Tim RichardsonFreelance iOS engineer
Services

From extra team capacity to owning iOS delivery.

I work with agencies and product teams on new apps, feature development, ongoing delivery and specialist iOS work. Open to contracts, project delivery or ongoing support, with a working arrangement that fits your team.

Ways to work together

  • Join your teamExtra 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.
  • Own iOS deliveryA new app, a substantial feature or a client project that needs someone to take responsibility for iOS, from technical planning through implementation and release.
  • Bring specialist supportAn 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.

Part of your delivery team

I work with designers, engineers, QA and project managers, and am comfortable joining planning, reviews and client conversations. I can represent your agency as part of the team, with responsibilities and client communication agreed together.

Full-time or part-time, remote or on-site: working hours, duration and the shape of the engagement can be agreed around your project.
