What I'm looking for

Seeking full-time remote B2B contracts as a senior backend, full-stack or ERP engineer. 13+ years of experience delivering business software and integrations. Registered sole proprietorship in Türkiye; direct invoicing to international clients. Minimum B2B contract value: USD 24,000/year. Also open to relocation with employer visa sponsorship.

I am a Senior Software Engineer with 13+ years of experience, seeking full-time remote B2B contracts with international teams. I build enterprise ERP platforms, business web applications, SaaS backends and system integrations.

I operate a registered sole proprietorship in Türkiye and can invoice international clients directly under B2B services contracts. I offer one point of responsibility across backend, frontend, integrations and delivery, helping simplify coordination. Engagement terms are subject to applicable requirements and mutual agreement.

At Smart Servis, I spent nearly 11 years as the sole developer responsible for an ASP/MySQL-based ERP: requirements, development, integrations, testing, Linux operations, deployments and backups. Integrations included business partners, public-sector services, SMS providers and bank virtual POS systems.

Recent experience includes C#/.NET Core and Microsoft SQL Server backend maintenance at Asis Elektronik, and PHP development with Laravel and CodeIgniter. My full-stack work also includes React, JavaScript, HTML/CSS, SQL and REST APIs. I choose technologies to suit business needs and am open to learning additional web stacks.

In December 2025, I established Liyamour and independently completed three products, owning requirements, architecture, backend/frontend implementation, integrations and deployment:

• Liyamour ERP: finance, customers, inventory, HR and field service workflows, with role- and company-based access, approvals and audit logs.

• Liyamour CMS: multilingual publishing, visual editing, reusable templates, media management, SEO, visitor analytics and backup/rollback.

• MiniMenu (Liyamour QR Code Menu): mobile-first, multilingual QR menus with an admin panel for categories, products, prices, photos and ingredient/allergen information.

Product descriptions and screenshots (Turkish/English): https://www.liyamour.com/products

Core product development is complete; current involvement is licensing/sales and occasional support. I am fully available for a full-time engagement or long-term contract.

I use AI coding tools to accelerate implementation, debugging and refactoring, validating results through engineering judgment, code review and testing. I retain responsibility for architecture, code quality, security considerations and delivery.

My priority is full-time remote B2B work. Minimum contract value: USD 24,000/year. Also open to relocation with employer visa sponsorship where required.
