Expertise

Native Apple development, no shortcuts.

No hybrid framework, no abstraction layer that ages badly. Swift, Apple's own frameworks, architecture decisions I can justify — and for the past two years, AI agents that take on the tedious work.

Native iOS development

Swift, SwiftUI, UIKit and Objective-C across iOS, watchOS, macOS and tvOS. Combine, RxSwift, async/await, Bluetooth BLE, Firebase.

Architecture & quality

Clean, maintainable, testable code: SOLID, Clean Architecture, MVVM-C, unit tests, technical debt reduction.

Agentic engineering & AI

Designing AI-assisted agents and developer tooling: Claude, Hermes, MCP servers, multi-agent orchestration, skill development.

Management & Agile

Leading teams of up to 7 people, hiring, continuous training, code reviews. Agile Scrum and Kanban, two-week release train.

CI/CD & release

Bitrise pipelines, signing, TestFlight, App Store submission and release management. Crash-free rate and performance monitored in production.

Security & compliance

Keychain, encryption, App Transport Security, secret management, GDPR and regulated-sector requirements — fintech experience at Bankin'.

AI-assisted development
New

Agentic code is not a gimmick.

Since 2024 I have put AI at the centre of my workflow — not to generate code blindly, but to build specialised agents that absorb the repetitive work: migrations, test coverage, first-pass review, documentation. The payoff is measured in weeks of delivery, never at the expense of human review.

Method

How an engagement runs

A simple framework, proven over fifteen years, that keeps surprises off the table for both sides.

01
First conversation
30 minutes to understand the context, the existing codebase and the goal. No commitment.
02
Scoping & proposal
A written scoping note: perimeter, technical risks, effort estimate and timeline.
03
Iterative development
Regular TestFlight builds, weekly progress checkpoints, systematic code review.
04
Delivery & handover
Release, technical documentation and handover to your team. Post-delivery support available.
