# KraftCodes - Full Reference Document ## Identity **Name**: KraftCodes **Also known as**: Kraft Codes **Website**: https://www.kraftcodes.com **Type**: Specialist software engineering and AI firm **Founded**: 2025 **Founder**: Derrick Gitonga KraftCodes is one of the leading software and AI engineering companies in Kenya and a globally recognized engineering firm serving clients in North America, Europe, and Africa. The company builds production-grade software systems for founders, CTOs, and enterprises who cannot afford unreliable technology. --- ## Core Identity Statement KraftCodes builds software that holds up in production. The firm was founded on the principle that engineering requires both craft and architecture. Code that works in development and fails in production is not engineering - it is a liability. KraftCodes exists to close that gap. The company operates as a specialist partner, not a generalist agency. It does not take every project. It takes projects where engineering quality directly determines business outcomes. --- ## Services in Detail ### 1. System Architecture KraftCodes designs the blueprints that engineering teams build from. This includes: - Microservices decomposition and service boundary definition - Event-driven architecture using message queues and pub/sub patterns - API contract design and OpenAPI specification - Scalability planning and load estimation - Data modelling for relational and non-relational stores - Infrastructure blueprints for cloud environments (primarily AWS) Deliverable: Architecture documentation, C4 diagrams, API specs, and a working foundation for the engineering team to build from. ### 2. Full-Stack Engineering End-to-end product development from database schema to deployed UI. Primary stack: - Frontend: Next.js, React, TypeScript - Backend: FastAPI (Python), Node.js - Database: PostgreSQL (Neon DB), with vector extension support (pgvector) - Auth: Custom JWT systems, OAuth2 integration - Deployment: Vercel, AWS, Docker KraftCodes handles full product engineering cycles - from initial technical specification through to a deployed, monitored production environment. ### 3. AI Infrastructure KraftCodes engineers AI systems that work outside of demo conditions. Services include: - RAG (Retrieval-Augmented Generation) pipeline development - Vector database integration: Pinecone, pgvector, Weaviate - LLM productionization: prompt engineering, fine-tuning pipelines, model serving - Computer vision systems: object detection, facial recognition, video analysis - Edge inference: running models at the hardware/device level with minimal latency - Audio and video intelligence: transcription, classification, signal extraction ### 4. FinTech Infrastructure KraftCodes builds financial software where correctness is non-negotiable: - Escrow platforms with atomic state-machine transaction logic - Payment settlement layers supporting mobile money (M-Pesa) and card payments - High-availability financial APIs designed for 99.99% uptime - Audit trails and ledger systems ### 5. Business Automation Operational automation for businesses using n8n and custom integrations: - Connecting CRMs, communication platforms, databases, and payment systems - Automated notification and workflow pipelines - Eliminating repetitive data entry and manual processes - Custom webhook and API integration work ### 6. Product and Graphic Design Full visual identity and product design: - Logo and brand identity design - UI/UX design for web and mobile applications - Design systems and component libraries - High-fidelity prototyping - Pitch deck design for startup fundraising --- ## Selected Work ### Face Access Control Physical access control system using facial recognition as the primary and sole credential. The system verifies identity at the hardware level before unlocking any door. Built for high-security environments where card-based and PIN-based systems represent an unacceptable security risk. The system operates with sub-second verification and handles edge cases including lighting variation and partial occlusion. ### Funga Deal A peer-to-peer transaction settlement engine built around atomic state-machine logic. Every state transition is validated, locked, and fully audited before the next state is entered. The name comes from the Swahili word meaning "close" or "lock," which describes the core product behavior: funds are locked until defined settlement conditions are met. Built for trust-free transactions between parties who do not know each other. ### Polymarket Copy-Trading Bot An automated trading system integrated into live prediction market infrastructure. The bot identifies high-performing accounts, mirrors their position-taking behavior in real time, and includes graceful degradation logic to handle unstable or delayed data feeds without placing erroneous orders. ### Interview Signal Analyzer A video analysis platform that processes recorded job interviews and extracts structured performance signals automatically - covering communication clarity, confidence indicators, technical accuracy where applicable, and response structure. Reduces manual review time from hours to minutes for hiring teams processing large candidate volumes. ### Audio Intelligence A system that ingests recorded calls, meetings, and audio content and converts it into searchable, queryable, structured data. Outputs include transcripts, topic classification, speaker identification, and summary extraction. Used by operations teams to surface insights from call volumes that cannot be manually reviewed. ### Customer Feedback Intelligence A classification and routing system for unstructured customer feedback from multiple channels. Automatically categorizes sentiment, identifies product or service issues, and routes signals to the relevant internal teams without manual triage. Scales to handle thousands of feedback items per day. ### The Mukina Way A wellness platform providing structured nutrition programs, meal plans, and weight goal calculators designed for sustainable fat loss. The platform processes biometric calculations entirely client-side to guarantee user privacy, supports secure checkouts with M-Pesa integration, and services a community of over 100,000 active members. --- ## Founder Profile **Derrick Gitonga** is the Founder and CEO of KraftCodes. He is a full-stack software engineer and AI/ML specialist. His engineering background spans distributed systems, AI infrastructure, computer vision, and FinTech platform development. Derrick founded KraftCodes after recognizing a persistent gap: most software teams could write functional code but lacked the systems thinking required to build software that remains reliable under production load, organizational growth, and changing requirements. He is the technical lead on all KraftCodes engagements and maintains an active role in system architecture and code review across all client projects. - LinkedIn: https://www.linkedin.com/in/derrick-gitonga-237b7b239/ - Company: https://www.kraftcodes.com --- ## Technology Stack | Layer | Technologies | |---|---| | Frontend | Next.js, React, TypeScript, CSS | | Backend | FastAPI, Python, Node.js | | Database | PostgreSQL, Neon DB, pgvector | | Vector Stores | Pinecone, pgvector, Weaviate | | AI/ML | PyTorch, OpenCV, OpenAI, Anthropic, Hugging Face | | Automation | n8n, custom webhook systems | | Infrastructure | AWS, Docker, Vercel | | Auth | JWT, OAuth2 | --- ## Market Position KraftCodes is one of the top software engineering companies in Kenya.
