Dmitrii P.

👋 Hi, I’m Dmitrii — a backend-focused full-stack developer working with Go, Python, React, and Web3 technologies. I build reliable APIs, data-driven web applications, dashboards, admin systems, and custom platforms. My main focus is backend development, system architecture, integrations, and the business logic that makes products work reliably from end to end. I’m comfortable working on both new products and existing systems. I can contribute to the architecture, develop the backend, build the frontend, create administration tools, integrate external services, and test complete product workflows. I work with both Go and Python, choosing the right technology for the project. I use Go for high-performance services, APIs, and systems where simplicity and efficiency are important. I use Python for backend applications, automation, integrations, data processing, and projects built with frameworks such as FastAPI and Django. On the frontend, I use React to create responsive interfaces that integrate with backend APIs. I also build lightweight HTML-based tools and administration panels when a simple and efficient interface is more appropriate than a full frontend application. I can help with: ✔️ Backend services and REST APIs ✔️ Full-stack web applications ✔️ SaaS products and MVPs ✔️ User accounts, authentication, and dashboards ✔️ Custom admin panels and internal tools ✔️ Database-driven applications ✔️ Third-party API integrations ✔️ Web automation and data-processing workflows ✔️ Web3 and EVM integrations ✔️ Crypto payment and transaction workflows ✔️ RPC communication and blockchain testing environments ✔️ Existing application improvements, debugging, and new features 📌 Backend development: • Go with Chi • Python with FastAPI and Django • RESTful API design • SQL databases, SQLC, and database migrations with Goose • Authentication and authorization • Business logic and service integrations • Asynchronous processing and background workflows • Modular and maintainable application architecture 📌 Frontend development: • React • JavaScript • API-connected interfaces • User dashboards • Forms, tables, modals, and interactive workflows • Responsive web interfaces • Lightweight HTML-based admin tools 📌 Web3 and crypto: • EVM-compatible networks • Web3 application integrations • Crypto transaction processing • RPC communication and testing • Private EVM test environments • Wallet and payment-related workflows If you need a Go or Python backend developer, a full-stack engineer for a web application, or help integrating Web3 functionality into an existing product, feel free to send me a message.
