Backend-focused Software Engineer with deep experience designing and scaling high-load B2C SaaS platforms, distributed systems, and modern cloud-native architectures. I specialize in building reliable backend infrastructure that supports rapid product growth and high traffic. One of my core achievements was leading the transformation of a large Python monolith into a scalable Go-based microservice ecosystem. The platform leveraged: Go for high-performance services NATS, RabbitMQ and Kafka for asynchronous communication gRPC for efficient internal service interaction PostgreSQL with database-per-service architecture Redis for caching and lightweight task processing S3 for scalable media storage Kubernetes migration from Docker Swarm to improve scalability, resilience, and deployment automation Beyond development, I focus on engineering quality and long-term maintainability: Scalable architecture design Performance optimization and bottleneck analysis Observability and reliability practices Technical planning and solution architecture Translating business requirements into efficient technical solutions I also bring strong outsourcing and product development experience across multiple industries. In these environments, I helped teams significantly improve development processes by introducing: - Code review culture - CI/CD pipelines - SOLID and GRASP principles - Clean Architecture and Domain-Driven Design (DDD) - Shared component libraries and reusable platform solutions Additionally, I contributed to internal tooling and platform engineering, including participation in developing a builder based on Rspack. I work effectively both independently and within distributed international teams. My priority is always delivering scalable, maintainable, and business-oriented solutions — not just writing code. Core stack: - Go (Golang) - Python - PostgreSQL - Redis - RabbitMQ / NATS / Kafka - gRPC - Docker / Kubernetes - AWS / S3 - Microservices Architecture - CI/CD - Distributed Systems - High-Load Systems - Clean Architecture / DDD Available for: - Backend architecture & development - High-load system design - Microservices migration - Performance optimization - Infrastructure modernization - Technical leadership & consulting

Building mobile apps is art for me. I build products people can actually use, trust, and pay for. I help founders turn AI app ideas into clean, useful, revenue-ready mobile products — from MVP planning to App Store and Google Play Store launch. ✦ Want to work with an app builder who thinks like a founder, designs like a product manager, and builds like a developer? ✸ I’ve built multiple startup-style apps, including Piko AI, Lifelink AI, DayDairy, and PriceWise AI — across AI, health, journaling, productivity, grocery tracking, news, live streaming, and community services. ✦ I also have 2 live iOS apps on the App Store, including one Swift app and one React Native app, with Google Play launch in progress. ✦ Good Fit Clients ✸ You have an app idea but no technical team ✦ You need an AI-powered MVP built clearly and professionally ✸ You want iOS, Android, App Store, or Play Store support ✦ You need someone who can think about product, UX, backend, AI, and launch — not just write code ✸ You care about clean design, real users, and long-term improvement ✸ Client Struggles I Solve ✦ “I have an idea, but I don’t know where to start.” ✸ “My app flow feels confusing.” ✦ “The developer built features, but the product doesn’t feel premium.” ✸ “AI integration, backend, payments, and App Store submission feel overwhelming.” ✦ “I need someone who can fix bugs, simplify the system, and guide the launch.” ✦ What You Get Working With Me ✸ Clear MVP planning before development ✦ Premium mobile UI/UX structure ✸ AI features using OpenAI API, Claude API, assistants, and chatbots ✦ React Native/Expo, Swift, Supabase, Firebase, RevenueCat ✸ App Store and Google Play preparation ✦ Clean product thinking, real testing, bug fixing, and launch support ✸ My Experience I’ve failed, tested, rebuilt, fixed, and learned how real app systems work — not only the beautiful side, but also the messy parts: bugs, backend issues, AI integration problems, payment setup, App Store rejection, user confusion, and product mistakes. That experience helps me build apps that are not only beautiful — but usable, clear, and ready for real people. ✦ Sound Like a Fit? Message me if you want an AI mobile app developer / AI app builder who can help you turn your idea into a clean MVP, launch it, and improve it with real user feedback.
