I turn manual business workflows into AI-powered systems. Recent example:
an established roofing company came to me drowning in manual quotes and
follow-ups.
WHAT I DO FOR YOU
- AI workflow automation — quotes, document processing (OCR + extraction),
client communications, CRM enrichment, using Claude/GPT APIs
- AI assistants on YOUR data — chatbots that answer from your documents,
catalogs and procedures (RAG), deployed securely
- Cloud & DevOps foundations — Kubernetes, GCP/AWS, CI/CD, Docker:
the infrastructure your automation runs on reliably
WHY ME
- 10+ years of cloud architecture & digital transformation across Africa
including a reinsurance platform serving 200+ insurance companies
- Bilingual French/English
HOW WE START
Book a consultation, or message me with one workflow that eats your
team's time. I'll reply within hours with a concrete automation approach
— and a fixed-scope entry offer (10–15h) so you can test me at low risk.

Most software projects don't fail because the code was hard.
They fail because the wrong decisions got made in the first two weeks, and someone paid for that later with a rebuild.
That is the part I care about most.
I run Posybl, an AI-native software studio. Along the way, I've built for names like Sony, PepsiCo and Ericsson, as well as founders and small teams who just needed their idea to work.
I don't only write the build. I help you pick the right path before a single workflow is created, so you spend money once instead of twice.
What I build
• SaaS platforms
• Startup MVPs
• Marketplaces
• CRM and ERP systems
• AI-powered apps
• Internal tools
• Client and staff portals
• Booking and scheduling systems
• Inventory platforms
• Dashboards and reporting
• Workflow automation
• Custom web apps that don't fit a template
How I build it
I choose the platform and architecture based on what the product actually needs. My team and I can launch lean, integrate the right services and scale the infrastructure as the product grows:
• Node.js
• Next.js
• PostgreSQL
• Supabase
• Neon
• Xano
• REST and GraphQL APIs
• Stripe and Stripe Connect
• OpenAI and Claude integrations
• Twilio
• Google APIs
• Airtable
• Make(.)com and n8n
So you're not hiring "a generic AI guy". You're hiring someone who can start you lean and move you onto heavier infrastructure the day your growth demands it.
Where I've worked
• Healthcare
• Fintech and financial services
• Construction
• Education
• Logistics
• Property
• Manufacturing, and
• Professional services.
Real projects have included AI education platforms, Financial applications, Compliance and Document Systems, Quoting and Estimating tools, Customer portals, Inventory Management, and End-to-end automation.
What every build gets, by default
Secure. Scalable. Fast on mobile and desktop. Easy to maintain instead of held together with patches. And shaped around how your business actually runs, not around whatever was easiest to code.
How I work
I start with the problem, not the feature list. I'll pressure-test your idea, flag the risks early, recommend an architecture that won't box you in, and build something that can grow with you. A lot of my clients launch a lean Bubble MVP to validate fast, then layer in Node.js, Supabase, Postgres or custom APIs as usage climbs. The goal never changes, software that returns real business value.
Founder with a raw idea, or an established team modernising old systems, either way I'm happy to talk it through. If you want a developer who pairs the technical side with commercial judgement and clear, honest communication, let's have a conversation about what you're building.

I build production systems where AI actually has to work — not demo it.
Over 8,800+ hours on Upwork (100% JSS, Top Rated Plus), I've shipped Claude and OpenAI integrations, MCP servers connecting agents to live business data, and automation pipelines that run unattended in production — handling real users and real financial data, not sandbox traffic.
✅ AI in production — Claude & OpenAI integrated into live SaaS handling real load, plus MCP server development connecting agents to real systems
✅ Automation that doesn't silently fail — n8n & Inngest pipelines with durable execution and idempotent step writes
✅ Built for scale — Kubernetes-deployed apps maintained across 2,400+ production hours.
✅ FinTech-grade reliability — APIs and pipelines for an alternative-assets platform where correctness isn't optional
✅ End-to-end ownership — Postgres schema to Docker/Kubernetes deploy to the pager going off at 3am
Core stack: TypeScript, Next.js, NestJS, PostgreSQL, Redis, Docker, Kubernetes, AWS, Claude API, LangGraph, RAG/pgvector, MCP, n8n, Inngest, Stripe/Stripe Connect, Prisma, Supabase, Shopify, Go, Kafka, Terraform.
If you're integrating AI into an existing system, building an MCP server, automating a manual workflow, or scaling a SaaS product without breaking what already works — send me a message with what you're building.

I'm a full stack developer specializing in React, Node.js, and TypeScript. I build production web applications that handle payments, user data, complex workflows, fintech platforms, admin dashboards, SaaS products, and AI-powered automation tools.
As a full stack developer, I've shipped 20+ production applications for clients across the UK, Australia, South Korea, Hong Kong, Netherlands, and Zambia. My full stack development work includes Stripe payment systems processing automated payouts, admin panels managing thousands of users across multiple roles, real-time dashboards with WebSocket data feeds, mobile money integrations for African markets (MTN, Airtel, Zamtel), and AI features using OpenAI and Claude APIs.
Most of my full stack developer projects involve taking a business idea or existing codebase and turning it into something that works at scale. I handle both frontend and backend development, building the user interface, designing the API architecture, setting up the database, and deploying to production. Clean architecture, documented code, and systems that don't break when you scale.
What I work with most:
Frontend: React, Next.js, TypeScript, Tailwind CSS, Zustand, Framer Motion
Backend: Node.js, Express, Supabase Edge Functions, REST APIs, WebSockets
Databases: PostgreSQL (Prisma), MySQL, MongoDB, Redis
Payments: Stripe (Connect, Webhooks, PaymentIntents, Subscriptions), Mobile Money (MTN, Airtel, Zamtel)
AI Integration: OpenAI GPT-4o, Anthropic Claude API, custom automation workflows
Cloud & Deployment: AWS, Netlify, Railway, Vercel, DigitalOcean
Industries I've worked in:
As a full stack developer, I've built applications across fintech, healthcare, education, transportation, SaaS, e-commerce, and marketing automation.
How I work:
I handle projects end-to-end from architecture decisions to deployment. I work solo on most builds, but I also co-founded Fluxium Agency, which means if your project needs to accelerate or something unexpected comes up, I can bring in additional developers without missing a beat. You always deal with me directly no middlemen, no handoffs.
If your project involves building a web application, integrating payments, setting up admin dashboards, or connecting APIs send me a message. I'll be honest about whether I'm the right fit.
