Hi, I'm Moses Morris, a Software Engineer, Data Engineer, and AI Specialist with 6+ years of experience, serving clients globally. I sit at the intersection of three things most developers only do one of: I build production systems (Python/Django/Flask backends, full-stack apps, ETL pipelines), I train and evaluate AI (coding roleplay tasks, QA auditing of annotator work, persona-based evaluation for LLM behavior studies), and I write about all of it clearly (technical documentation, API guides, developer content). That combination means I don't just ship code, I can also assess whether an AI model's output on that code is actually good, and document the result so your team or your model can learn from it. What I bring to a project: Full-stack & backend engineering - Python (Django, Flask, FastAPI), JavaScript/Node.js, React, PHP (Laravel), and C, with production databases (PostgreSQL, MySQL, Redis, MongoDB). Data engineering - ETL pipeline design and troubleshooting, data pipeline foundations, structured data strategy. AI evaluation & training data - multi-turn coding roleplay evaluation, RLHF-style annotation QA, persona-based scenario testing, experience inside Microsoft Research-grade AI behavior studies. Technical writing - certified technical writer; I document what I build, which most engineers skip and most clients end up needing anyway. What differentiates me: Most freelancers offer either "I code" or "I write." I offer the full loop - build it, verify the AI/data behavior around it, and hand over documentation that a non-technical stakeholder can actually read. I also apply a Design Thinking lens (user-centered problem framing, persona development) to engineering and AI-eval work specifically - useful when the "user" is a customer, and just as useful when the "user" is the model you're trying to align. Sector experience: - E-commerce — designed and built Vantage Market, a solo luxury e-commerce platform (Flask, PostgreSQL, Redis, React, Docker). - AI/ML training & evaluation — ongoing AI evaluation contract work, Microsoft Research AI Behavior Study (Python/FastAPI in a cloud Dev Box environment). - Nonprofit/community — Kwetu Charity Organization, church community technology projects. - Healthcare admin/IT — Ngurubani Medical Services (ICT support, finance operations).

Industry Experience

Consumer Goods, Computers & Electronics, Gaming, Healthcare, Government, Other, Software & Internet, Media & Entertainment, Telecommunications, Non-Profit Organization, Education, Professional Services
    Elite Scholars - Tertiary Education Support Platform
    An education support platform built for students preparing for tertiary/college admissions and success. What it solves: Most education platforms lead with feature lists (courses, portals, resources) before establishing why a student should trust them with something this important. This site leads with the emotional stake, opportunity and support, then backs it with a clear registration flow and e-learning feature breakdown. Highlights: Registration flow built for a high-volume "Registration Ongoing" period. E-learning feature breakdown (resources, benefits, essential features). Mobile-first responsive build, since most target users land on it from a phone. Green-on-white color system chosen deliberately for trust and legibility. Tech Stack: HTML5, CSS3, JavaScript, React, Node.js, Figma. edtech webdeveloper fullstackdeveloper uidesign responsivedesign reactjs education mobiledesign
    Swift Offers - Multi-Category E-commerce Platform
    An e-commerce marketplace built for the Global market -electronics, groceries, fashion, and more under one roof, with local pricing (KES, USD, EUR, JPN) and delivery logic from day one. What it solves: most template e-commerce builds ignore local context (currency, delivery zones, category mix). This one was built around the delivery reality from the start. Highlights: Category browsing, live discount badges, and promotions carousel. Cart, newsletter signup, and checkout flow. Backend logic for product and pricing management. Tech Stack: Python, Django, Flask, PostgreSQL, React, Redis, Docker, REST API. ecommerce fullstackdeveloper webdeveloper python django reactjs onlinestore postgresql docker AWS
    Escape - Travel Booking Platform
    booking platform for a travel agency, built around how people actually search for trips - by feeling and activity, not just destination name. What it solves: most travel sites make you browse by country first. This one leads with activity cards ("swimming in open water," "diving in caves") so intent-matching happens faster. Highlights: Destination detail view with pricing, gallery, and booking confirmation flow Activity-first browsing structure Fully responsive, mobile-first layout Tech Stack: HTML5, CSS, JavaScript, React, Tailwind, CSS, Figma, Vercel. webdesigner uxdesign travelapp frontend responsivedesign webdeveloper nodejs reactjs mongodb
    CloserTune - Consultancy Growth Landing Page.
    A landing page built for my own agency, CloserTune. The brief: turn "we do consulting" into something a home service business or property agent would actually stop and read. What it solves: generic consulting sites blend together, this one speaks to three client verticals directly instead of using broad "we help businesses grow" copy. Highlights: Deep purple and coral color system with a custom illustration carrying the visual weight Vertical-specific messaging (consultancy, home services, property sales) Fully responsive layout, built and deployed end-to-end Tech Stack: React, Node.js, Express, MongoDB, REST API, CSS3, Figma webdesigner webdeveloper landingpage uidesign fullstackdeveloper frontend branding
