Hire the Best C++ Programmers & Developers
in Israel

Microsoft-certified senior developer (MCAD .NET) with 20+ years building and maintaining production web systems on the Microsoft stack. I'm the developer you call when a critical system is written in something most people won't touch — Classic ASP, legacy VB.NET, or aging ASP.NET — and it needs to keep running, get fixed, or be carefully modernized without breaking the business that depends on it. What I do best: Legacy rescue & modernization — maintain, fix, and gradually modernize legacy ASP.NET, Classic ASP, and VB.NET applications without downtime SQL Server beyond the basics — performance tuning, deadlock resolution, replication, high-availability and disaster-recovery setups Third-party API integrations in C# / ASP.NET — payment gateways (Stripe), OAuth/OIDC and single sign-on (Auth0, Azure AD / Entra ID), REST and WebSocket data feeds Data export & system integration — moving data cleanly between systems, including exports from Azure and school management platforms Custom web solutions from scratch to production — membership and visitor-management systems, e-commerce, and booking/reservation tools I've done a fair amount of work in the education sector — school management systems including bus reservations, ticketing, and facility rentals — so if you're in that domain, I already understand the problems. Currently a full-time senior developer at a UK software company; I take on select small-to-mid projects alongside that. Clean, working code, clear communication during UK hours, and I don't disappear. If you've got a system nobody else wants to touch — or you need it done right the first time — let's talk.
