites or internal systems when a dedicated interface is required.

How does a project begin?

The project begins with a review of the business requirement and existing technical environment. We then determine the appropriate architecture and define the implementation scope.
