Work Experience

C# (.NET) Software Architect

2017 - PRESENT
Lykke Inc
  • Contributed to margin trading services architecture design and development of essential parts.
  • Orchestrated team member work for 2-6 developers.
  • Took part in company software infrastructure gardening: created BrokerBase library to simplify and standardise brokers creation (works with RabbitMQ + Azure Tables or MSSQL, used in >20 services), optimized CI flow to automate preparation of service releases, empowered the service health control with a custom metrics feature to gather additional data at runtime.
  • Designed and implemented margin trading risk control from a prototype to a fully-functional solution: analyzing trading platform's accounts/positions/orders/quotes state (>1,000/sec), making real-time decisions and performing automated actions.
  • Designed and implemented aggregated hedging to increase/reduce hedging positions on partner crypto exchanges automatically. It was really inspiring to make the design of such a big integration project from scratch.
  • Forked and customized a well-proven margin trading core for a large bank conglomerate: created integration layer to the bank's infrastructure (accounting, reporting, settings services, etc) and newly created mobile and web apps. It took quite a time to make performance optimizations for bank's tight requirements: 10k orders open with 15,000/sec incoming quotes. The hard thing was to rebuild from scratch obsolete services without any documentation. At the same time, it was an interesting experience to work with a big distributed team of >40 members.
