Built for trust
Delivery shaped for systems that matter, not low-context production lines.
About SISI
A small Irish studio for serious technical work.
SISI Solutions helps teams move important systems with more clarity and less friction — across software engineering, cloud delivery, AI automation and security execution — without turning the work into a black box.
What this studio is built on
Three working attributes
Readable execution
Clear decisions, visible progress and fewer hidden technical surprises.
Human partnership
Direct collaboration with technical depth and commercial clarity.
Ireland advantage
European base, practical overlap, local accountability.
SISI Solutions operates under Sevilla Tech Solutions Limited, headquartered in Carrick-on-Shannon, County Leitrim, with a delivery rhythm that works naturally across Ireland, the UK, mainland Europe and early US collaboration windows.
What we optimise for
Less ambiguity. Better decisions. Stronger delivery.
The studio came from delivery contexts where failure meant delays, audit pain, operational risk or real business cost. That's why the style is practical by design: fewer layers, cleaner communication, and engineering that holds up once it's live.
Security in the build pathNot audited in after the fact.
Readable deliveryClients can see the work as it moves.
Release disciplineMatters as much as implementation speed.
Engineering timeline
The brand is recent. The delivery pedigree is not.
A short view of the engineering path that led into the current studio.
2017 – 2022
Foundation
Early delivery centered on high-volume regional platforms and practical systems with public and private impact, before the SISI studio model existed as such.
- Academic registry systems for large institutions
- Civic digital platforms supporting local operations
- ETL pipelines for compliance and monitoring workflows
2023
Operational Systems
The work moved into field operations and payments — systems where real-time state and regulatory controls both mattered.
- SAP-integrated fleet maintenance with offline-first field tools — Fleet Maintenance System
- White-label payment gateway with PCI-DSS Level 1 tokenization — BICHECKOUT
2024
Enterprise Depth
Calculation-heavy, audit-sensitive work — the kind where a spreadsheet error has real financial consequences.
- Actuarial calculation platform, runtime cut from hours to minutes — APEX System
2025
Regulatory Delivery
Direct delivery for a regulated banking environment, where every report has to hold up under audit.
- Banking compliance reporting engine, -85% report generation time — LAAD Compliance Report
Next step
If the system matters, the way it gets carried matters too.
