Payments & settlement
Idempotent transaction flows, reconciliation pipelines, and integrations with payment providers and card networks.
Aldiger
Mehilli
Backend engineer focused on payments, distributed systems, and the reliability engineering that keeps fintech running in production.
About
I design and ship server-side systems for financial products — payment flows, message-driven workflows, and the operational surfaces that keep them running. My work tends to sit close to money movement, where correctness, idempotency, and recoverability matter more than velocity.
I care about clear contracts between services, predictable failure modes, and the unglamorous work of making systems observable and debuggable long after they ship.
Alongside client work, I run value.al, a software studio in Tirana.
Focus
Distributed services
Service decomposition, message-driven workflows, eventual consistency, retries, and dead-letter handling.
Operability
Structured logging, distributed tracing, dashboards, and runbooks — the surface area on-call teams rely on.
Working stack
C# / .NET
PostgreSQL
RabbitMQ
Redis
Docker
Blazor
Selected Work
A curated set of engagements across payments, distributed services, and reliability — clients anonymized where confidentiality requires. The shape of the work tends to be the same: money or operational state that has to move correctly across services, with auditability the user-facing teams can trust.
