At 1inch, I worked on high-throughput backend systems in a production DeFi environment, where reliability, latency, and fault isolation mattered as much as feature delivery.

I helped migrate service-to-service communication from NATS to Kafka and gRPC, and integrated distributed observability across logs, metrics, and traces to make production behavior easier to understand and debug.

I was also regularly involved in live incident response, root-cause analysis, and the design, review, testing, and optimization of new backend features and products.

At Token13, I joined on a short contract to design the backend for a non-custodial multi-chain wallet and lead the backend team. Within a four-month engagement, I took ownership of systems spanning Bitcoin, EVM-compatible chains, Tron, and Solana, with a strong emphasis on correctness, reliability, and secure production behavior.

I designed and implemented backend services as well as the mobile SDK layer for Android and iOS, enabling wallets to handle private keys securely, sign transactions, and interact safely with backend APIs.

I integrated multiple blockchain data providers with redundancy and failure handling in mind, so the system could remain reliable and performant despite inconsistent external infrastructure.

At Teavaro, I grew from junior engineer to senior engineer while working on backend systems for real-time customer data and identity infrastructure. Over that time, I took on increasing responsibility across service design, production debugging, performance work, and the long-term maintainability of systems running in production.

I worked on message-driven systems processing around 10,000 events per second using Go, RabbitMQ, Apache Flink, and PostgreSQL. A major part of the work was improving throughput and reducing infrastructure cost through concurrency and architecture changes, while building backend services, APIs, and internal tooling that supported large-scale production data flows.
