Waleed R.
Senior .NET Developer | ASP.NET Core, C#, Azure, Angular & React
Need a senior full-stack developer to build, fix, modernize, or scale your application? I’m a software engineer with 8+ years of experience delivering SaaS platforms, enterprise applications, and business-critical systems. My strongest foundation is C#, ASP.NET Core, .NET, Angular, React, SQL Server, and Azure, but I work across the stack and choose technologies based on what your product actually needs. I can take your project from idea to production, improve an existing application, or turn an AI-built prototype into software that’s ready for real users. WHAT I CAN HELP YOU WITH • Full-stack & backend development: ASP.NET Core, C#, MVC, REST APIs, Angular, React, Next.js, Node.js, TypeScript, SQL Server, PostgreSQL, and MongoDB. • SaaS & MVP development: Multi-tenant platforms, subscriptions, billing, authentication, RBAC, dashboards, customer portals, and third-party integrations. • Code reviews & application rescue: Audit code quality and architecture, diagnose bugs, address security and performance risks, reduce technical debt, and improve maintainability. • AI-built MVPs: Built something with Lovable, Bolt, Replit, Claude, Cursor, or ChatGPT? Great start. I can assess what works, fix weak spots, add missing functionality, and prepare it for production, without recommending a rewrite unless it makes sense. • Legacy modernization: ASP.NET MVC and .NET Framework maintenance, migrations, API upgrades, database optimization, and cloud adoption. • AI & automation: LLM API integrations, document processing, OCR, semantic search, n8n, Make, and custom workflows. • Cloud & DevOps: Azure App Service, Functions, Azure SQL, Docker, CI/CD, GitHub Actions, Azure DevOps, deployments, and monitoring. INDUSTRIES I’VE WORKED IN • Healthcare & HealthTech: Telemedicine, patient portals, provider management, EHR integrations, and analytics. • Insurance & InsurTech: Provider data, insurance workflows, reporting, and enterprise integrations. • FinTech & lending: Underwriting systems, payment integrations, document processing, and financial workflows. • SaaS & B2B: Subscription platforms, CRM, commission management, and operations software. • Logistics & fleet: GPS tracking, geofencing, maps, dashboards, and fleet operations. • Real estate & PropTech: Property management, rentals, leases, payments, and maintenance. • EdTech: Learning platforms, assessments, adaptive learning, and dashboards. • HRTech & payroll: Benefits administration, payroll reporting, and workforce workflows. The same engineering capabilities also apply to e-commerce, manufacturing, supply chain, LegalTech, and other emerging digital products. I learn the business workflow first rather than assuming every industry needs the same solution. ONE TECHNICAL PARTNER — COMPLETE SDLC I’ve independently managed projects through the full software development lifecycle and can take responsibility for: 1. Discovery, research, requirements, and feasibility 2. Architecture, database design, planning, and documentation 3. Frontend, backend, APIs, integrations, and implementation 4. Code review, debugging, automated testing, and QA 5. Infrastructure, CI/CD, DevOps, deployment, and monitoring 6. Maintenance, performance improvements, and new features For a suitably scoped project, you can work with one accountable engineer rather than coordinating separate specialists at every stage. I can also collaborate with or lead your existing team. AI-ASSISTED SPEED, ENGINEER-LED QUALITY I use Claude Code, Cursor, and other professional development tools to accelerate research, coding, testing, debugging, and documentation. I still review the output, verify architecture and security decisions, and test the result. AI is a productivity tool, not a substitute for engineering judgment. I respect project confidentiality and your requirements for AI tool usage. LET’S TALK ABOUT YOUR PROJECT • Starting from an idea? Tell me who the users are and what you want to build. I can help plan the architecture and development path. • Have an AI-generated MVP? Share what works and what’s broken. I can assess whether to fix, refactor, or rebuild. • Dealing with a legacy system or persistent bugs? Describe the stack and biggest pain point. I’ll help identify practical next steps. • Need end-to-end ownership? Share your scope, timeline, and desired outcome. I can handle the technical delivery from research to launch. Send me a message with: 1- what you’re building? 2- your current challenge? 3- your ideal outcome. You don’t need a perfect specification to get started.
