New assessment
Prepare for the interview you actually have
A few questions about your platform, your timeline and what is weakest right now. You get one focused next step, not a reading list.
New free guide
Why you didn't get the offer
Seven reasons engineers lose offers they deserve, written from the hiring side. Free, 34 pages.
New tool
LineUp CV workspace is available
Build and tailor a CV, match it to a job, create a cover letter and LinkedIn headline, review readiness and export the finished PDF.
Book launch
SwiftUI under load is now available
A production SwiftUI book about performance, Swift 6 concurrency, state, UIKit migration, tests and CI, taught through failures you can reproduce.
Engineering Interviews
You have 40 interview tabs open and still don't know what to study.
Interview preparation gets worse when everything looks important. The closer the interview gets, the more your calendar should force you to cut.
Engineering Interviews
You watched the solution. Then you opened an empty editor.
Watching someone else code can make you feel ready. Live coding exposes the difference between recognition, retrieval, and making your judgment visible under pressure.
Engineering Interviews
AI can pass the assessment. You still have to survive the interview.
AI can produce a polished technical assessment. The harder part starts when another Senior engineer asks why the code exists and whether you actually own the decisions behind it.
Interviews
What interviewers score while you share your screen
The code is only one part of a live round. The interviewer is also recording how you frame, choose, verify and recover while the screen is shared.
Interviews
React Native interviews happen at the boundary
The framework answer is only the surface. Senior judgment appears where JavaScript, native work and product constraints meet.
Interviews
Test automation is not the senior SDET answer
The tool is not the decision. Senior test engineering begins with what failure costs, what evidence is trustworthy and who owns the response.
Architecture
Security requirements that cannot be tested are not finished
A security requirement becomes useful when a team can observe the behavior, test the boundary and know who owns failure.
Staff engineering
Staff engineers change the decisions a team can make
The platform changes. The staff transition does not: your work must improve decisions beyond the feature and beyond your own presence.
Career strategy
The Engineer nobody chases
The most common reason capable engineers stall has nothing to do with code. It is how much coordination work lands on other people after you have finished.
Interviews
A correct Android answer can still fail the interview
Two answers to the same Android question, both correct, scored completely differently. What senior loops are measuring once you clear the knowledge bar.

Career strategy
The two documents that decide your career are written by other people
One gets written after your interview. The other gets written after your offer. You never see either, and that is exactly why they cost you money.
Swift concurrency
Swift concurrency bugs that pass code review
Four Swift concurrency bugs that survive code review at good companies: actor reentrancy, leaked tasks, ignored cancellation, and the onAppear trap. With fixes.
Architecture
Mobile System Design is not backend System Design
Why offline, device constraints, sync, app lifecycle and platform boundaries change the interview and the architecture.
Performance
Why iOS apps feel slow even when the API is fast
A practical look at the client-side bottlenecks that make mobile apps feel slow after the backend has already done its job.
Architecture
How to review a mobile architecture proposal
A practical review framework for mobile architecture decisions: constraints, reversibility, ownership, migration and production proof.
Interviewing
Senior iOS interviews are about risk
The strongest candidates do not just answer the question. They show how they think about production risk, tradeoffs and recovery.
Career growth
Resume bullets for senior iOS Engineers
How to turn mobile engineering work into evidence of scope, judgment and impact without exaggerating.
SwiftUI
SwiftUI vs UIKit: architecture is state ownership
Why production SwiftUI architecture is less about folder names and more about ownership, identity, effects and boundaries.
Staff engineering
Staff iOS Engineer is not Senior Plus
The staff role is not just harder tickets. It is scope, leverage, decision quality and making other engineers more effective.
Swift concurrency
A modern Swift concurrency interview map
A senior interview map for async/await, actors, cancellation, task lifetime, Sendable and the bugs hidden around awaits.
AI
Mobile AI features need product boundaries
How to think about on-device AI, LLM features, privacy, latency, fallback behavior and user trust in mobile apps.
Technical leadership
Tech Lead code review is a system
Good code review is not comment volume. It is a system for quality, ownership, mentoring and risk control.
Freelancing
A freelance mobile architect needs positioning
Why independent mobile architecture work depends on clear problems, scoped offers, proof and delivery boundaries.
