FinTech Engineering Approach
Our FinTech Engineering Approach enables us to promptly design and implement new, efficient solutions for FinTech startups. We adopt proven practices and use different strategies depending on the stage of each startup.
FinTech Engineering Approach

Financial domain knowledge

To develop high-quality software without wasting time on miscommunication and reworking, we provide FinTech startups with software engineers that have a deep understanding of the financial domain. Together with the client’s team, we work out a training plan to help engineers understand the nuances of the client’s business.

Processes and workflows

In early-stage FinTech startups, Agile with short sprints and releases ASAP is mostly used. During quick discussions, the team plans sprints. Manual testing is satisfactory for QA. We help late-stage FinTech startups establish project management processes, deploy a pipeline, implement automated testing, and establish CICD.

Technologies and architecture

During the early stage, we help FinTech startups to rapidly build an MVP and release it. They receive feedback and can validate or improve their business model. In the later stages, we help FinTech companies to speed up development and pay down technical debt.

Team structuring

In the early stages, FinTech startups have small development teams that mostly consist of full-stack developers, each might work on any part of the system. As FinTech startups evolve and their teams grow, we help them split a single team into well-structured, cross-functional squads, establish effective coordination, assign responsibilities, and reduce the development cycle.

FinTech software product

As a result, our FinTech product meets clients’ needs and expectations, and maintenance and further development do not demand considerable effort. This leads to the success of the FinTech startup.

Their team is very efficient, every sprint that was planned, was completed on time – so it felt like fixed cost based contract although it wasn’t. They have really good resources – we had team of 6 (front-end developer, back-end developer, 2 QAs and Tech Architect and PM) – each and every one of them were skilled & senior. I personally had gone down to Kiev to meet Vasyl and the team and spent 2 days with them – Vasyl has formed very impressive management style where developer get to choose their own projects etc and very efficient I must say.

INSART has shown remarkable performance during the time we’ve been using their services. Although engaging them to support our current platform was not in our plans at the beginning, we have gradually come to regard them as our strategic partner whose involvement in our projects is mission-critical to their success. Not only have they been able to satisfy all our requirements, but they have also shown themselves as a collaborative, creative, and immensely talented team.
