I had the pleasure of hiring and working with Maxim to build our app - Vibes. He came in at the best time possible when we were going to transition from a telegram mini app to a mobile app. His speed and ownership ethos impressed me and within a month we had an app ready to go live on global app stores. Beyond his technical work, what impressed me was his dedication and passion towards building a superior product for…
G'day, mate!
I'm Maxim Spiridonov
Mobile & Web Engineer — React Native, iOS (Swift), React/Next.js.
I build production apps end-to-end: React Native or fully native iOS, plus complex web with React/Next.js and Node.js. Recently: a cross-platform trading app with Solana wallet/transaction flows, a Telegram Web App migrated into a full mobile app, launching AI tools and agents. I move fast, keep code clean, and deliver stable releases.
What I do
I’m a mobile & web engineer who ships products end-to-end — React Native or fully native iOS (Swift) on mobile, and React/Next.js + Node.js on the web.
I’ve led builds from 0→1 to scale: a cross-platform trading app with Solana wallet/transaction flows, NFT tooling that moved real business metrics, analytics & data-viz platforms, and high-polish consumer features (video, AR, deep links, push).
I work fast, keep code clean, and own outcomes — from architecture and CI/CD to hands-on delivery. I regularly tear down products ethically (reverse-engineering, perf audits, DX reviews) to understand how they work inside and make ours better.
I’ve collaborated with rock-star engineers in high-pressure environments and learned to adapt process and architecture through pivots. I started back when table-based layouts were still a thing and Objective-C ruled iOS — that depth helps me solve hard problems quickly and leave codebases better than I found them.
React Native
- iOS & Android from a single codebase (Expo/CLI)
- Store-ready UX, performance & stability
- Secure auth, push, deep links, in-app updates
- Architecture & system design for scalable mobile apps
Native iOS (Swift)
- Swift/SwiftUI/UIKit
- Deep links, push, payments, caching & performance
- CI/CD & release pipelines (Fastlane, GitHub Actions, TestFlight)
- Architecture & system design (modularization, SwiftUI/UIKit patterns)
Web Platforms
- React/Vue/Next.js, TypeScript, Node.js,SSR, performance, CI/CD
- From 0→1 MVP to scalable production
- AI tools & agents (LLM): automation, prompts, evals, guardrails
- Architecture & system design (monorepos, service boundaries, scalability)
