🏆 Toptal Certified | 💎 Worked with Fortune 500 Companies
I build production-ready AI systems that integrate seamlessly into real-world applications - not just demos that break under load.
My expertise combines AI integration with 10+ years of system architecture and DevOps, which means the AI solutions I deliver actually work at scale, handle edge cases, and integrate cleanly with your existing infrastructure.
➔Recent AI Projects:
→ MyScribe - AI medical transcription platform (client won Best Startup in Arizona): Built real-time transcription, summarization, and clinical note generation using OpenAI APIs. Handles HIPAA compliance, secure data processing, and scales across multiple healthcare providers.
→ Commercial Co-oP AI Copilot - Added intelligent automation to commercial real estate platform: Deployed AI-powered search, automated listing analysis, and smart recommendations that reduced broker research time by 60%+.
→ Sustainable Business Platform - Implemented AI-driven search and matching algorithms for 3-portal web application with advanced filtering and business discovery features.
➔ What I Specialize In:

2. Technical Proposal - Architecture diagram, timeline, and realistic cost estimate
3. Iterative Development - MVP in 2-3 weeks, then refinement based on real usage
4. Production Support - Deployment, monitoring, and optimization
Most clients start with a system audit (complimentary, no obligation) where I map out exactly which AI capabilities would deliver the biggest business impact for your specific use case.
➔ Tech Stack:
- AI/ML: OpenAI API, Anthropic Claude, RAG systems, Vector databases (Pinecone, Weaviate)

Not just a developer. A technical partner who gets your product shipped — and leaves your team able to own it after I'm done.
I work with founders, CTOs, and product teams building .NET backends that actually scale. From greenfield SaaS to legacy ASP.NET migrations to microservices rewrites — I've done it across Healthcare, Cybersecurity, SaaS, Travel & Hospitality, and EdTech.
🔧 Sound familiar?
• Your SaaS backend wasn't built to grow — and it's showing
• Legacy ASP.NET app drowning in technical debt
• APIs are slow, DB queries are timing out, users are complaining
• You need microservices but don't know where to start
• Cloud costs are climbing with nothing to show for it
🚀 How I work:
Discovery → Architecture → Build → QA → Deploy → Scale
No hand-holding needed. You describe the problem, I own the solution end to end.
💻 Core Stack:
→ Backend: ASP.NET Core, C#, Web API, EF Core, Dapper
→ Frontend: Angular (2–18), React, Next.js, TypeScript
→ Architecture: Clean Architecture, Microservices, CQRS, DDD
→ Database: SQL Server, PostgreSQL, Redis
→ Cloud & DevOps: Azure, AWS, Docker, CI/CD, Hangfire
→ Auth & Security: JWT, OAuth, Identity Server, HIPAA-aware
🎯 I can plug in as:
✅ Senior developer on your existing team
✅ Tech lead owning architecture decisions
✅ Fractional CTO for startups without a technical co-founder
Let's build something that doesn't fall apart at scale. Drop me a message.
