Motivation
The client needed a fast, accurate, and cost-effective platform for connecting users with local tradesmen. Their main pain points were high lead generation costs, low search relevance for user queries, and lack of trust between users and service providers. The goal was to implement a smart, NLP-powered search engine, a transparent reputation system, and integrated payments to create a reliable and engaging online services marketplace.
Main challenges
Challenge 01
High Lead Generation Costs
The customer needed a cost-effective alternative to SEO and PPC for attracting clients to the platform. We offered an online marketplace where tradesmen could gain visibility through organic search and reputation-based ranking instead of paid promotion.
#1
Challenge 02
Low Search Relevance and User Frustration
The existing search solutions couldn’t handle natural, complex queries, leading to irrelevant results. We decided to built a machine learning-powered search engine with NLP capabilities to understand user intent and deliver accurate matches.
#2
Challenge 03
Lack of Trust Between Users and gProviders
The customer needed a mechanism for building trust between service providers and clients. Our team implemented a transparent reputation system based on completed jobs and real user reviews, removing the need for tradesmen to pay for visibility.

Our approach
Rapid MVP Development with Ruby on Rails
We chose Ruby on Rails to quickly develop and deliver a Minimal Viable Product, using the framework's modularity to expand functionality over time.
Machine Learning-Powered Search Engine
Data extracted from websites was unstructured. We used a NoSQL database to store this data in a structured format, which allowed recruiters to search and evaluate candidates effectively.
Full-Cycle Development
Azati managed the entire development cycle, including project management, frontend and backend development, mobile apps, and infrastructure setup.
Community-Driven Reputation System
We enabled tradesmen to maintain profile pages with reviews and job ratings, fostering trust through completed work rather than paid promotion.
Loyalty and Referral Program
We implemented gamified mechanics like referral bonuses and early registration points to encourage adoption and reduce subscription costs for users.
