You need software that works on day one and keeps working as you grow built by someone who understands your business, not just the code.

I'm Umar, a U.S.-based senior engineer in North Carolina. I personally own every project from architecture to deployment: one point of contact, no hand-offs, no surprises.

𝗪𝗵𝗮𝘁 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝗵𝗶𝗿𝗲 𝗺𝗲 𝗳𝗼𝗿:

• SaaS and web applications React, Next.js, Node.js, TypeScript, Python and PostgreSQL, with Stripe subscriptions, multi-tenant architecture, dashboards and admin panels

• AI development AI agents, AI chatbots, LLM integration with OpenAI and Claude, RAG pipelines, vector search and document AI built into real workflows

• Taking AI-built prototypes to production your app started in Lovable, Bolt, Cursor or Replit and now needs auth, security, payments, testing and real infrastructure

• .NET and enterprise systems ASP.NET Core, C#, Azure, and modernizing legacy .NET applications without breaking what already works

• API development and integration REST, GraphQL, webhooks, OAuth, Twilio, Google Maps, CRM and payment gateway integrations

• Mobile apps React Native for iOS and Android

• Cloud and DevOps AWS, Azure, Docker and CI/CD

I work best with founders and teams who need a senior engineer to own the technical side, whether that's building an MVP the right way or scaling a product that's outgrowing its first version.

If that's where you are, send me a message with what you're building and I'll reply with how I'd approach it.
