Full-Stack Software Engineer | 5+ years shipping production systems I'm a full-stack software engineer with 5+ years building impactful, user-focused products across Fintech, Education, IoT, Web3, Sports, Dev Tools, and Health. I pair strong backend engineering with solid frontend craft to ship systems that are scalable, observable, and reliable in the hands of real users, not just demos. I'm now extending that foundation into Agentic AI engineering: building LLM-powered agents and RAG systems on top of the same production discipline (clean data flow, testing, and debugging) that my backend work is built on. Backend & Infrastructure - Languages: Node.js, Go (Golang), Python, TypeScript - Databases: PostgreSQL, MongoDB, Redis (SQL/NoSQL hybrid); pgvector for embeddings - Cloud & DevOps: AWS, Azure, GCP; Docker, CI/CD pipelines, Linux/VPS deployment - BaaS: Supabase, Firebase, Appwrite, AWS Amplify, PocketBase Frontend - Frameworks: React.js, Next.js, Vue.js, React Native, Capacitor, Flutter - Language & Styling: TypeScript, Tailwind CSS, Ant Design, Material-UI, Tailwind CSS, ShadCN Agentic AI Engineering - Frameworks: LangChain, LangGraph (stateful/multi-agent orchestration) - Patterns: RAG & agentic RAG, ReAct, tool/function calling, structured outputs, multi-agent workflows, MCP (Model Context Protocol) - LLMs: OpenAI, Anthropic Claude, open models via Ollama - Retrieval & data: vector databases (pgvector, Pinecone, Qdrant, Chroma), embeddings, semantic search - Observability & eval: LangSmith, Langfuse Testing & Quality - Test-Driven Development with Jest, Playwright, Cypress, Storybook, React Testing Library - End-to-end test pipelines and QA integrated across the development lifecycle Notable Projects - Serene Mind — a telehealth SaaS connecting therapists and patients with paid online sessions, built-in video/audio, and Stripe-style session payments. Next.js, React, TypeScript, Supabase, with custom CI/CD. (Core dev & tech lead) - SchoolBook — a finance, academics, and administration platform managing records for 1,000+ students across 20+ schools. React, Vite, TypeScript, Node.js, PostgreSQL. - GigGap — a skilled-labour marketplace for West Africa (electricians, plumbers, and other pros ↔ clients), live on both the App Store and Google Play. - Waziup IoT Lab — a learning platform for IoT serving 2,000+ daily active users. Go, React, Vite, TypeScript, PostgreSQL. (Lead developer) - Porai AI — an AI-powered math-solver app (in development). What Drives Me I build software that works and lasts. My approach centers on scalability, clean data flow, and user-centric design, and I like environments where I can investigate deeply, communicate findings clearly, and keep learning, most recently by moving into agentic AI. If you need someone who can own a problem end to end, let's talk.

I help businesses build reliable, production-ready mobile applications using Flutter. Whether it's developing a new product from scratch or improving an existing codebase, I focus on delivering maintainable, scalable solutions with a great user experience. I have experience building applications for Android and iOS, integrating REST APIs, Firebase services, authentication, push notifications, payments, maps, and offline functionality. I also develop backend services using Node.js and Firebase to support mobile applications. I value clear communication, realistic timelines, and writing code that is easy to maintain long after the project is complete. I provide regular progress updates and work closely with clients to ensure the final product meets their business goals.

15 + Years of Experience solcing technical problems that sit at the intersection of design, automation, and product logic. Your social media is quiet while your team ships product. Your reporting lives in spreadsheets nobody trusts. Your website has no visual weight and your bounce rate proves it. Your leads fall through before anyone qualifies them. Your content strategy exists but cannot scale manually. Your brand does not hold up at enterprise level. Your 3D assets sit in a folder instead of living on your site. Your internal knowledge leaves when people do. Your infrastructure decisions are being made reactively because nobody has documented the system you are actually running. Your trade workflow breaks the moment volume increases. Your sprints are moving but nobody can explain why. All of it is fixable. The difference is knowing whether the answer is a better system, a sharper design, cleaner code, or all three working together. ------------------------------------------------------------------------------------------------ AI and Automation is the core of most of what I build. On the architecture side I work with the OpenAI API, the Anthropic Claude API, custom local LLMs, and LM Studio to design the logic and data flow for custom AI agents. For workflow automation I connect systems end-to-end using n8n, Make, Webhooks, and REST APIs. I use Cursor, GitHub Copilot, Claude 3.5 Sonnet, and ChatGPT Advanced Data Analysis daily for prompt engineering and AI-assisted coding, which means I ship far faster than a traditional development cycle allows. For programmatic SEO I automate large-scale content strategies and site architectures using Ahrefs, Google Sheets, n8n, and the WordPress API. ------------------------------------------------------------------------------------------------ On the product and strategy side I run full delivery cycles using Jira, Linear, Notion, and Slack, and I have led scrum teams through complex builds with multiple stakeholder layers. Systems design and SOP automation is a discipline I apply rigorously, mapping logic in Whimsical, Miro, FigJam, and Notion before a single line of code is written. For IT strategy and technical documentation I work across Google Workspace, Notion, and Markdown environments. I have also designed software logic for cross-border trade and logistics systems, using Figma for logic mapping alongside n8n. and custom ERP dashboards. ------------------------------------------------------------------------------------------------ The design practice runs deep. I build advanced UI/UX in Figma with the Relume Library, specializing in component systems, variants, and interactive prototypes for complex software products. Technical dashboard design for industrial and financial interfaces is a particular focus, executed in Figma and Webflow. Typographically I love working within Swiss grid systems using typefaces, my favorite being like Neue Montreal, PP Machina and Google Sans. I also produce custom isometric icon sets and 3D iconography built in Blender, Figma, and Adobe Illustrator. For visual production I do studio-grade 3D rendering in Blender and KeyShot, interactive 3D web elements using Three.js, Spline, and WebGL, and product animation and motion graphics in Blender, Adobe After Effects, and Premiere Pro. I also handle 3D printing and hardware prototyping end-to-end using Bambu Studio and OrcaSlicer. ------------------------------------------------------------------------------------------------ On the development side I architect custom CMS builds using WordPress, Elementor Pro, and Advanced Custom Fields. I design UI/UX end-to-end in Figma, from early wireframes to production-ready component systems, variants, and interactive prototypes, pulling in resources like the Relume Library where they serve the work. Performance optimization runs through WP Rocket, JSON Minifiers, GTmetrix, and Google Search Console. Ecommerce solutions are built on WooCommerce with Stripe API integration. For DevOps and deployment I work across Vercel, GitHub, Docker, and local hardware environments. ERP and CRM customization is handled through Airtable, Make, and REST APIs. Database logic is architected across PostgreSQL, MySQL, Firebase, and Supabase. ------------------------------------------------------------------------------------------------ I am a Ugandan-based technologist working with clients across Africa and the world. Every engagement I take on is treated as a systems problem first: understand the constraint, design the logic, build for scale, hand over something that outlasts the project. ------------------------------------------------------------------------------------------------ On time and ownership of what you build: "Everything else belongs to others; time alone is ours." -- Seneca, Letters to Lucilius
