How we work

A structured, transparent process — you have full visibility at every stage, from the initial scoping call through to production deployment and long-term continuity.

01
Weeks 1–2
Discovery & Scoping
Requirements analysis, constraint mapping, and threat modelling for security-sensitive projects. Delivered as a fixed-cost scope document with a proposed timeline and architecture outline.
02
Weeks 2–4
Architecture & Design
System design, API contracts, and data model definition run in parallel with UI/UX design. You review and approve everything before a line of application code is written.
03
Ongoing
Development
Two-week sprint cycles, daily standups, and weekly client demos. Continuous integration from day one. You have access to a staging environment throughout the entire build.
04
Pre-launch
QA & Security
Manual and automated testing, load benchmarking, SAST/DAST security scanning, and regulatory review where applicable. No shortcuts before production sign-off.
05
Launch +

What clients say

Feedback from engineering leaders and decision-makers who've worked with us — in their words, unedited.

"

We ran a formal RFP with four vendors. The first three all proposed React Native wrappers and called it 'native.' SDT submitted a Kotlin module architecture diagram — unprompted — before we'd even issued the formal brief. The codebase went through our internal Android chapter review without a single structural comment. That has never happened before.

Kostas D.
VP Engineering · Digital Banking Platform
"

What sold us wasn't the demo — it was watching their backend engineer explain query plan optimisation to our DBA, unrehearsed, in the first technical call. The fleet platform has been running 340 vehicles across four countries for two years. One P1 incident total, resolved before our on-call rotation had even responded.

Marek J.
Director of Operations · European Logistics Group
"

Our security auditors arrived expecting to spend a full day on the PQC implementation review. They were done in under two hours. The lead auditor spent the rest of the session asking SDT's engineer about Dilithium key rotation strategy. That's the first time I've ever seen auditors turn into students.

Head of Information Security · Defence Contractor
"

Eleven years of paper archives, 2.3 million documents, and our legal team needed to actually trust the search results — not just see them. Ninety-four point seven percent classification accuracy, out of the box. The cases flagged for manual review were genuine edge cases. Not lazy misses.

Irini S.
Head of Digital Transformation · Insurance Group
"

They migrated a live betting platform — RNG certification and all — without a single session interruption across a 72-hour deployment window. What impressed me more was the rollback plan: staged, documented, tested, ready at every step. They never needed it. But I knew they'd have been calm if they had.

Before you reach out

Answers to the questions that come up in most first calls — so you can walk in with the ones that actually matter.

Yes — always and without hesitation. We treat every engagement as confidential from the first conversation. We can work from your standard NDA or provide ours. Everything is signed before any technical discussion begins.
We take on projects from around €15,000 for well-defined, bounded deliverables. Our typical engagement sits between €30,000 and €200,000. For ongoing team augmentation and retainer support we work on monthly terms with clearly defined scope.
Both, depending on the engagement. For clearly scoped deliverables we prefer fixed-price — it aligns incentives and removes budget uncertainty for you. For longer, evolving work we use time & materials with monthly caps and a transparent burn report every two weeks.
Yes — team augmentation is a meaningful part of what we do. We've embedded individual senior engineers and full squads into client engineering organisations. We adapt to your existing Git workflows, code review culture, sprint cadence, and tooling from day one.
You do — in full. All intellectual property, including source code, designs, documentation, and any proprietary tooling built during the engagement, transfers to you on final payment. We retain no licence, re-use, or portfolio display rights without your explicit written consent.
We offer retainer-based support with tiered SLA response times — from 4-hour critical response through to next-business-day standard. We also offer clean handoff-only engagements: full runbook documentation, knowledge transfer sessions with your team, and a defined warranty period.
Yes. We've delivered into banking (PSD2, GDPR, EBA guidelines), defence (NATO-aligned security standards, air-gapped deployments), gaming (RNG certification, responsible gambling compliance), and document-intensive enterprises requiring ISO 27001-aligned audit trails. We understand what compliance and procurement teams need to see before sign-off.
