I help UK agencies and businesses build and ship iOS apps. I can join your team, take ownership of iOS delivery, or help improve a complex codebase.
Open to contracts, project delivery or ongoing support, with a working arrangement that fits your team.
tim@timrichardson.coAgency client projects, consumer apps used at national scale, and products owned from the first build through years of releases.
Senior / Lead iOS Engineer
A national-scale SwiftUI marketplace, built across multiple product squads.
Contributed to the marketplace app and shared components, and owned the companion App Clip.
The App Clip handled over 70% of the organisation’s photo uploads.
Lead iOS Engineer · Contract
Agency delivery across several large, established client codebases.
Led iOS engineering across client projects, getting productive in unfamiliar codebases, often concurrently.
Hands-on delivery spanning SwiftUI, API design, performance, CI, code review and mentoring.
Lead iOS Engineer / Engineering Lead
A global consumer product built from the ground up.
Owned the SwiftUI app, subscriptions, analytics, release pipeline and App Store delivery.
Shipped and operated the product through three years of iteration, with localisation into 30+ languages.
Extra iOS capacity for a busy delivery period, cover for an existing engineer, or a senior contributor for a longer contract. I work alongside your designers, project managers and engineers.
A new app, a substantial feature or a client project that needs someone to take responsibility for iOS, from technical planning through implementation and release.
An independent review, a difficult performance issue, a modernisation project or ongoing technical advice. I can investigate, implement and help your team take the work forward.
I am comfortable working with your account and project managers, joining client conversations, and representing your agency as part of the delivery team. At Hanno, I led mobile engineering and worked directly with the client; at Unblu, I supported client engineering teams integrating the iOS SDK.
Full-time or part-time, remote or on-site: I am happy to discuss the arrangement, working hours and duration that suit your team.
Alongside day-to-day engineering and feature delivery, I offer focused support when a codebase needs a closer look.
Get an inherited, abandoned or unstable app back into a state where it can build, ship and improve safely.
An independent assessment with evidence, prioritised findings and a practical roadmap.
Diagnose repeat crashes, slow launch, scrolling hitches, memory growth and main-thread problems.
Adopt Swift 6, structured concurrency, SwiftUI and healthier architecture without stopping product delivery.
Senior iOS judgement for a few hours each month, without hiring a full-time lead.
Human review of AI-generated Swift code before customers, investors or App Review discover the risk.
Send me the brief, the role you need to fill or an outline of what is coming up. I am happy to discuss how I could fit into your team.
