Web and mobile applications
Customer portals, internal tools and mobile apps, designed around the people who use them and built so they are easy to change later.
Fintech and online trading
Fintech software from engineers who’ve worked inside regulated firms
Limassol is home to a large share of Europe’s online brokers, payment companies and forex firms. Our engineers spent years inside that world, at online brokerages and at a financial market data provider. We already know why compliance needs that extra field, and why the dealing desk can’t wait until tomorrow for a report.
Why it matters
We already speak the language
Most of the time on a fintech project goes into things a general agency would have to learn on your budget. These are the ones we bring with us.
-
Regulation shapes every feature
CySEC, FCA and ESMA rules decide what a client can see, when they can trade and what you have to keep and for how long. We put those requirements in the backlog from the first week instead of patching them in before an audit.
-
Onboarding is where clients are won or lost
Every extra step in registration and KYC costs you applicants, but a weak check costs far more. We build flows that are quick for genuine clients and thorough enough for your compliance officer to sign off.
-
Nothing runs on its own
A typical broker runs a trading platform, a CRM, several payment providers, a KYC vendor, a reporting tool and at least one spreadsheet nobody likes to talk about. The integrations between them are where most of the risk sits, so that is where we look first.
-
Money makes everything urgent
When deposits fail or prices lag, it is not a ticket for next sprint. We add monitoring and alerts from the first release, and we are used to fixing things calmly while the phones are ringing.
-
Auditors want evidence, not intentions
Access records, change history, data lineage and written procedures. We produce them as we go, so an audit becomes a matter of sending a folder rather than a month of archaeology.
What we build
Systems for brokers, payment firms and fintech teams
Some clients bring us one integration that keeps breaking. Others ask us to design a whole client platform. Both are welcome.
-
Client portals and onboarding
Secure client areas for account opening, KYC document upload, deposits and withdrawals, statements and support tickets, in the languages your clients speak.
-
Trading platform integrations
Connections to trading platforms such as MetaTrader and to liquidity providers, over FIX, REST and the platforms’ own manager APIs, covering account sync, group settings and trade reporting.
-
CRM, payments and KYC vendors
Integrations with CRM systems, payment service providers and identity checks, with daily reconciliation so finance can match every deposit to the right client account.
-
Back office tools and reporting
Internal tools for dealing, compliance, finance and support teams, and the Monday morning reports management keeps asking for, produced automatically.
-
Regulatory reporting data
Clean, traceable datasets for transaction reporting and regulatory returns, with a clear record of where every figure came from and who changed it.
-
Market data pipelines
Collecting, cleaning and distributing prices, reference data and corporate actions for analytics, risk and the tools your clients see.
-
Distributed ledgers, where they fit
Our team includes a Corda certified developer, so we can judge ideas built on a shared ledger with real knowledge. We will also tell you honestly when an ordinary database would do the job better.
Security and audits
Built to pass the questions before they are asked
Security is part of every task, not a phase at the end. One of our engineers is a Certified Ethical Hacker, and we review our own work the way an attacker would.
- Access granted by role, with every privileged action logged.
- Encryption in transit and at rest, with keys held in a managed vault.
- Personal data kept to a minimum, masked outside production and deleted on schedule.
- Full change history for code and infrastructure, so you can show who changed what and when.
- Independent penetration tests welcomed, and findings fixed promptly.
- Documentation written with your auditor’s questions in mind.
Services
What fintech clients ask us for most
Every fintech project uses a different mix. These four cover most of what we do for brokers and payment companies.
Data engineering and AI
Pipelines, lakehouses and reporting on Databricks and Python, so your numbers are right and your AI plans have something solid underneath.
Cloud and DevOps
Azure and AWS setups that are secure, automated and sensibly priced. We also tidy up the ones that grew by accident.
Software development as a service
Senior developers who join your team for as long as you need them. No recruitment fees and no months spent getting up to speed.
Questions
What fintech teams usually ask
Something more specific? Email info@avientiq.com and an engineer will reply.
Do you have experience with CySEC regulated firms?
Yes. Our engineers have worked inside brokerages regulated by CySEC and the FCA, and at a financial market data provider. We understand the obligations around client money, record keeping and reporting, and we always work alongside your compliance team rather than overruling them.
Can you integrate with our trading platform?
Most likely. We have worked with the manager and reporting APIs of common retail trading platforms, with FIX connections, and with a long list of CRM systems and payment providers. Tell us what you run and we will confirm quickly whether we have done it before.
Can you take over a system another vendor built?
Yes, and it is a common starting point. We begin with a review of the code, the infrastructure and who has access to what, then agree a plan to make it stable before adding anything new.
Do you work with firms that are still applying for a licence?
We do. We can help plan the technology side of your application, choose vendors and build what you need to go live. We will also be straight with you about what can wait until after launch.
How do you handle confidentiality?
We sign your NDA before any detailed conversation, work inside your own accounts and repositories, and never reuse one client’s code or data for another.
