ISO 8583 & host integration
Authorization messaging, integration with a national switch, transaction timelines, chargebacks and clearing files.
TECHNICAL LEAD & AI ENGINEER
I build AI products
and the systems
that run them.
Agent orchestration, generative AI and reliable backends, on years of card-payment engineering. I connect the pieces and own the delivery, from architecture to production.

CARD PAYMENTS · MONÉTIQUE
From the terminal
to the switch.
Years of payment engineering behind every system I build: card transactions, terminals, scheme certification and the backends that settle them.
Concept artworkEMV, terminals & SoftPOS
Contact and contactless card payments, end-to-end payment-terminal integration and SoftPOS.
Scheme certification
Certification work for payment applications with Visa, Mastercard and American Express, using FIME test tools.
Wallets, QR & loyalty
Mobile wallets, QR code payments, fuel-station payments and loyalty platforms, including a telecom loyalty platform at 10M+ transactions a day for 12M+ customers.
SELECTED ENGINEERING EXPERIENCE
Complex systems.
Thoughtful execution.
A look at the products and infrastructure I work on. Product details are intentionally kept private.
Concept artwork01 / GENERATIVE AI
A platform for
multimodal creation.
Connecting image, video, speech and music generation into usable product workflows. Shared provider APIs, model routing, asynchronous jobs and tools that agents can use.
Concept artwork02 / FINTECH
The infrastructure
behind a transaction.
Payment, wallet and loyalty systems built around transactional integrity. ISO 8583 and EMV flows, terminal integrations and the operational work that keeps them running.
Concept artwork03 / SAAS & OPERATIONS
Software that keeps
operations moving.
Full stack SaaS platforms: memberships and registrations, Stripe payments and subscriptions, invoicing and refunds, scheduling and logistics. From data models and integrations to Docker and AWS deployments.

Stadium ticketing
Waiting room, atomic seat holds, card payment, e-tickets by email and WhatsApp, and an offline rotating QR at the gate.
02 / 06 · 1:06
Telecom loyalty at scale
10M+ transactions a day for 12M+ customers: pods behind a load balancer, autoscaling and failover.

Multimodal AI platform
Many AI providers behind one API: capability routing, fallbacks, async jobs, credit quotes and agent tools.
HOW I WORK
A technical lead.
A hands-on builder.
I work across product boundaries, connect agents to real tools and stay close to implementation.
01AI agents & orchestration
Coordinate scoped work across planning, implementation, debugging, review and testing. Connect assistants to tools with MCP and automate workflows with n8n.
02Generative AI & local models
Build image, video, speech and music workflows with hosted APIs. Use Ollama for local LLM inference experiments and workflow prototyping.
03Card payments & monétique
Design and integrate ISO 8583 and EMV payment flows, terminals and SoftPOS, and support scheme certification with Visa, Mastercard and American Express.
04Backend architecture & cloud
Design transactional APIs and data models, SaaS billing with Stripe (subscriptions, memberships, invoicing, refunds), containerize services and work through production incidents and cloud delivery.
05Product integration & publishing
Bring web and mobile products through integration and publishing workflows across app stores, browser extensions and ChatGPT apps and plugins.
WORKING TOGETHER
Fully remote.
One-off or ongoing.
I work 100% remote: reinforcing your team for a one-off need or ongoing missions, or leading it. We shape the relationship around the work.
100% remoteFull-time
A technical lead or engineering role with long-term product ownership and a distributed team.
Freelance
A focused delivery, an integration, an AI workflow or a technical problem that needs experienced hands.
Independent projects
Architecture and implementation for a defined product, platform or engineering initiative.
WHAT I CAN TAKE ON
- Build and harden SaaS platforms, from architecture to production
- Stripe integration: payments, subscriptions, memberships, invoicing and refunds
- Card payments: ISO 8583, EMV, terminals, SoftPOS and scheme certification
- AI agents and GenAI features wired into your existing stack
- Security, scalability and AWS infrastructure for products that must hold up
- Lead your team, or reinforce it for a one-off need or ongoing missions
