The chatbot had to handle standard customer service stuff—automated responses based on user inputs, collecting customer data through conversational flows, storing everything in our database, and knowing when to hand off to a live agent for more complex issues. Nothing groundbreaking, but it needed to work reliably and integrate cleanly with our existing systems. We needed developers who could understand our architecture and write code we wouldn't have to refactor later.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

They nailed it. The chatbot does exactly what it's supposed to do—handles the routine queries, captures the data properly, and routes to human agents when needed. The code was clean and well-documented. We were really happy with how well it integrated. The best part is we didn't run into those typical headaches where you have to go back and fix architecture missteps or integration blunders. They got the data flows right from the start.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

They had the standard setup, and it aligned with our ops, so we were happy with it. Slack for quick questions, Jira for tracking, and they were never against hopping on a call and digging deep. We had complete visibility into what they were doing, and they flagged anything that could put a stopper to our timelines. No surprises, which is what you want.

What did you find most impressive or unique about this company?

They were grandmasters of tech. We never had to explain a thing to them more than once. They got it right off the bat. We would be talking about our codebase specifics, and they would be in sync with us all the way through. Also, they didn't try to upsell us on features or trick us into extra work we didn't need. Kudos to everyone on their team!

Are there any areas for improvement or something Pynest could have done differently?

We could've done with a bit more edge cases covered by the quality control. We caught them all in our QA process anyway, so it's just a small thing to consider.

Describe the scope of work in detail. Please include a summary of key deliverables.

Pynest's project was to improve the client's inventory management system by combining different data sources, looking at stock levels, evaluating risks, and showing the results. The project was divided into four key stages:
Integration and Migration Module:
Objective: To integrate primary data sources and migrate data from Azure services to a new environment.
Activities: The team worked on setting up data pipelines to ensure seamless and consistent data flow. They utilized tools like Python, SQL, and Pyspark to extract, transform, and load (ETL) data into the new system. This stage ensured that all necessary data was accurately migrated and integrated.
Stock and Over-Stock Analysis Module:
Objective: To analyze and calculate stock levels, identifying stock and overstock situations.
Activities: The team developed algorithms and processes to evaluate inventory data and determine stock levels. This involved storing the analyzed data in an intermediate storage solution, such as Clickhouse, for further processing. The analysis helped in understanding current stock levels and identifying any overstocked items.
Risk Analysis Module:
Objective: To assess the risks associated with stock levels based on the analysis from the previous module.
Activities: This module uses stock data to look at possible risks related to inventory management. The team implemented risk assessment algorithms that forecasted future risks and identified potential issues. This stage provided critical insights into the areas of inventory that required attention to mitigate risks.
Visualization Module:
Objective: To visualize stock at risk and actual write-offs using various charts and diagrams.
Activities: The team developed a visualization dashboard that presented the analyzed data in a user-friendly format. They utilized tools like Datasphere, ObjectStorage, and visualization libraries in Python to create interactive and informative charts. This module helps stakeholders easily understand the data and make informed decisions regarding inventory management.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

The project resulted in several notable outcomes:

• Improved data integration and migration processes, leading to more reliable and timely data access.

This development includes improving the existing pipeline’s performance and making our UI as user-friendly as possible, as well as creating new services for our users so that we remain the best choice among other competitors. Since almost all parts of our application were written with Python, we hired Pynest developers to help us with continuous improvement. 

The Pynest developers advised us on the best solutions for implementing new services or optimizing existing ones, and they also enabled changes in code style and architecture in the project to make it more extensible and easier to test from the point of view of experienced Python developers.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

We have fully completed and tested the part of our pipeline that is responsible for processing user subscriptions. Overall performance of this pipeline has increased by more than 7 percent, and now we can handle an infinite number of user subscriptions. Additionally, the Pynest team created new internal UI tools for our managers to directly interact with these backend microservices; therefore, saving a lot of time for our managers. 

Our UI, with which users interact, has been improved as much as possible. In the end, we no longer need to worry about these microservices for a very long time, since all their parts are impeccably improved. How effective was workflow between your team and theirs? It was a pleasure to work with Pynest developers since all the developers had strong English/communicative skills. 

They are experts with Python and easily helped our developers to resolve bugs and implement new features.

The Pynest team implemented and refactored the codebase with high standards regarding code style, architecture, and performance. Additionally, the team left plentiful documentation inside our entire codebase itself and wrote documentation files for each microservice to describe how the particular microservice works and for what purposes it was created. 

They also left documentation for the whole pipeline of 8 microservices and external services with descriptions of how they communicate with each other, and what the input of this pipeline is, and what the output is for our users (after processing the user’s subscription). 

So, our developers can easily dig into the codebase and fully understand it through reading corresponding documentation files and comments inside the codebase. This is the best part of our pipeline right now in terms of the codebase, and our developers even use it as a standard in their own work.
