01 — About

From UIKit view controllers
to SwiftUI views.

Twelve years in iOS development, navigating the evolution of the platform — from automotive systems and EVs to fintech and real-time trading.

Maxim Egorov MAXIM · BELGRADE 🇷🇸

The constant across those twelve years has been the same pattern: join a small team, find the part of the codebase that nobody wants to touch, and make it something the team is proud of. Crash rates, build times, latency, hiring — the work changes, the move doesn't.

Today that pattern runs at two levels: the code and the team. When the codebase is healthy, I turn to the people — setting technical strategy, mentoring engineers toward their next level, and raising the hiring bar.

Technical Excellence

Senior expertise in Swift, SwiftUI, and modern iOS architecture, with a track record of delivering performant, scalable applications.

Team Leadership

Experienced in building and leading high-performing development teams with a focus on growth and collaboration.

Engineering Leverage

Uses Claude, Codex, and custom CLI workflows to speed up development, reviews, documentation, and internal tooling — without replacing engineering judgment.

02 — The story so far

Engineer, architect, lead — the complete picture.

A decade told through the products I shipped, the teams I built, and the kinds of problems I'd never want to solve any other way.

B2Broker

Senior iOS Engineer → iOS Team Lead
Feb 2024 — Present · 2+ years

Joined to build trading components. Five months later I was running the team.

B2Broker is a global liquidity and technology provider — $700B+ annual trading volume, 3.5M+ trading accounts across their infrastructure. Problem: large real-time market-data UI in SwiftUI. Constraint: frequent updates, expensive diffing, and latency-sensitive trading flows. Decision: isolate state, keep rendering granular, and throttle updates where precision allowed it. Result: stable order-book and market screens across 3,000+ instruments. Today I own architecture, hiring, and the technical strategy for that platform.

  • Designed a SwiftUI architecture for real-time market-data streaming across 3,000+ instruments, optimizing diffing, state updates, and rendering under sub-second latency constraints.
  • Shipped real-time order book + market data streaming under tight latency budgets.
  • Drove cross-functional iOS architecture decisions across mobile, backend, QA, and product for latency-sensitive trading flows.
  • Defined iOS architecture standards and review practices for state isolation, rendering boundaries, and feature delivery.
  • Built and led a team of 6 iOS engineers — hiring, code review, 1:1s, and technical growth.

Charge Cars

Senior iOS Engineer

Sole iOS engineer on the project: built the entire companion app for an electric sports car inspired by the 1967 Mustang Fastback.

Charge Cars rebodies classic Mustangs as fully electric, hand-built EVs. There was no iOS team — there was me. From architecture to UI to the BLE handshake with the car's onboard systems, every line of Swift was mine. The brief: the app had to feel as premium as the car.

  • Remote control: locking/unlocking, climate pre-conditioning, real-time charging status.
  • Secure REST + BLE communication with the vehicle's onboard systems.
  • GPS-backed find-my-car and trip monitoring, resilient to spotty connectivity.
  • Built all UI components from scratch — matched the car's premium aesthetic throughout.

Companion in your pocket.

SwiftUI dashboard tuned to the car's tone of voice — monochrome, mechanical, restrained. Battery, lock, frunk, mirrors, climate — all live, all over BLE + REST.

02

One language, two surfaces.

The car has its own UI — twin displays, mechanical pillar of switches. The phone app had to feel like a third surface of the same product, not a generic companion. Type, density, motion: all tuned to match.

Arrival

iOS Engineer → Senior Software Engineer

Four years of iOS for purpose-built electric vans, manufactured in low-footprint microfactories.

Arrival designed commercial EVs from scratch — battery, body, software, everything. I owned two production iOS apps end-to-end: a driver/operator companion for live telemetry and remote control, and a key-and-access app for NFC unlock. The work crossed GraphQL contracts, Protobuf telemetry, BLE pairing, and a strict SwiftUI design system.

  • Migrated client–server from REST to Apollo GraphQL with generated, type-safe contracts.
  • Built live telemetry pipelines (Combine + Protobuf) for battery, location, and accelerometer streams.
  • Modularised the codebase into 12+ Swift packages so feature teams could ship independently.
  • Drove unit & UI test coverage past 95% on owned modules; defined the testing playbook.
  • Researched NFC tags for door access; shipped private XCFrameworks for internal distribution.

At-a-glance vehicle status — charge, range, doors, climate. Driven by a live Protobuf telemetry stream through Combine publishers into SwiftUI.

Battery & charging

Deep-dive into the pack: state of charge, charging rate, time-to-full. Charts hand-rolled in SwiftUI to keep dependencies thin and motion exact.

Key & access

NFC unlock paired over BLE. Fleet managers grant or revoke driver access remotely. The handshake had to feel instant, with UI feedback kept inside tight interaction budgets.

Cryptopay

iOS Developer → Senior iOS Engineer

Joined to ship features on a crypto wallet. Stayed to lead the team and rewrite it in Swift.

Crypto-payments app with a sizable Objective-C codebase. The interesting work happened on the side: a year of patient Swift migration in parallel with feature shipping. By the time I left, 70% of the codebase had moved over and the iOS team was running on a healthier foundation.

  • Pulled crash-free sessions above 96% — was hovering in the low 80s when I joined.
  • Shipped iPad and Apple Watch versions of the app alongside the main iPhone build.
  • Migrated 70% of the Objective-C codebase to Swift without a feature freeze.
  • Took over hiring, code review, and project management for the iOS team.

Where it all started.

  • Aug 2016 — May 2017
    Embria · iOS Developer

    Built features on OlympTrade — a retail trading and investment platform with millions of users. First big task: a full UIKit redesign delivered in two months. Then a seasonal mini-game (SpriteKit + CoreAnimation) built around the Christmas cycle that pushed retention past 20%. First real lesson in consumer fintech: crash budgets, App Store review pressure, and users who notice every dropped frame.

  • May 2014 — Aug 2016
    Game Insight · iOS Developer

    Two years at one of Russia's larger mobile game studios, shipping cocos2d-based titles. Most of the work lived at the rendering layer — writing shaders, optimising draw calls on constrained hardware, and making animations feel smooth on the device range of 2014–2016. Also integrated a stack of third-party SDKs (analytics, ads, social) and worked closely with QA to hit game-designer specs to the pixel.

  • Sep 2013 — May 2014
    Murmansk State Technical University · System Administration Specialist

    Started here while still a student — maintaining the university's computer network, diagnosing hardware failures, and setting up workstations for labs and staff. Unglamorous work, but it taught me how systems actually fail: that every timeout has a physical cause somewhere, and that patience with a terminal window is a transferable skill.
