Legacy System Modernization Company in Dublin

QServices is a remote-first consultancy serving Dublin companies in Tech, FinTech, and Pharma on legacy system modernization. We are not based in Dublin, but we work with Irish clients remotely with four hours of GMT morning overlap every weekday. No local office, honest remote model.

What Dublin buyers typically need from legacy modernization

Dublin's concentration of FinTech firms and regulated Pharma operations creates specific pressure on ageing codebases. The most common scenarios we see in similar markets:

• FinTech platforms under Central Bank of Ireland oversight that cannot risk a big-bang rewrite. They need a strangler-fig migration with a controlled, auditable cutover rather than a single risky go-live.
• EU GDPR data residency obligations that make lifting-and-shifting to cloud non-trivial. Personal data location and flow must be mapped and audited before any migration closes.
• Tech companies on .NET Framework or VB.NET whose original developers are retiring, leaving undocumented business logic locked inside the codebase with no safe way to extend it.
• Pharma software under GxP validation constraints where every change must be documented, tested, and traceable. Migration scope must be controlled tightly to avoid re-validation overhead.
• API modernization for open-banking and cross-platform data pipelines, common in both FinTech and Pharma environments across Dublin and Leinster.

The Central Bank of Ireland's operational resilience guidelines and EU GDPR are first-class constraints on any migration, not a post-project compliance exercise. We scope data handling, audit logging, and access controls at the architecture stage.

How we work with Dublin clients

Our team is based in India (IST, UTC+5:30). Dublin runs on GMT. The 5.5-hour difference puts both teams live simultaneously from 9:00 AM to 1:00 PM Dublin time every weekday. Four live hours covers daily standups, pull-request reviews, and milestone demos without requiring either side to work outside normal hours.

In practice a Dublin engagement runs like this: daily async updates posted to Slack or Microsoft Teams before your working day starts, a weekly 45-minute video review of completed work, and a sprint demo every two weeks with your product owner in attendance. Code lives in a shared repository with pull-request access open to your team throughout.

For architecture decisions and go-live approvals we schedule calls during Dublin business hours. On-site visits are available for critical phases, planned and billed separately. Most clients find a quarterly on-site week combined with daily async gives enough visibility without the cost of a resident team.

On data residency: we do not hold your production data. Development uses anonymised or synthetic datasets. Anything touching live systems runs inside a client-controlled environment with credentials you own and can revoke at any point.

Relevant work in similar markets

We do not have a published client reference in Dublin or Ireland. The two engagements below are the closest matches by service type and industry proximity.

Investment analytics platform (FinTech-adjacent): We replaced a spreadsheet-driven stock analytics workflow for an investment management firm with a role-authenticated Azure dashboard, automated data scraping, and real-time financial metrics including category-based stock classification, P/E ratios, and earnings schedule tracking. Moving scattered manual processes into a governed, auditable platform is the same pattern Central Bank of Ireland-regulated FinTech firms need from a legacy migration.

Global EHS platform, VB.NET monolith to .NET 8 and React: A global Environmental Health and Safety software company brought us in to rewrite a legacy VB.NET monolith. We used a phased strangler-fig approach rather than a big-bang rewrite, migrating modules to .NET 8 and React while keeping the live system running. The outcome was improved scalability and maintainability, with management of change, incident tracking, and LMS training consolidated in one platform. The same controlled-migration discipline applies directly to Dublin's Pharma environments where GxP traceability is non-negotiable.

What legacy modernization costs for a typical Dublin project

Engagements are priced in USD. Dublin clients handle EUR conversion on their end. Typical brackets for this service:

• Module-level migration ($60K–$120K, 16–24 weeks): One or two legacy modules migrated using strangler-fig with an API gateway introduced. Suitable for a single product line or team boundary.
• Full platform modernization ($120K–$300K, 24–40 weeks): Monolith decomposed into services, data layer migrated, CI/CD pipeline introduced. Right for a product that needs to scale or unlock features the old stack blocks.
• Large legacy estate ($300K–$500K, 40–52 weeks): Multi-system migration with integration surface mapping, embedded compliance controls, and managed transition support.

For engagements with EU GDPR compliance obligations or Central Bank of Ireland operational resilience scope, add 15–25% for compliance documentation and third-party review overhead. See the full pricing breakdown for what drives cost variation on this service type.

How to start working with us

Three steps: a 30-minute discovery call where we hear what your current system looks like and what it is blocking; a written scoping document delivered within five business days covering approach, timeline, and cost range; and a project kickoff once you approve the scope. No retainer before agreed scope.

Can you work with Dublin companies remotely?

Yes. Dublin is on GMT; our team is on IST (UTC+5:30). Both teams are live from 9:00 AM to 1:00 PM Dublin time, five days a week. We use Microsoft Teams or Slack depending on your preference, and all code is in a shared repository with review access for your team throughout the engagement.

On EU GDPR: we work inside your environment using credentials you control. No personal data transfers to our systems. The Data Protection Commission of Ireland sets the enforcement standard here, and our data handling approach is built around that. For Central Bank of Ireland-regulated clients, compliance documentation is scoped into the project from day one, not added at the end.
