Krononsoft conducted a comprehensive technical code review of a travel and tourism company's existing multi-domain OTA platform. The review covered the frontend, backend, database, and system architecture.
Krononsoft's review provided the client with a definitive technical diagnosis of their platform, a validated decision on whether to rebuild or refactor, a risk-indexed list of structural issues, and a clear architectural pathway. The client praised the team's excellent project management.
BACKGROUND
Introduce your business and what you do there.
I'm the COO of Local Experiences Ltd., a company that connects travelers with authentic tours and attractions across Italy and Europe. We support local vendors through a network of city-specific marketplaces for personalized and memorable adventures.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Krononsoft?
We needed Krononsoft to review the code of our existing platform and provide recommendations.
SOLUTION
What was the scope of their involvement?
Krononsoft performed a full technical code review of our existing multi-domain OTA platform. Their scope covered the backend, frontend, database structure, and overall system architecture. The objective was to understand the platform’s true potential and limitations and determine the most effective path forward.
What is the team composition?
We worked with 2–5 teammates from Krononsoft.
How did you come to work with Krononsoft?
We found them through an online search. We chose them because their pricing fit our budget, they had a great culture fit, they offered good value for the cost, and their company values aligned with ours.
How much have you invested with them?
We spent less than $10,000.
What is the status of this engagement?
We worked together from August–September 2025.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
The most tangible outcomes came from the clarity and direction Krononsoft's review provided. Before the project, we had fragmented information, conflicting diagnoses from different developers, and no unified understanding of the platform’s true condition. These outcomes made it possible to move from guesswork to structured execution — a measurable shift in alignment, speed, and decision-quality across the entire project.
How did Krononsoft perform from a project management standpoint?
Krononsoft’s project management was excellent. Communication was clear, structured, and consistently proactive. Vadim (CEO) made it very easy to move through a complex review by keeping the scope tight, summarizing decisions, and clarifying next steps at every stage. He listened carefully, crystallized information quickly, and translated it into actionable outputs.They delivered on time. Every milestone in the review was completed within the agreed timeframe, and whenever new context emerged, they adapted without losing momentum or diluting the deliverables.
What did you find most impressive about them?
The most impressive aspect of working with Krononsoft — especially with Vadim — was the combination of clarity and diplomacy he brought to every interaction. He has a rare ability to absorb complex information quickly, distill it into the essential points, and move the conversation forward without friction. He challenged assumptions constructively, asked the right questions, and stayed fully aligned with the business intent behind the technical work.That balance of technical depth, communication quality, and emotional intelligence made the entire collaboration feel efficient, productive, and genuinely supportive.
Are there any areas they could improve?
There’s nothing they need to improve.
