Reliable web and mobile apps for startups and product companiesAlexey Sobolev
I’m here to help you stop guessing what to build and give you a step-by-step plan. Instead of just advice, I help you plan, architect, and ship .NET/React/SaaS products so you see real progress. Whether you’re starting from a prototype or stuck scaling, I’ll provide a clear foundation to launch, grow, and hand off to your team, keeping your SaaS roadmap, .NET services, and React UI aligned.
I build SaaS platforms that raised $1B+, reached 450,000+ users, and shipped products featured on the Inc. 5000®.
What's included
SaaS & Web App Development
I build MVPs and scale SaaS platforms using .NET, React, C#, Python/FastAPI, PostgreSQL/MSSQL.
Backend & APIs
Reliable and secure server-side solutions that handle operations efficiently, even as demands increase.
.NET/C#, Python/FastAPI, REST/GraphQL, Entity Framework, PostgreSQL, MSSQL, MongoDB, WebRTC when real-time is required.
Frontend Engineering
I use React UI and React/Next.js for dashboards and portals, TypeScript, Vite, and Blazor when needed.
Mobile App Development
I use .NET MAUI for cross-platform, Swift for native iOS, and reuse your APIs across mobile and web.
Payments & Integrations
Stripe for subscriptions and SaaS billing, PayPal, HubSpot, ActiveCampaign, Microsoft Dynamics 365, Twilio, WhatsApp, Shopify, WooCommerce, Zapier, ChatGPT/OpenAI.
Product Partnership
I will help you grow your team as the product scales. Research, documentation, QA, plan roadmaps, long-term support
