About Me
DX • Systems Engineer
Hello! I am a software engineer and technical lead specializing in high-throughput distributed systems, embedded key-value databases, low-level operating system hooks, and Web3 / EVM smart contracts.
My work centers on solving critical performance bottlenecks: from embedding CockroachDB's Pebble LSM storage engine for sub-millisecond 60Hz spatial telemetry, to replacing default Windows desktop shells with resilient Flutter kiosks and engineering gas-optimized AMM trading math.
Experience & Projects
Gridfacs
Tech Lead • Feb 2024 – Nov 2025Android/iOS real-time geolocation-based gaming engine.
- Architected a low-latency spatial indexing engine embedding CockroachDB's Pebble KV store directly in Go microservices, achieving 45µs range scans.
- Implemented bidirectional gRPC streams for real-time mobile delta updates and state sync.
- Built Three.js 3D lootbox opening experiences and integrated Redis distributed locks and RabbitMQ message broker.
Nima Labs
Software Engineer • May 2025 – Jan 2026Smart contracts & high-throughput EVM event indexing pipelines.
- Developed gas-optimized EVM smart contracts in Solidity with structured storage layouts and events.
- Constructed a fault-tolerant indexing engine in TypeScript that automatically handles deep blockchain chain reorganizations (reorgs) and RPC load balancing.
S-mon
Tech Lead • Sep 2024 – Feb 2025Commercial game facility management & custom OS kiosk environment.
- Replaced the default Windows Explorer shell with a custom desktop UI built in Flutter, interfacing directly via Dart FFI to Win32 APIs.
- Created Windows background services and low-level keyboard/process hooks to prevent terminal abuse and enforce strict session leases.
- Engineered the centralized NestJS backend communicating via WebSockets for real-time timer synchronization and remote administration.
RENTSKIS
Tech Lead • Nov 2023 – Jan 2024Ski and sports equipment rental platform for resort cashiers, admins, and technicians.
- Led full technical architecture from scratch, integrating ESC/POS thermal receipt printers and USB barcode hardware in pure Dart.
- Engineered an optimistic offline-first local SQLite sync engine to maintain continuous service during seasonal mountain internet drops.
