Stabilisation

Income · P2P lending platform

Investor frontend back on a release cycle

to clear the inherited backlog: 10 days
faster page load: ~18%
of cooperation, variable workload: 4 years

The situation

The investor-facing frontend of a P2P lending marketplace carried an inherited backlog, and release cycles kept breaking.

What we did

A senior React/TypeScript engineer joined the client's team, cleared the inherited backlog in ten days, restored a regular release cycle and stayed on as the frontend owner — with the workload scaled up and down as the roadmap required.

Team: 1 senior frontend engineer
Stack: ReactTypeScript

“Working with Bonsay Tech was a game-changer for us. Their team delivered a high-quality software solution on time and within budget. Their attention to detail and commitment to our project's success were outstanding.”

The situation

Senior engineers

The situation

An outdated loan and guarantee management system at a public-sector financial institution had to be replaced — without losing a single record.

What we did

Senior Java, React and architecture engineers worked inside the client's programme for two years, built the new system and migrated all data from the old one. Several of them later joined the client's own team.

Team: 10 senior engineers over two years
Stack: JavaReactSolution architecture

“The role of the Bonsay team in establishing a strong team of experts and executing the project was instrumental to the successful execution of our strategic project. We enjoyed working with the diverse and multinational team, delivering results on time and with the required quality.”

Customer service AI

Service business · anonymised

Every enquiry answered in under 5 seconds

direct bookings: +20%
operations hires avoided: 2
first reply: <5 s

AI & automation

The situation

Enquiries arrived around the clock and waited for staff to answer them, book a slot and send a payment link.

What we did

An AI agent now reads every enquiry, collects the missing details, books the slot and sends the payment link. Anything unusual goes to a person for approval, and every action is logged.

Sales AI

B2B sales team · anonymised

sales conversion: +17%

AI & automation

The situation

Managers could listen to only a handful of calls, so coaching was based on a random sample.

What we did

Every call is transcribed and scored against the team's own playbook, and each rep gets coaching notes the same day.

Knowledge AI

Operations team · anonymised

A knowledge base that updates itself

manual work on transcription and document updates: −70%

AI & automation

The situation

Company knowledge lived in documents and recordings nobody could search, and keeping them current took hours every week.

What we did

A private search over the company's documents and recordings answers questions with sources and updates itself when documents change.

Team extension

Askend and Wisercat · Estonia

Developers placed into client projects for years

not weeks — placements that last: Years

Senior engineers

The situation

Estonian software companies needed developers for client projects without growing permanent headcount.

What we did

Bonsay placed several developers into their client projects for the long term, handling replacement and scaling as projects changed.

“Bonsay Tech transformed our hiring process. Within weeks, we had access to great developers who seamlessly integrated into our team. Their professionalism and efficiency made a huge difference in meeting our hiring deadlines.”
