Full-stack Software Developer building SaaS, AI products, and enterprise management systems.
I turn messy business workflows into fast, usable software: CRMs, ERPs, POS systems, dashboards, automation tools, AI assistants, and production web apps.
Portfolio - LinkedIn - GitHub - Email
I work best where product thinking and engineering meet.
- SaaS products with authentication, roles, subscriptions, dashboards, documents, reporting, and admin workflows.
- Enterprise software for operations, sales, inventory, finance, team management, offer generation, and workflow tracking.
- AI-enabled systems using OpenAI, structured outputs, assistants, automation, and business-specific knowledge flows.
- Production web apps with Next.js, React, TypeScript, Prisma, PostgreSQL, MySQL, Supabase, Redis, and Vercel.
- Client-facing platforms that need clean UX, reliable backend logic, SEO, analytics, and maintainable architecture.
I am currently focused on building software for founders and businesses that need real products, not just pretty pages.

Tools and Delivery
Good software should feel calm from the outside and disciplined from the inside.
I care about:
- turning real business operations into clear data models and workflows
- shipping useful MVPs without trapping the product in throwaway code
- designing interfaces that teams can use every day without getting lost
- keeping auth, permissions, files, reports, integrations, and admin flows understandable
- using AI where it improves the product, not where it only makes the pitch sound louder
- Co-founder and CTO at Levant IT Solution.
- Full-stack developer with 5+ years of experience building production web apps and AI-powered systems.
- Built and led development across 10+ client and product projects for businesses in multiple countries.
- Worked on SaaS, enterprise management systems, POS/inventory products, automotive software, education tools, nonprofit platforms, and AI assistants.
I like working with founders and teams who need software that can actually run a business: dashboards, workflows, AI systems, operational tools, SaaS platforms, and products that survive past the first demo.
