Payment integrations
PSP wiring, webhook reliability, settlement reconciliation. We have integrated global payment providers for trading platforms and fintech — so we know where the edges are.
A software studio · Tirana, Albania
Software engineering, the careful kind.
We build payment integrations, internal tools, and the unglamorous backend systems that businesses run on. A small team of senior engineers with a decade in fintech and payments — and no consultancy theatre.

Services
We build the parts that must not fail.
APIs & integrations
REST APIs, API gateways, third-party integrations. Clean contracts and predictable versioning, so the systems you connect to do not become the systems that wake you up.
Backend microservices
.NET, PostgreSQL, RabbitMQ, Redis. Event-driven systems that survive contact with production traffic.
Cloud & delivery
Azure, Docker, CI/CD pipelines. Repeatable deployments and the release plumbing that lets you ship on a Tuesday without holding your breath.
Internal tools
Blazor admin panels, dashboards, automation. The boring software your team needs, built well and shipped fast.
Code rescue
Legacy codebases, half-finished projects, brittle migrations. We come in, stabilise, document, and leave it better than we found it.
Approach
We optimise for boring outcomes.
i.
No surprise invoices. Fixed-scope pricing wherever we can estimate it honestly — hourly only when that is the fairer way to bill.
ii.
Code that reads well a year from now. Tests where they matter. Docs for the next engineer.
iii.
We say no to work we are wrong for. A good referral beats a bad outcome, every time.
iv.
One architect owns every design. Systems here are designed by Aldiger Mehilli — software architect, ten years in payment and trading backends — and built by the people who will answer for them.
Client work
We have shipped this before.
-
Online FX / CFD trading broker
Multi-PSP routing for an FX & CFD broker
One provider's outage no longer fails a deposit — an affected corridor falls back to another PSP on the same request, instead of returning the trader an error. Onboarding a new provider dropped from weeks to days.
-
Compliance & licensing SaaS
API gateway for a regulated B2B platform
Partner integration time dropped from weeks to days. Security policy is now enforced in one place rather than audited per service.

Online trading broker
Performance tuning of a trading platform's hot path
The endpoints that were breaching their tail-latency budgets now hold them through market open — and each budget is enforced per endpoint in CI, so a regression fails the build instead of reaching traders.
Open source
We open-source the sharp edges.
Remit
A reference money-movement backend for brokers and fintechs: deposits and withdrawals through payment providers, a double-entry ledger, reconciliation — with every decision written down. Idempotency keys and state machines, outbox and inbox, signed webhooks, one trace per movement, AKS by Bicep with workload identity. Nine ADRs, a threat model, SLOs, 65 tests against real PostgreSQL and RabbitMQ.
Countersign
Two-direction request signing and webhook verification for payment integrations: sign outbound, verify inbound — with the constant-time comparison, replay checks, and exact-byte handling that are easy to get subtly wrong. Dependency-free .NET.
