Business context

Geniusee became instrumental in assisting a Fortune 500 company in enhancing and customizing the Celery open-source library. Facing stability issues in corporate products due to bugs, our customer sought a swift and reliable solution to address these challenges, as they were incurring substantial financial losses. By leveraging Celery's capabilities, Geniusee efficiently tailored the library to align with the specific needs of these companies, enabling them to achieve greater stability and cost-effective bug fixing, thereby enhancing the overall performance of their corporate software products.

Key challenges:

Handling complex, older systems, providing a deep understanding of numerous dependencies.
Reviving Legacy code, transforming outdated software into efficient and modern solutions.
Ensuring support for various versions of Python, both older ones like 3.7 and newer ones like 3.10.
Guarantee compatibility for different brokers and backends, such as RabbitMQ and Amazon SQS.
Completely broken integration tests.

Work Approach

Scrum

Geniusee embraced the Scrum approach, fostering a collaborative and iterative development process. Through regular sprints and stand-up meetings, we kept the Fortune 500 company actively involved, ensuring alignment with project goals and priorities. By adopting Scrum, our team accelerated the delivery of customized solutions, maximized adaptability, and ensured that the evolving needs of the company were addressed promptly and effectively.
Legacy code

Within this cooperation, Geniusee employed a meticulous approach to work with the legacy codebase. We conducted a comprehensive code analysis, identifying potential pitfalls and dependencies and ensuring a seamless integration of new technologies. Through their expertise in refactoring and modernization, Geniusee revitalized the legacy codebase, unlocking its full potential and transforming it into a future-proof and high-performing solution for our client.
Customer-Centric Focus

We prioritized understanding the unique business needs and objectives of the Fortune 500 company, tailoring their solutions to deliver maximum value and meet specific requirements. Regular communication and feedback loops ensured that the project remained aligned with the company's evolving goals, leading to a collaborative and successful partnership.
Outstaffing

We provided the Fortune 500 company with access to dedicated, skilled professionals who have seamlessly integrated into the development workflow. This approach allowed the company to scale its development resources based on project needs, optimizing efficiency and cost-effectiveness. Our outstaffing model ensured efficient resource allocation, enabling benefits from Geniusee expertise and technical capabilities.

Process

Our client sought data engineering specialists with a profound grasp of Python. As they had a clear and well-structured vision, our collaboration unfolded in several carefully orchestrated steps.

This phase involved detailed planning and conceptualization of individual software components. We worked closely to identify specific functionalities and requirements, breaking down the project into manageable pieces. Through iterative design and validation, Geniusee ensured that each component aligns with customer's standards and seamlessly integrates into the larger software ecosystem, fostering a successful and cohesive development journey.
We leveraged Celery's robust framework to orchestrate complex data processing tasks. By seamlessly integrating Celery into corporate products, we delivered scalable and efficient solutions that empower data-driven decision-making, ensuring the client maintains a competitive edge in their industry.
Delivering integration tests for the Celery library to a Fortune 500 company's suite of corporate tools involved a meticulous process. We meticulously designed test cases that simulate real-world interactions with the Celery-based system, validating task execution, asynchronous behavior, and result accuracy. Our comprehensive testing ensured smooth interoperability, minimizing risks and ensuring the flawless integration of Celery into the company's critical corporate tools.

Project Tech Stack

The project tech stack revolved around the powerful tool Python. The project's complexity was heightened by the need to support various Python versions, ranging from 3.7 to 3.10, despite the original code being written in Python 3.7. Geniusee leveraged Python innovations to build a robust and scalable solution, enabling seamless integration with existing systems and ensuring efficient development throughout the project lifecycle.

Features

Stamping API
By developing a Stamping API for the Celery-based system, we have provided a structured and accessible way for our client to interact with the system's capabilities. This API specifically enables developers to create, manage, and monitor task execution stamps within their corporate products. The Stamping API handles the automatic generation of unique identifiers for tasks, logs task progress, and tracks completion statuses. This ensures seamless integration with Celery, making it easier for in-house developers to efficiently utilize task queues, enhance workflow automation, and improve overall productivity.
Integration Tests
Since Celery is often used for asynchronous and distributed processing, integration tests are crucial to ensure that communication between our client's corporate application and Celery functions correctly. Initially, these integration tests were broken, leading to issues in task execution and system reliability. We stepped in to help fix these problems by thoroughly reviewing and updating the tests. Given the complexity that the system needs to work with different brokers and backends, we paid close attention to simulating real-world scenarios as closely as possible. This effort ensured that the integration between our client's corporate product and Celery is now robust and reliable.
