Project details
If your development is already underway or even completed, but you want to be confident in the quality, stability, and scalability of your product, our Code Review service is what you need.
We perform a deep and structured analysis of your existing codebase. We focus on architecture, code readability, performance, security, and maintainability. Whether you're working with internal developers, freelancers, or another agency, it's always a good idea to have a second opinion from an independent team with a strong engineering background.
As part of the Code Review phase, you’ll get:
• A detailed written report with comments on code quality, structure, and organization
• Identification of anti-patterns, technical debt, and potential security vulnerabilities
• Suggestions for improvements in naming, modularity, and documentation
• Recommendations for aligning the codebase with industry best practices and your tech stack’s standards
• Consultation call to go over findings and next steps
If you’re looking for a technical partner who will treat your codebase as their own and offer clear, honest feedback, let’s get started.

What can I say? Aleksandr and his team have been with me every step of the way. They understood the project which is complicated, unique and built form scratch. They tested multiple APIs until they found the right one for the project and have been thoughtful throughout the process. They're always communicative and ready to schedule a call to talk through anything that needs to be discussed. I'm looking forward to continue working with them on the next phase. They truly are the best!

🚀 15+ years building iOS, Android, Flutter, and React Native apps
🤖 Specialist in AI integrations, LLM agents, and automation
💼 CTO-level experience leading mobile and SaaS product builds
Hi, I'm Aleksandr Vdovichenko, a senior mobile app developer and AI engineer who helps startups, scale-ups, and product teams ship reliable iOS and Android apps and AI-powered SaaS products.
I work across native iOS development with Swift and SwiftUI, native Android development with Kotlin, and cross-platform mobile development with Flutter and React Native (Expo). On top of that, I integrate modern AI stacks: OpenAI, Claude, Anthropic API, Hugging Face, LLM agents, RAG, and Whisper, so your app does more than display data, it reasons, automates, and adapts.
📱 Mobile App Development I Deliver
Native iOS apps with Swift and SwiftUI for iPhone, iPad, and Mac
Native Android apps with Kotlin for phones and tablets
Cross-platform Flutter and React Native apps for iOS and Android
MVP development for startups, from idea to App Store and Google Play release
App refactors, performance optimization, and stability reviews
Push notifications, deep links, in-app purchases, subscriptions, payments
Bluetooth, Apple Health, HealthKit, Google Fit, camera, AR, and offline-first features
API integration, GraphQL and REST, Firebase, Supabase, and custom backends
🤖 AI & Automation Services
LLM-powered apps with OpenAI, Claude, and Anthropic API
Autonomous AI agents and multi-step reasoning workflows (not just chatbots)
Claude Code development for production AI logic and backend orchestration
AI integrations into existing iOS, Android, and SaaS products
Whisper-based voice features, OCR, computer vision, and pose estimation
AI automation pipelines with n8n, Make, and custom serverless workflows
RAG, embeddings, vector databases, and intelligent search
AI-driven features for fitness, health, fintech, and social apps
⚡ No-Code & Low-Code Speed
For founders who need to validate fast, I combine native skills with modern no-code and low-code stacks:
Bubble for full SaaS platforms
FlutterFlow for cross-platform mobile MVPs
Lovable, Replit, Bolt.new, v0 for rapid prototyping
Webflow for marketing sites and scalable web apps
Adalo, Glide, Airtable for lightweight no-code products
Capacitor and Expo for hybrid app deployment
Supabase, Firebase, and Vercel for backend and hosting
🎯 Industries I Work With
SaaS platforms, fintech and trading apps, health and fitness apps, mental wellness, telemedicine, social and dating apps, e-commerce and marketplaces, food delivery, education, and AI-first products.
✅ How I Work
Clear architecture and tech stack recommendations from day one
Predictable delivery with regular demos and progress reports
Clean, maintainable code your future team can pick up
Focus on App Store and Google Play compliance, performance, and stability
Long-term partnership, ongoing maintenance, and scaling support
If you're planning a new mobile app, an AI-powered SaaS, an MVP, or scaling an existing product, let's discuss your goals and define the right approach.
💌 Send a message and let's build something that ships and scales.
