Reliable Web Development Partner That Delivered What They Promised

Daan Visser / IT Director | Sep 29, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

It has made a real difference to how our team works day to day. We would definitely work with them again.

Project summary

We hired Leszynski Group, Inc. to rebuild a slow, outdated web app and move it to a new framework. Their team handled planning, development and QA, with our product owner signing off each milestone. The project took roughly 2 months from kickoff to launch.

Great team to work with — professional, responsive and reliable

Joanne Tan / Marketing Director | Sep 19, 2026

Our experience with Leszynski Group, Inc. was really positive from start to finish. They shared working builds regularly, so we could test early and give feedback before things were locked in. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

The result looks great and performs well, and our internal team found it easy to take over. Happy to recommend them.

Professional team that made a complex project feel manageable

Megan Bennett / Director | Aug 13, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We are already seeing better numbers than before the project. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with Leszynski Group, Inc. to add an AI chatbot to our support site that answers questions from our help docs. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 2 months.

They listened, asked the right questions, and delivered

Lucy Evans / Director of IT | May 19, 2026

The project went well overall. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The IoT Development work has already made a noticeable difference — tasks that used to take hours now take minutes. There were some early misunderstandings on requirements that took a few rounds to sort out. We are already discussing the next phase with them.

Capable IT Managed Services team — happy with the end result

Hui Min Chua / Head of Product | May 15, 2026

The final product works well for us, although the process could have been smoother. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Feedback from our customers has been very positive so far. Their team changed one developer midway, which slowed things down for a couple of weeks. Happy to recommend them.

Quality work, a little slower than we planned

Brandon Johnson / Head of Product | May 07, 2026

The final product works well for us, although the process could have been smoother. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We launched on schedule and have not had any major issues since. Documentation at handover was a bit thin and we had to ask for more detail. I would recommend Leszynski Group, Inc. to anyone looking for a dependable IT Managed Services partner.
