Looking for a 𝐬𝐞𝐧𝐢𝐨𝐫-𝐥𝐞𝐯𝐞𝐥 full-stack engineer who can take your product from concept to launch - including backend, frontend, infrastructure, deployment, and security?

I offer:

⬛ FREE QA, bug fixing & post-launch support;

⬛ Full-cycle product development (architecture, planning, coding, deployment, optimization, maintenance);

⬛ Enterprise-grade API development & third-party integrations;

⬛ SaaS, E-commerce & custom business systems (scalable, high-load architectures using ASP.NET Core, Web API, and modern frontend frameworks);

⬛ Real-Time Applications (live dashboards, notifications, WebSocket integrations, automation systems);

⬛ Linux Server Administration & Infrastructure (Ubuntu, VPS setup, Nginx, reverse proxies, SSL, process management, server hardening);

⬛ Advanced Networking & Secure Infrastructure (WireGuard VPN deployment, secure tunneling, self-hosted remote access systems, encrypted server environments);

⬛ DevOps & CI/CD (Docker, Docker Compose, GitHub Actions, Azure DevOps, deployment automation, monitoring, production optimization);

⬛ Security-First Development (JWT, authentication systems, role-based access, encrypted environments, secure API architecture);

I’m a Full-Stack Developer & Infrastructure Engineer providing 𝐞𝐧𝐝-𝐭𝐨-𝐞𝐧𝐝 product delivery — from 𝐢𝐝𝐞𝐚 𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐢𝐨𝐧 and system architecture to deployment, scaling, and long-term maintenance.

My expertise spans ASP.NET Core, C#, Linux infrastructure, TypeScript, Svelte/SvelteKit, DevOps, and cloud environments. I specialize in building 𝐫𝐨𝐛𝐮𝐬𝐭, 𝐬𝐞𝐜𝐮𝐫𝐞, and 𝐦𝐚𝐢𝐧𝐭𝐚𝐢𝐧𝐚𝐛𝐥𝐞 systems that solve real business problems - whether that means launching a SaaS platform, optimizing business automation, deploying secure VPS infrastructure, or engineering custom enterprise tools.

I combine software engineering with infrastructure thinking - meaning I don’t just build apps, I build systems that last.

🛠 Tech Expertise:

⬛ Backend: ASP.NET Core, ASP.NET Web API, Entity Framework Core, .NET Framework, ASP.NET MVC, Razor Pages, Blazor, Clean Architecture;

⬛ Frontend: Svelte, SvelteKit, JavaScript, TypeScript, Tailwind CSS, Bootstrap, TanStack Query, REST integrations;

⬛ Databases: PostgreSQL, SQL Server, MySQL, MongoDB, SQLite, Redis;

⬛ Linux & Infrastructure: Ubuntu Server, Nginx, VPS deployment, SSL, systemd, reverse proxy, server security, LUKS disk encryption;

⬛ Networking: WireGuard VPN, secure tunnels, remote access architecture, private networking;

⬛ DevOps & Cloud: Docker, Docker Compose, GitHub Actions, Azure DevOps, AWS, deployment pipelines, CI/CD automation;

I focus on:
