Samkelo Maswana Aspiring AI Engineer | Full-Stack Developer | Hackathon Enthusiast I'm a passionate and purpose-driven developer committed to building innovative tech solutions that create real-world impact. My journey spans across AI, web development, and mobile apps, with recent projects focusing on multilingual job agents for refugees, decentralized event planning platforms, and smart claim management systems. I thrive in collaborative, fast-paced environments like hackathons, where creativity meets execution. I’ve worked with cutting-edge technologies such as React Native, Flutter, Next.js, FastAPI, PostgreSQL, OpenAI APIs, and Azure services. My focus is not just on building software — it's on solving problems that matter. Whether it’s empowering underserved communities through AI or automating real-world systems, I aim to blend tech with purpose.

Qubic Smart Escrow is an AI-powered trustless escrow system built on the Qubic blockchain to solve fraud, misinformation, and payment disputes in influencer marketing. The current Web2 ecosystem is filled with fake engagement, bot-generated followers, and unreliable payment processes. Brands often lose money, and creators struggle with delayed or canceled payments. Qubic Smart Escrow eliminates these problems by combining artificial intelligence, an Oracle Agent, and Qubic’s zero-fee smart contract architecture. Brands deposit funds into a Qubic smart contract, influencers submit their content, and a Python-based AI engine analyzes the post for authenticity. The model performs engagement analysis, bot detection, velocity scoring, and audience geo-matching. A TypeScript Oracle validates the AI results and triggers the C++ smart contract to automatically release or refund funds. All of this happens within seconds, with no gas fees, no intermediaries, and full transparency. The project includes verified AI services, a complete QPI-compatible smart contract with five procedures, and a modern React dashboard for creators and brands. Extensive integration, unit, and end-to-end tests ensure stability and accuracy. This submission focuses entirely on Qubic Smart Escrow as a complete and functional product. A future expansion called QubicStream, a zero-fee creator streaming platform, will only be developed if Qubic invests further in scaling the ecosystem.

IBM-RevenueX is an advanced AI-powered revenue optimization and sales automation platform built entirely on the IBM watsonx ecosystem. It leverages watsonx.ai, watsonx Orchestrate, and IBM NLU to transform raw CRM and sales data into deep, actionable insights that help businesses increase revenue, close deals faster, and reduce operational load. Designed for speed, scalability, and real-world business impact, IBM-RevenueX turns ordinary data into executive-level intelligence within seconds. Users can upload a simple CSV dataset, after which the system instantly analyzes every lead and performs lead scoring, conversion likelihood prediction, revenue forecasting, engagement analysis, and sentiment extraction. The system generates personalized follow-up messages, identifies upsell opportunities, and highlights the highest-value leads. All insights are beautifully presented in an intuitive React frontend, while the Node.js backend manages AI workflows, data handling, and IBM service communication. IBM-RevenueX functions like a full-time digital sales analyst and automation specialist, working around the clock. It reduces manual workload, empowers sales teams with predictive insights, and ensures every lead is followed up with at the right time using optimized messaging. With watsonx Orchestrate, the platform can automatically trigger CRM tasks, schedule follow-up actions, and even push notifications or automated workflows directly into business tools. An optional voice briefing mode uses IBM Speech services to summarize the day’s top opportunities, giving executives a hands-free, fast way to check revenue potential. This project shows how modern enterprises can deploy AI agents that not only assist—but actively operate—within key business processes. Built in just a few days, IBM-RevenueX demonstrates the true speed and power of building with IBM’s next-generation AI stack to deliver measurable revenue growth and operational efficiency.

ThinQ-Arc (ArcBot AI) is an intelligent conversational payment system that allows users to send, receive, store, and schedule USDC payments using simple chat or voice commands. It enables fast, low-cost financial transactions without requiring traditional banking apps, making digital payments accessible to busy users, small businesses, and communities with limited banking infrastructure. The system integrates with the Arc blockchain to process transactions securely and transparently. It features identity verification, confirmation prompts, spending limits, and AI-powered fraud detection to ensure every transfer is intentional and safe. ThinQ-Arc also supports recurring payments, cross-border remittances across African regions, and provides memory-based insights to help users track and repeat transactions quickly. By combining voice AI, blockchain security, and automated financial workflows, ThinQ-Arc makes sending money as easy as sending a message — simple, reliable, and always available.

📊 Understanding the Challenge Challenge A: Running Al Models on Qubic Nodes. Qubic nodes are not traditional compute environments like Docker or VM runners. They're designed for: - Deterministic compute (verifiable) - Time-based execution (ticks) - Cryptoeconomic security via Corol Protocol ### 2. Problem: . **Running non-deterministic Al models (like LLaMA) is**: - Heavy on resources (RAM, GPU) - Probabilistic in nature - Difficult to verify on-chain or across nodes This project is a decentralized microtasks platform where users can submit small tasks, such as summarization or classification, and have them processed by Al models like Llama 3 running on decentralized compute (Qubic nodes with Groq). Smart contracts manage task submission, escrow, and payments to node operators. Corol Protocol ensures consensus and trust in result verification.*
