About Sachin Pandhare

Electronic Trading Systems.Majorly worked on building and maintaining the core stateful modules of OMS which manages the state of the order, positions, orchestrate order routing, client application queries related to orders, fills, audit etc, recovery and have very strict availability, reliability and performance requirements.Core work: • Design and development of electronic trading systems (low latency, high throughput, fault tolerant). • Focus on scalability, availability, maintainability, and safety of systems. • Strong background in data structures, caching, and performance optimization.Skills: • C++, Modern C++(STL/Boost), Python.(Learning Zig, Rust, Go) • Deep expertise in Core C++ and language internals — value/reference and move semantics, smart pointers, memory model, OOP, error handling. • TCP/IP networking, Linux internals, memory management. • Software system design, architectures, object-oriented design, state machines. • Profiling, bottleneck analysis, optimization, memory safety.Domain experience: • Capital markets: US, Europe, HK, Taiwan, ChinaConnect • Major OMS contributions:• Built middle office system and OMS from scratch.• Implemented trade bookings matching engine.• Developed core order manager and charge engines (EXEC, BLOCK, ALLOC).• Designed in-memory DB and caching with lazy loading + write-through for latency improvement.• Implemented fail-over using state machine replication.• Designed, developed, and tested multiple OMS components.Additional responsibilities: • Performance tuning, profiling, and debugging. • Fixing system security and memory safety issues. • Building FIX-protocol based systems. • Production support and issue resolution. • Collaboration with business and IT stakeholders across Front and Middle Office to define, design, and implement enhancements and new features.C++17/20, low latency, Linux, trading systems, concurrency, multithreading, design patterns.
