Development & Engineering

Complex systems, built right. Custom SaaS, mobile apps, AI integration, fintech infrastructure — full-stack, production-grade, battle-tested.

The gap between "we have a spec" and "we have a system in production" is where most software money gets lost. T2 engagements close that gap: architecture that survives growth, code that a new engineer can inherit, and a build process that doesn't collapse when requirements shift.

What's included
Custom web apps & SaaS platforms
Full-stack product engineering: from schema design and API architecture through to production deployment and runbook. I build systems intended to be maintained and extended by your team, not just to demo.
Mobile apps — iOS, Android, React Native
Cross-platform mobile with native feel — using React Native for shared codebase or native Kotlin/Swift where the platform demands it. App Store and Play Store submission handled.
AI integration & multi-agent systems
Practical AI that ships: LLM-powered features, retrieval-augmented generation, multi-agent orchestration with CrewAI or custom PHP agents. Built for production reliability, not Jupyter notebook demos.
Fintech & payment systems
KYC/KYB flows, regulated crypto infrastructure, payment rails, wallet architectures — built to the compliance standard of the jurisdiction, not just the happy path.
APIs, backends, cloud infrastructure
REST and event-driven backends, cloud-agnostic infrastructure-as-code, CI/CD pipelines, and observability stacks. I write the runbook as part of the build, not as an afterthought.
Example engagements
How we price

Project-based · fixed scope where possible

From €15k for focused builds; larger multi-phase platforms run €40k–€200k+. Fixed scope + timeline where the problem is clear; T&M where it's genuinely exploratory. Every engagement starts with a written plan — approach, cost band, risk — before any code is committed.

Not included

Infrastructure and hosting costs, third-party API fees, app store fees, ongoing support after handover (T4 covers that).

FAQ
Do you hire specialists or build it all yourself?

For most engagements I work as the lead architect and primary engineer. For larger projects I bring in trusted specialists — mobile, security, design — scoped and managed by me. You always have a single point of accountability.

How do you handle scope creep?

Every engagement starts with a written scope document. New requirements discovered mid-build are logged, triaged, and either folded into the current scope with a revised timeline, or deferred to a follow-on phase. Nothing is silently absorbed and invoiced later.

What's your documentation standard?

Architecture decision records (ADRs) for major choices, a runbook for deployment and incident response, and inline code documentation for anything non-obvious. You should be able to hand the codebase to a new engineer without a week of knowledge-transfer calls.

Can you ship in our existing team's stack?

Usually yes — I'm production-fluent in TypeScript/Node, PHP, Python, Kotlin, and the major cloud platforms. If your stack is something unusual, I'll say so upfront and we'll agree whether to adapt or standardise.

What happens if we need to pause mid-build?

Life happens. We'll document the current state, commit everything clean to version control with a handover note, and agree a re-entry process. Work already completed is yours — no ransom clauses.
