About

До этого в GMG собирал high-load сервис в gamedev — event-driven CQRS, кэш, очереди, 25k+ онлайна, P95 меньше 25 мс — и RAG-пайплайн для саппорт-бота: инжест, retrieval, Kafka между сервисами. Есть свой продукт 2Food: полный цикл от архитектуры до Kubernetes и прода. Ищу mid applied AI: живой RAG, агенты в backend, внутренние инструменты для аналитиков. Remote или релок, готов говорить по-русски и на рабочем английском.

Experience

Softeare Engineer

KASE

May 2025 — Present

Built a Rust FFI wrapper over Aeron IPC for low-latency C/C++ communication, achieving 10M mes- sages/sec via batching, zero-copy, and memory layout optimization. • Designed low-latency data pipelines for Market Data Feed processing – ingestion, normalization, and real-time delivery. • Developed Solana smart contracts (Anchor) for on-chain logic and transaction processing. • Built a RAG assistant for analysts over YouTrack: indexed tickets and comments, retrieved relevant issues, and generated context-aware answers for investigation and reporting.

Software Engineer

GMG

Mar 2024 — Apr 2025

• Drove the architecture for a real-time leaderboard service using event-driven CQRS (Python, FastAPI, PostgreSQL, Redis), decoupling write/read paths to support 10k+ DAU and 25k+ concurrent users at P95 latency under 25ms. • Applied high-load and reliability practices – connection pooling, caching, idempotent event handling, and a NoSQL read store – achieving 99.99% uptime. • Built a RAG pipeline for an AI support bot: document/event ingestion, retrieval, and Kafka-based streaming between services.

Backend Developer

Altyn Bank

Jun 2023 — Jan 2024

• Improved performance of a critical banking service by migrating blocking code to asynchronous C#, reducing response time from 200ms to 100ms, and increased test coverage to 85%.

Fullstack Developer

2Food

Sep 2025 — May 2026

• Co-founded and led all engineering for a two-sided food-rescue marketplace (Go, React Native, PostgreSQL, Redis, Kubernetes). • Architected Clean Architecture backend with async job pipeline (Asynq) for order processing and notifications. • Integrated third-party services: Stripe (payments), Twilio (SMS), Firebase FCM (push notifications). • Shipped to production with GitOps CI/CD (ArgoCD); piloted with real restaurants and beta users.
