About Anton

Full-Stack Developer specializing in creating digital solutions that help companies save time, reduce errors, automate processes, improve internal operations, and launch web products faster and more efficiently.

I help turn business problems into practical software.

I work across the entire product cycle: business process analysis, requirements definition, technical proposal, architecture design, frontend and backend development, testing, deployment, and continuous improvement. I can work autonomously from idea to production, or integrate into a team to improve existing products.

I can help with developing web applications, MVPs, and SaaS platforms; automating manual processes, documents, Excel, PDF, and structured data; creating internal tools for operations, sales, support, and administration; customer portals, admin panels, and business dashboards; integrating APIs, CRMs, databases, payments, and external services; data processing, reporting, visualization, and information validation.

I also develop systems with OCR, data extraction, document classification, and analysis, as well as AI-based functionalities: assistants, chatbots, AI agents, automation with LLMs, text/document analysis, RAG, and internal knowledge tools.

I have experience in backend API design, databases, authentication, roles, jobs, queues, logging, monitoring, production infrastructure, refactoring, and maintenance of existing systems.

I also have experience and interest in blockchain/Web3: wallets, smart contracts, transactions, blockchain events, crypto platforms, and financial dashboards.

Main stack: React, Next.js, TypeScript, Node.js, NestJS, PHP, Laravel, PostgreSQL, MySQL, MongoDB, Prisma, Redis, Docker, Nginx, REST APIs, WebSocket, Git, CI/CD, Tailwind CSS, OpenAI API, LLMs, OCR, automation, and SaaS systems.
