About Ivan Pinchuk

I build systems that let teams sleep peacefully at night.With 9 years building high-performance backend systems, my approach centers on four principles- Proactive observability — catching issues before users notice- Evolutionary architecture — scaling systems without rewrites- Graceful degradation — maintaining service during partial failures- Secure-by-design thinking — preventing vulnerabilities at architecture levelCareer highlight: designed and maintained game server infrastructure supporting 1M+ daily active users with ~99% uptime, enabling the team to ship features confidently without production incidents.Core expertise: C#/.NET, Redis, SQL, ElasticSearch, ASP.NET Core — used to build systems handling millions of requests daily while maintaining stability under heavy load.Currently expanding into Rust to build even more robust, memory-safe systems.What I\'m looking for: Senior/Staff Software Engineer roles in product-driven companies (gaming, fintech, B2C platforms) where system reliability and team velocity matter.Let\'s connect if you\'re building systems that need to scale gracefully.

   Architected resilient microservices for new game features, applying circuit breaker patterns, gracefuldegradation, and chaos engineering principles to ensure system stability during traffic spikes and partial failures- Identified and eliminated a critical API vulnerability that exposed metadata enabling request tampering,causing high six-figure annual revenue loss from exploits. Redesigned response schema to enforceleast-privilege data exposure, fully mitigating the attack vector and protecting game economy integrity- Eliminated performance bottleneck in stickers/albums service that caused frequent Redis timeouts during peak events, frustrating players and impacting engagement. Redesigned Redis access patterns, integrated RedisJSON for efficient nested data handling, and added in-memory caching — eliminating Redis timeouts under peak load while reducing infrastructure costs by ~40% and improving player satisfaction- Optimized service startup logic, reducing deployment downtime from 10 minutes to 2-3 minutes through database query optimization and lazy-loading of non-critical data. This achieved near-zero-downtime deployments, eliminating the need to schedule releases during low-traffic windows and enabling continuous delivery without user disruption- Optimized critical backend services through strategic caching, query tuning, and Redis optimization —achieving 3-5x performance improvements across multiple endpoints while reducing resourceconsumption, enabling the platform to handle growing traffic without infrastructure scaling- Integrated Redis pipelining and Lua scripting for the configuration service and other critical endpoints,reducing Redis round-trips by ~50% and improving throughput by 3x. This optimization prevented Redisfrom becoming a bottleneck as the user base grew, maintaining sub-100ms response times at peak load.
