Work Experience
Full Stack Developer
CyberAIX
- Designed and implemented a high-concurrency reservation engine using Node.js, MySQL, and Redis, successfully managing thousands of concurrent users and real-time seat allocations during peak traffic bursts.
- Eliminated double-booking errors by implementing transaction-safe row-level locking and ACID-compliant concurrency controls for simultaneous booking attempts.
- Reduced API latency by ~90% by re-engineering synchronous workflows into an event-driven architecture using Redis queues BullMQ background workers for the "Print-at-Desk" service.
- Optimized multi-core CPU utilization by scaling backend infrastructure with Node.js clustering and worker threads, sustaining 4x higher request throughput under peak load compared to baseline.
- Engineered fault-tolerant payment systems with idempotent endpoints and transactional safeguards, ensuring zero duplicate charges and 99.9% reliable payment handling.
- Developed a robust authentication flow featuring asymmetric JWT signing, refresh token rotation, and OTP-gated access to prevent unauthorized session persistence.
- Architected Defensive API Layers via the API Gateway, implementing adaptive rate limiting and strict schema validation to mitigate Layer 7 DoS and injection-based vulnerabilities.
- Enhanced data retrieval performance through optimized SQL indexing, cursor-based pagination, and Redis caching, enabling real-time analytics with sub-second response times.
Web Developer
HotStuff Labs
- Delivered real-time trade feed updates for a live trading platform using event-driven data flows, reducing UI staleness from polling delays to near-instant push updates.
- Led migration of wallet integration from ethers.js to Viem, reducing bundle overhead and improving type safety — migrated without production downtime across existing user sessions.
- Built a live trade tape component displaying the latest 20 executed trades in real time, and integrated TradingView charts connected to existing backend market data endpoints.
Projects
StableCoin
- Designed a minimalistic algorithmic stablecoin maintaining a 1 token = $1 peg through exogenous collateralization.
- Implemented a collateral-backed stability model similar to DAI but without governance overhead or protocol fees.Built smart contracts backed solely by WETH and WBTC collateral pools focusing on deterministic stability.
