I build systems and then run them.
Rust services, the infrastructure that carries them, and payment rails between Europe and Central Africa. Three of the things below are running in production right now — you can click into them.
About
I like the part where a design meets a real machine. Most of what I build ends up needing both halves — the service and the thing that keeps it running — so I've stopped treating them as separate jobs.
Rust services
authkestra, an authorization orchestrator the Rust ecosystem didn't have — composed from config rather than wired by hand. Plus key-bound services and work on wallet recovery that needs no seed phrase.
Infrastructure
Kubernetes, Helm and Terraform aimed at workloads that are awkward to run: a Solana node on K8s, Talos clusters on bare metal, environments that come up in one command. Measured rather than assumed.
Payment rails
Moving money between Europe and Central Africa without the correspondent-banking tax — peer-to-peer escrow, bank-to-bank settlement over Open Banking, and the liquidity layer underneath.
Teams
Backend lead and code reviewer across multi-language teams at adorsys. Certified 24 junior developers in Linux, JavaScript and Java. Previously: a school-management platform used across Cameroon.
Work
Six things, grouped by what they are. The live ones are links — go and press the buttons.
Livexafp2p
Payment railsExchange currency without moving money across borders. Two synchronized local transfers plus escrow instead of one international wire — no SWIFT, no correspondent banking. Grew out of an earlier EUR/XAF liquidity marketplace.
Livevitepay
Payment railsPay by bank. Merchants generate a branded payment link in seconds, customers pay from their banking app, funds settle account-to-account — collecting for free instead of 2.5% to a card processor.
solana-validator-k8s
InfrastructureA Solana node on Kubernetes: portable Helm chart, disposable cloud layer, and a written contract between them. Publishes numbers nobody else does — peak memory, disk profile, and the client defaults that are wrong outside mainnet.
talos-hyper-v
InfrastructureTalos Linux Kubernetes clusters provisioned on Hyper-V. Immutable nodes managed entirely through an API — no SSH, no package manager, nothing to drift.
keybound-backend
RustKey-bound backend services. Part of ongoing work on non-custodial wallet recovery that needs neither a seed phrase nor a social login.
Tools
What I reach for, grouped by what I use it on.
Rust
Services, and the cryptography around them.
Infrastructure
Provisioned as code, observed by default.
Payments
The EUR ↔ XAF corridor, three ways.
Also
What the products are built on.
