From interface to API: the role of an Eximee low‑code developer in banking systems

When I first started working with the Eximee platform more than six years ago, my job was mostly about designing forms in a separate application with no friendly UI. There were no advanced JavaScript scripts, no BPMN processes, no data model, and no modern browser‑based environment like the one we use today. Even the simplest validator had to be added to the backend developers’ backlog. Over the years, the platform has gone through a massive evolution – and I’ve grown along with it.

Today, I’m the Team Leader of my low‑code team, which builds fully fledged business applications in the modern Eximee Designer. With this article, I want to dispel the myth that low-code is just a simple tool for creating landing pages, something that cuts you off from “real” programming and doesn’t require technical skills.

Business and technology requirements in the banking sector are so particular that nothing can be “just clicked together” without deeper thought. Today’s digital transformation in finance demands a level of speed that traditional development can’t always keep up with. Regulatory changes, advanced validations, and a strong focus on good UX mean that writing everything from scratch is more and more often giving way to more efficient approaches.

From a team leader’s perspective, I see every day how much this has reshaped the role of a low‑code developer. It stopped being “putting blocks together” a long time ago – now it’s engineering work that requires architectural thinking, system integration, and solving real technological challenges.

In short:

  • What does the role of an Eximee low‑code developer look like in practice? It’s about building multi‑layered, enterprise‑grade banking applications. The job involves designing interfaces (UX/UI) and modelling advanced, executable business processes using the BPMN 2.0 standard.
  • Why does it require interdisciplinary competences? Because the role seamlessly combines front‑end architecture (meeting WCAG and responsive design standards), process analysis, and software engineering, including writing dedicated business logic and JavaScript scripts.
  • How does it redefine work on banking system architecture? It replaces repetitive, low‑level coding from scratch with development at a higher level of abstraction. This accelerates time‑to‑market and shifts the focus toward secure integrations (REST API/JSON, SOAP/XML) with the bank’s external systems.

Why is low-code in banking truly “High Technology”? 

In Eximee, we don’t build generic templates or simple landing pages. Our platform automates advanced, omnichannel, enterprise‑grade processes for major financial institutions. The solutions our team delivers serve millions of users while meeting strict requirements for security, auditing, and accessibility (WCAG).

The role of a low‑code developer is that of both a business process architect and a creator of user experiences (UX). Instead of spending long hours writing repetitive, foundational code from scratch, an Eximee low‑code developer uses a powerful visual environment to deliver real business value – often up to several times faster. This isn’t avoiding programming; it’s programming at a higher level of abstraction.

Rather than getting lost in the complexities of low‑level front‑end frameworks, engineers in this role focus on business logic, optimizing data flow, and shaping the architecture of the entire application ecosystem.

What does this role actually involve? The everyday work of an Eximee low‑code developer 

Working with Eximee isn’t about using a simple editor – it’s about managing a full, multi‑layered business application. The role of a low‑code developer blends skills across front‑end, back‑end, and system analysis.

Today’s capabilities of Eximee are the result of years of continuous architectural refinement. I asked Monika Wachowska, who has been part of our team for a decade, about the biggest breakthrough in the platform’s history. What transformed Eximee from a basic form builder into a fully-fledged engineering environment?

When I started 10 years ago, Eximee was mainly used to assemble static forms, and any more complex validation or logic required involvement from developers. The biggest breakthrough came with the introduction of an advanced BPMN process engine in Designer, along with full support for JavaScript programming.

At some point, Eximee Designer evolved from a tool for ‘clicking fields together’ into a complete environment where we design entire business applications – from complex interfaces (UX/UI), through business logic, all the way to direct integrations with banking APIs. Today, we’re no longer limited by templates – we define the architecture and the flow of data ourselves.

Main responsibilities of an Eximee low‑code team

Designing an advanced visual layer (front‑end and UX/UI)

A low‑code developer is responsible for delivering a flawless interface (UI) for key banking processes, such as social security forms, account applications, loans, or business registration.

The foundation is a powerful drag‑and‑drop visual editor that allows developers to style elements in detail and configure component properties and behavior.

Every element must work within a fully responsive design (RWD) and meet digital accessibility standards (WCAG). A low‑code developer builds the interface using reusable building blocks, ensuring consistency with the application’s front‑end architecture (design system) while combining it with custom solutions where needed.

Business process modelling (BPMN)

This is the logical layer that drives the entire application. A low‑code developer maps and optimizes the paths taken by a customer or an employee of a financial institution.

We use the BPMN 2.0 notation standard. Working with BPMN at an enterprise scale requires deep understanding of process states, business flow, and error‑handling mechanisms. For us, the model isn’t just an analytical “diagram” – instead, it’s a living, executable piece of logic that powers the workflow engine.

Implementing business logic and scripts 

Where standard visual configuration ends, pure engineering begins. Low‑code developers regularly write dedicated scripts (primarily in JavaScript). These scripts handle dynamic validation of complex input data, advanced calculation rules, element visibility management, and transformation of data structures exchanged between the screen and the server.

System integrations and data operations

A banking application doesn’t exist in isolation. A large part of the low‑code developer’s role is connecting processes with the bank’s technology ecosystem. We integrate processes with external databases, systems, services, and identity providers through APIs. This requires knowledge of system communication standards (REST API/JSON, SOAP/XML). A low‑code developer configures data mappings, manages authorization, and ensures that, for example, the system can instantly and securely verify a customer.

Low‑code developer – a next‑generation specialist 

From the outside, someone might assume that working with a low‑code platform distances an engineer from “real IT,” but my experience at Consdata proves the exact opposite. An Eximee low‑code developer is a next‑generation specialist with a uniquely broad perspective. They understand integration mechanisms, know the architecture of financial systems, can implement custom logic in JavaScript, and at the same time bring business‑oriented empathy to designing BPMN processes and UX.

In this role, we move away from dry coding and repetitive line‑by‑line development. Instead, we focus entirely on the essence of engineering: solving real, complex business problems and delivering working systems that immediately bring value to the organization and end users.

FAQ: Working as an Eximee low‑code developer 

Do I need to know frameworks like React or Angular for this role?

No, knowing front‑end frameworks (React, Angular, Vue) is not required. The architecture of the Eximee platform frees engineers from writing low‑level visual code. What we do expect is a solid understanding of pure JavaScript (ES6+). It’s used to write dedicated scripts, implement custom validation logic, and transform data between the interface and the server.

What does the onboarding process look like for a new team member?

Every new employee is supported by a dedicated mentor who follows a structured onboarding plan and later helps integrate them into the sprint and assign appropriate tasks. We also provide our own online training materials. New team members complete practical exercises that prepare them for real project work.

Who is the low‑code developer role best suited for?

It’s an ideal path for people who value architectural thinking more than working within a narrow slice of code. The role combines development skills (JavaScript, API integrations), analytical skills (BPMN modelling), and design skills (UX). It’s a great fit for specialists who want to solve real business problems in enterprise systems rather than spend time writing repetitive boilerplate code.

Does lack of experience in the banking sector disqualify a candidate?

Absolutely not. What matters most are strong engineering fundamentals, analytical thinking, and willingness to learn. The ins and outs of financial processes, including strict security, auditing, and regulatory requirements, are taught during project work inside the organization.
