Vyacheslav D.

**Senior Backend & Platform Engineer | Java • Kafka • AWS • Terraform** 20+ years building high-throughput, fault-tolerant backend systems for fintech and regulated industries. I design and ship production platforms that scale — Kafka/Confluent pipelines processing 100M+ events per day, zero-downtime migrations across 10+ environments, and APIs delivering 30–40% performance gains. **Core skills:** - Backend: Java 17 / Spring Boot microservices, REST APIs, event-driven architecture - Streaming: Apache Kafka, Confluent Cloud, Kafka Streams, real-time pipelines - Cloud & Infra: AWS (ECS, EKS, Lambda, DynamoDB, RDS), Terraform IaC, Docker - Observability: Datadog, Grafana, OpenTelemetry (built platforms from scratch) - AI Integration: RAG, MCP, agentic architectures on AWS Bedrock Enterprise background at JPMorgan Chase, Mastercard, Morgan Stanley, Citigroup, and SiriusXM. I treat AI as an accelerator, not an oracle — combining decades of distributed-systems expertise with modern tooling to deliver clean, reliable, production-ready solutions. Whether you need a streaming pipeline, a cloud migration, a scalable API, or an end-to-end backend service, I deliver work that holds up in production. Let's build something that scales.
