I'm Alex Kiselov, a senior iOS consultant who helps teams stabilize, modularize, and modernize complex apps when releases are risky, architecture is slowing delivery, and certain parts of the app feel too dangerous to touch.
Based in Pennsylvania, USA · Available remotely
Previously embedded with engineering teams at large-scale healthcare and retail organizations serving millions of users.
I work best with teams dealing with production risk, legacy architecture, and pressure to move faster without destabilizing the app.
Checkout, auth, account, pharmacy, or other flows where regressions are expensive and release confidence matters.
Apps that became hard to reason about, hard to change, and dependent on brittle internal coupling.
When the app needs modernization, but a full rebuild would be too risky, too slow, or politically unrealistic.
Focused support for teams that need safer releases, strong new feature delivery, cleaner architecture, and practical modernization.
Reduce release risk in code areas the team avoids touching. Untangle risky dependencies, fix hidden failure points, and make core flows safer to change.
Build production-ready iOS features in complex existing apps without adding more fragility, hidden coupling, or architectural debt.
Break monoliths into clearer boundaries that improve maintainability, ownership, and long-term development speed without forcing a disruptive rewrite.
Guide practical migrations to SwiftUI, modern concurrency, and cleaner architecture with a risk-aware approach built for production systems.
Review your iOS architecture, identify technical bottlenecks, and give you a clear plan for what to fix first, what to defer, and how to move safely.
Support product and engineering decisions with senior-level judgment around architecture, delivery tradeoffs, and how to move faster without creating long-term problems.
Selected examples of the kinds of environments and problems I’ve worked in.
Worked inside large-scale healthcare mobile systems used by millions of users, where reliability, compliance, and release safety were non-negotiable.
Helped untangle difficult dependency structures in older code so teams could move faster with less fear of breaking unrelated parts of the app.
Contributed to modularization, modernization, and delivery strategy in environments where multiple teams, legacy systems, and production constraints all had to be respected.
Flexible ways to work together depending on your team’s needs and constraints.
I join your team as a senior IC and work directly in the codebase. Best when you need immediate execution in a live product environment.
A focused engagement to audit the codebase, map risks, and define a practical modernization or modularization plan with clear next steps.
Ongoing access for architecture review, technical judgment, and senior guidance when your team needs experience but not another full-time hire.
I’m a Senior iOS Engineer focused on large-scale production apps, especially the systems teams are hesitant to touch because the business impact is high and the architecture has become hard to move safely.
Most of my value comes from helping teams regain control over complexity: stabilizing risky areas, improving architecture without drama, and making the codebase easier to evolve over time.
If your app is slowing down because of legacy structure, release anxiety, or too much hidden coupling, that’s the kind of problem I’m built for.
Core technologies and areas I work with in real production environments.
Send me a short note about the codebase, the release risk, or the architecture problem you’re dealing with. I’ll tell you whether I can help and what I’d look at first.
