The platform serves as a first point of contact for health queries, helping users make informed decisions about when to seek professional medical care.

What makes this project particularly noteworthy isn’t just the product itself, but the speed at which it was conceived, developed, and launched. In an industry where development cycles typically span months, Sweesh.dev’s ability to deliver in less than a week demonstrates the transformative potential of their approach to software development.

The Challenge

Creating an AI-powered health assistant in just five days presented multiple significant challenges for the Sweesh.dev team. The Polish healthcare market, like many around the world, faces increasing pressure from limited access to medical professionals, long wait times for appointments, and a growing demand for immediate health information. Doktorek.com was conceived as a solution to bridge this gap, providing reliable health guidance when traditional healthcare resources aren’t immediately available.

The technical requirements were substantial. The platform needed to:

• Process natural language queries about health concerns in Polish
• Access and interpret a vast database of medical knowledge
• Provide accurate, helpful responses without making diagnoses
• Maintain user privacy and data security
• Offer an intuitive, accessible interface for users of all ages and technical abilities
• Support both free and premium subscription models

Beyond these functional requirements, the five-day timeline created extraordinary pressure. Traditional development approaches, with their lengthy planning phases and sequential workflows, simply wouldn’t work. The team needed to compress what would normally be months of work into less than a week without compromising on quality or reliability—particularly critical for a health-related application where accuracy could impact user wellbeing.

This challenge required rethinking conventional development processes and leveraging AI not just as the product’s feature but as a core component of the development process itself. It demanded a team with specialized expertise who could work in parallel, make decisions quickly, and implement solutions efficiently without the bureaucracy that often slows larger organizations.

The Development Process

The five-day development sprint for Doktorek.com was a masterclass in efficient project execution. Here’s how the Sweesh.dev team broke down this ambitious project into a manageable timeline:

Day 1: Concept Refinement and Architecture Planning

The first day focused on transforming the initial concept into a concrete development plan. Rather than spending weeks on requirements gathering and documentation, the team conducted an intensive four-hour workshop with the client to define:

• Core user journeys and primary use cases
• Essential features for the MVP (Minimum Viable Product)
• Technical architecture and AI model selection
• Data privacy requirements and compliance considerations

By the end of Day 1, the team had created a streamlined project blueprint, selected the technology stack, and established clear priorities. They chose a modern stack including Next.js for the frontend, Node.js for the backend, and integrated with specialized AI services for natural language processing in Polish.

A critical decision made on Day 1 was to implement a “parallel track” development approach, where different team members would simultaneously work on separate components rather than following a traditional sequential process. This approach required precise coordination but dramatically compressed the timeline.

Day 2: Core AI Integration and Backend Development

The second day saw rapid progress on two parallel tracks:

1. AI Integration: The team configured and fine-tuned the AI model to understand and respond to health-related queries in Polish. This involved:
   • Training the model with medical terminology and common health questions
   • Implementing guardrails to prevent the AI from making diagnoses or providing dangerous advice
   • Creating fallback mechanisms for queries outside the AI’s knowledge domain
2. Backend Development: Simultaneously, backend developers built the API infrastructure, database schema, and user authentication system. They implemented:
   • Secure user accounts and data storage
   • Session management for conversations
   • Credit-based system for the freemium business model

By the end of Day 2, the team had a functioning AI engine that could answer basic health queries and a backend system ready to support user accounts and conversations.

Day 3: Frontend Development and User Experience

The third day focused on creating an intuitive, accessible interface that would make the complex AI technology approachable for users of all ages and technical abilities. The team:

• Designed and implemented a clean, medical-themed UI with a focus on the chat interface
• Created responsive layouts that work seamlessly across desktop and mobile devices
• Implemented real-time conversation functionality with typing indicators and message history
• Built the registration, login, and subscription management flows

The design prioritized simplicity and trust-building elements, using medical-themed visuals and clear language to help users feel comfortable asking health questions.

Day 4: Integration, Testing, and Refinement

Day 4 was dedicated to bringing all components together and ensuring they worked flawlessly as a unified system:

• The team integrated the frontend, backend, and AI components
• They conducted extensive testing across different devices and browsers
• They implemented analytics to track user behavior and AI performance
• They refined the AI responses based on internal testing feedback

A particular focus was placed on edge cases and error handling to ensure the system remained robust under unexpected conditions. The team also implemented monitoring systems to track the AI’s performance and flag any potentially problematic responses for human review.

Day 5: Final Polishing and Launch

The final day focused on:

• Addressing any remaining bugs or issues identified during testing
• Optimizing performance for speed and reliability
• Implementing final security measures and conducting vulnerability assessments
• Preparing marketing materials and launch communications
• Deploying to production and monitoring initial user interactions

By the end of Day 5, Doktorek.com was live and accepting its first real users. The team remained on standby during the initial hours after launch to address any issues that might arise as real-world traffic began to flow through the system.

This compressed timeline was only possible because of the team’s specialized expertise, their AI-first approach to development, and their streamlined decision-making process. Traditional development methodologies would have spent the entire five days just on planning and initial setup.

AI Implementation

The AI implementation at the core of Doktorek.com represents one of the most impressive aspects of this rapid development project. Rather than building an AI system from scratch—which would have been impossible within the five-day timeframe—the Sweesh.dev team took a strategic approach to AI integration that balanced speed with quality.

The team selected a foundation model with strong multilingual capabilities and then extensively fine-tuned it specifically for Polish medical terminology and health-related conversations. This approach allowed them to leverage existing AI capabilities while customizing the system for the specific domain and language requirements of Doktorek.com.

A critical aspect of the AI implementation was ensuring the system understood its limitations. The team implemented sophisticated guardrails to prevent the AI from:

• Attempting to diagnose specific conditions
• Recommending prescription medications
• Providing definitive medical advice that should come from healthcare professionals

Instead, the system was designed to provide general health information, explain medical concepts, suggest when users should seek professional care, and help users understand their symptoms in context. These guardrails were implemented through a combination of prompt engineering, output filtering, and continuous monitoring.

The team also addressed the challenge of medical accuracy by connecting the AI to a curated database of reliable health information. Rather than allowing the AI to generate medical information based solely on its training data, the system was designed to retrieve and synthesize information from verified medical sources. This approach significantly improved the accuracy and reliability of responses.

Privacy and data security were paramount concerns given the sensitive nature of health-related conversations. The team implemented end-to-end encryption for all conversations and designed the system to minimize the storage of personally identifiable information. User queries are processed in a way that separates identity from the content of health questions, providing an additional layer of privacy protection.

Perhaps most impressively, the team implemented a continuous learning system that allows the AI to improve over time based on user interactions. The system flags uncertain responses for human review and incorporates feedback to enhance future performance. This approach ensures that Doktorek.com becomes more accurate and helpful with each user interaction, creating a virtuous cycle of improvement.

The AI implementation also included language processing specifically optimized for conversational Polish, including understanding of colloquial terms for symptoms and health conditions. This attention to linguistic nuance makes the system feel more natural and accessible to users who might not be familiar with formal medical terminology.
