The most amazing...
...real-time trading platform I've designed used CQRS and event sourcing, which used Apache Kafka as storage for events and NoSQL databases for projections.
Work Experience
.NET Software Engineer
INVENT.us
- Developed and maintained the platform's back end for digital advisors, using CQRS, event sourcing, and a domain-driven design.
- Analyzed, found, and eliminated bottlenecks on performance-critical parts of the system.
- Developed important framework elements for projections to mongo, Elasticsearch, and SQL.
Software Development Engineer
Amazon.com
- Took ownership of one microservice from start to end, including analyzing business requirements and metrics, choosing the best technology to solve the problem at hand at the lowest cost, and writing supporting documentation.
- Wrote a front-end app using React Redux for an internal tool to query data about order movement.
- Maintained the existing services and performed on-call duties.
C# Architect (remote)
Lykke (via an online freelance agency)
- Focused on adapting Lykke's existing margin trading platform to external customers' needs.
- Implemented a real-time reporting and monitoring service called Big Brother. It observed trading activities of the system via RabbitMQ, pushed messages to the client via TCP sockets, and HTTP API to query past messages and current snapshots.
- Implemented a service called Pump, which was connected to the client's TCP sockets and pushed quotes to our system.
- Implemented a service called Gavel, which did pre-trade control. It gave clients the ability to accept and reject every trade that was about to be created in our system.
- Implemented service for end-of-day processing, which was managing complex workflows.
- Participated in designing and implementing various other microservices.
C# Architect/Team Lead (remote)
Lykke (via an online freelance agency)
- Designed and implemented high-frequency margin trading platform with CQRS and Event Sourcing using Apache Kafka as event store, MongoDB as storage for snapshots of aggregates, Redis/MongoDB/Elasticsearch for projections, ASP.net Core MVC for HTTP endpoints, WAMP for server-to-client communication, and React on the front end side.
- Modeled the domain with the help of BAs..
- Wrote an event sourcing framework, which managed the state of aggregates (by querying snapshot storage and replying to events from Kafka).
- Wrote framework for projections which had the ability to consume events from Kafka from one or multiple sources and form materialized views/push messages to UI (via Crossbar) or to any external client. It used micro-batching to utilize the network or IO properly and to deal with backpressure. It also managed input event offsets.
- Led a team of globally distributed developers, established coding and testing standards and practices, reviewed every pull request, distributed the work, explained to co-workers the business domain and the design of system, and established healthy and friendly relations within the team.
- Designed and participated in implementations of other crucial components including HTTP APIs, end reports, front end, session management, authentication, and more.
C# Engineer (remote)
Lykke (via an online freelance agency)
- Created reporting application. It used background jobs to pull data from multiple sources and form materialized views inside azure table storage.
