Building a Git-based backend for Music Blocks so thousands of creative coding projects can move from a legacy MySQL store into durable, searchable GitHub-backed repositories with ownership, history, and room to grow.

• Designed the migration path for 10,000+ user projects from MySQL to GitHub with persistent version history and ownership.
• Built a streaming migration pipeline that processes projects in under 5 seconds each with in-memory transformation and resumable checkpointing.
• Engineered a SQLite + REST API layer that brings search and retrieval latency from roughly 200ms via GitHub API reads to under 1ms locally.
• Designed around GitHub's 5,000 req/hr API limits by offloading read-heavy browsing and search to SQLite across 10K+ repositories.
• Implemented SHA-256 deduplication to eliminate redundant storage and improve migration efficiency.
• Developed 7+ production-grade endpoints for search, browse, like, and publish flows while preserving legacy feature parity.

Working on quantum-assisted scheduling for heterogeneous memory systems, using optimization models to decide where tasks should live across DRAM and CXL-like memory tiers.

• Designed a quantum-assisted scheduling engine with RQAOA to optimize task placement across DRAM and CXL memory tiers.
• Formulated scheduling as a QUBO problem, modeling memory latency from 80-400ns alongside capacity constraints for task allocation.
• Built a hybrid optimization system with Qiskit, OpenQAOA, and classical solvers for recursive combinatorial problem reduction.
• Simulated CXL-like memory architectures using NUMA and controlled memory binding with numactl for realistic performance evaluation.
• Developed an end-to-end optimization to scheduling to execution pipeline for heterogeneous memory conditions.
• Evaluated latency, throughput, and task completion time across multi-tier memory system configurations.
