What I'm looking for

I’m looking for a role where I can own discovery-to-delivery requirements, design scalable system integrations for high-load products, and partner with engineering and stakeholders to reduce risk, improve adoption, and optimize costs using Agile/Lean practices.

I’m a Senior Business Systems Analyst with 7 years delivering scalable fintech and banking platforms across trading/liquidity, remote corporate banking, and high-load government/enterprise systems. I combine analytical rigor (Master’s in Physics) with end-to-end SDLC traceability to translate business needs into clear epics, user stories, and acceptance criteria.

In my current role, I optimized liquidity quality by integrating 10+ liquidity providers via FIX and REST APIs, supporting up to $450M monthly trading volume and scaling up to 1k RPS. I’ve also lowered churn from 60% to 9% through structured risk and root-cause analysis, improved onboarding time up to 40%, and reduced infrastructure spend up to 13% YoY by replacing external components with an internal integration hub.

I’m strong in discovery and shaping solutions: current/future state, process mapping (BPMN/UML), gap analysis, and aligning stakeholders on roadmap, dependencies, and releases. I work comfortably at the technical design level—APIs (REST/gRPC/WebSocket), FIX/SOAP, SQL/data mapping, and system integration—so requirements stay consistent from design to delivery to monitoring.

I lead product discovery and delivery for trading workflows, including guiding a development team of 6 and turning complex business logic into scalable system design. I also use Generative AI/LLMs (Claude/ChatGPT/Gemini) to systematically identify edge cases and validate solutions, while continuously improving workflow efficiency and quality through Agile/Lean (Scrum, Kanban, SAFe 6.0) practices.
