Kamran H.

I help B2B founders stabilize inherited codebases, eliminate system downtime, and modernise legacy systems without breaking live production environments. With 28+ years of hands-on experience directing engineering teams and architecting high-throughput production software, I operate at the intersection of executive technical strategy and core backend execution. Whether you need a Fractional CTO to audit an existing platform or a veteran Senior C# .NET Solutions Architect to safely rescue an enterprise ecosystem, I provide the strategic oversight and technical governance your business demands. Three ways we can collaborate: 1. Fractional CTO Retainer: For platforms that have outgrown their current engineering structure or lack senior oversight. I step in to run your vendors, establish clean coding standards, audit development quality, and align your architectural roadmap with business goals. 2. Technical Debt & Uptime Diagnosis: A fixed-price, 2-week deep-dive system audit for applications facing performance bottlenecks or persistent downtime. You receive a clear, risk-mapped technical blueprint showing what is broken, security vulnerabilities, and an honest build-vs-repair roadmap. 3. SaaS Product Architecture: End-to-end design and database modeling for high-scale, multi-tenant applications. I specialize in complex financial pipelines, webhook reconciliation, and secure infrastructure deployment. Core Production Expertise: • Modernisation & Architecture Rescue: Systematically migrating monolithic .NET Framework, ASP.NET Web Forms, WCF, and legacy SOAP systems over to cloud-optimized, high-performance modern .NET Core ecosystems. • Financial Workflows & Marketplace Infrastructure: Designing multi-tenant Stripe Connect integrations covering split payouts, automated vendor onboarding/KYC, dynamic platform fees, and secure, signed, idempotent webhook reconciliation pipelines. • Performance Engineering: Diagnosing granular database bottlenecks, tuning high-throughput SQL Server architectures, optimizing slow queries, and deploying robust production observability tools. • Strategic Technical Leadership: Transitioning engineering teams to modern Agile frameworks, establishing pull-request workflows, setting release cadences, and mentoring cross-functional developers. I work best with non-technical founders and enterprise stakeholders who realize the stability of their product framework directly impacts their bottom line. If your platform is stuck, facing scale limits, or suffering from constant engineering friction, let's skip the discovery decks. Message me with your current stack bottlenecks, and let's map out a stable, predictable technical path forward.
