System Architecture
The Pyjam app is developed as a centralized solution that facilitates interaction among all users (clients and freelancers) through a single platform. The system architecture is built on a client-server model, where the web interface or mobile app acts as the client, and the server processes requests, manages data, and coordinates interactions [9].
Key components of the system include:
- Frontend, developed using Angular, provides a dynamic and adaptive user interface.
- Backend, implemented using PHP and NestJS, ensures the application logic and API interfaces for interaction with the frontend.
- Database, managed using MySQL, stores all information about users, orders, transactions, and briefs.
- Session management system, including user authentication and authorization, implemented through JWT (JSON Web Tokens) and OAuth 2.0 to secure user sessions.
Technologies Used
To implement the smart contract mechanism for secure transactions and the briefing system, the Pyjam app uses a range of advanced technological solutions:
- Smart contracts: The app incorporates an automatic processing system for contractual relationships. This system uses server scripts and a database to track the status of contracts, compliance conditions, and transactions. Implementation is carried out through developed APIs that allow automatic changes to contract statuses in accordance with the fulfillment of conditions [1].
- Briefing system: Uses interactive forms with pre-filled answers, developed in collaboration with performers. This simplifies the task creation process and reduces the time for preparing specifications. Briefs are compiled and processed through a user interface, which connects to the server via a RESTful API to save and process data.
- Data processing and integration: All system components are closely integrated using REST APIs, ensuring reliable data exchange and state synchronization between the client and server. Data processing automation allows efficient management of user requests and operations on the platform.
This architecture and technological solutions enable the Pyjam app to provide a high level of performance, scalability, and security, making it a convenient tool for freelance platforms. A significant feature of the system is its ability to adapt to various client requirements and changes in the workflow, which is critical for the dynamically developing freelance service market.
Smart Contract Mechanism and Secure Transactions
Definition and role of smart contracts and secure transactions in Pyjam
In the context of the Pyjam application, a smart contract is a digital agreement, fixed in the system, which automatically manages the conditions of the contract between the client and the performer. This agreement is formalized in the form of a technical assignment (technical specification), which accurately describes all aspects of the upcoming work, including scope, deadlines, and quality criteria. The smart contract in Pyjam also includes mechanisms for reserving payment and subsequent payment, ensuring that both parties fulfill the agreements.
Components of the Smart Contract
- Approved technical assignment in digital form: Before starting work, the performer and client agree on the technical assignment, which is then fixed in the system. This technical assignment activates the smart contract, making it a "living" document that serves as the basis for all further operations.
- Reserved funds: After the technical assignment is approved by the client and the work is accepted by the performer, the funds necessary for payment are blocked in the system. These funds remain in reserve until the performer completes the assignment and confirms its execution, after which the system automatically transfers the money to the performer.
- Payment guarantee for the performer and work completion for the client: The smart contract guarantees that the performer will receive full payment immediately after the client confirms the compliance of the completed work with the approved technical specification. On the other hand, the client is protected from poor quality work or non-completion of the assignment, as the funds are transferred to the performer only after the work is approved.
Process of Working with the Smart Contract
- Creating a technical assignment: The client forms a technical assignment using the briefing system, which offers him options for answers to typical questions to compose the most complete and accurate description of the task.
- Approval of the technical assignment and commencement of work: After the technical assignment is formed, it is sent to the performer for review and approval. The performer can accept the technical assignment or propose changes. After approval, both parties sign the smart contract, and the client transfers the money into reserve.
- Completion of work and payment of funds: Upon completion of the work, the performer sends the result to the client for verification. If the work meets the approved technical assignment, the client confirms this in the system, and the reserved funds are automatically transferred to the performer.
This smart contract mechanism ensures a high degree of reliability and transparency in the interaction between platform participants. It minimizes the risks associated with non-fulfillment of agreements and provides both parties with clear legal and financial guarantees.
Advantages of the Smart Contract System in Pyjam
- Confidence in the transaction: Clients can be confident that their investments are protected, as payment occurs only after the completed work is approved, meeting all the conditions of the technical assignment.
- Guarantee for the performer: Performers gain confidence that they will receive their payment as soon as the work is approved, without delays and additional checks.
- Efficiency of processes: Automation of the smart contract signing process and transactions reduces the time and effort spent on administration and project management, allowing participants to focus on the quality of work.
- Transparency: All work conditions are clearly fixed in the digital technical assignment, available for viewing and verification by both parties at any time, which eliminates possible disputes or misunderstandings [6] (fig. 1).

Briefing System
Development of the Briefing System
The briefing system in the Pyjam application was developed with the aim of simplifying and standardizing the process of creating technical assignments (technical specifications) for orders. This tool allows clients to clearly and accurately formulate their project requirements, minimizing the possibility of misunderstandings and errors in their interpretation by performers.
Structure of Briefs
Briefs are composed of a series of predefined questions, each addressing a key aspect of the task. The questions are designed to cover all potential requirements and preferences of the client, including deadlines, budget, style, technical parameters, and other important details. Answers to the questions are provided in the form of multiple-choice options, which eliminates ambiguity and simplifies the process of formulating a technical assignment.
Dynamic Adaptation of Briefs
One of the key features of the briefing system is its dynamic adaptation to the specific type of task. For example, if the client chooses to create a video, the system automatically suggests questions specific to video production, such as video duration, preferred color schemes, and the need to create a script. If the client does not have a ready-made script, the system will suggest moving to the scriptwriting section before finalizing the video order.
Interaction between Users

he interaction process in the briefing system begins with the client, who selects the required type of service and answers a series of questions. The completed brief is then sent to potential performers, who can review the project details and offer their services. Performers have the opportunity to request clarifications or propose changes to the technical assignment if necessary to precisely match their capabilities and resources. Such interaction ensures that both parties fully understand the terms of cooperation before starting work [7] (fig. 2).
Generation of Technical Assignment
The final product of the briefing system is a detailed technical assignment, which is automatically generated based on the client's responses. This technical assignment becomes part of the smart contract, providing the legal and operational basis for the execution of the work. The documentation of the technical assignment includes all technical specifications and requirements of the client, ensuring that performers have a full understanding of the task and expected results.
Thus, the briefing system in the Pyjam application not only simplifies the process of creating a technical assignment but also increases its accuracy and compliance with the client's expectations. This system is a key element in ensuring effective and fair operation of the freelance platform, fostering reliable and fruitful cooperation among all participants in the process [5].
