Frontier AI Systems & GPU Performance

Stop burning millions on GPU waste. We engineer the metal, memory, and compilers underneath your models.

Most AI teams treat models like web development with prompt strings. We engineer the underlying hardware and memory hierarchy: eliminating KV cache memory bloat, fusing handwritten Triton and CUDA kernels, bypassing the Python GIL, and disaggregating prefill/decode pipelines to slash GPU costs by 30%–60% while cutting token latency in half.

KV Cache & HBM3e Memory Mastery

Context windows are memory-bandwidth bound, not compute bound. We re-engineer KV cache allocation, compaction, and quantization to fit 3x more concurrent users per GPU without quality degradation.

Handwritten Triton & CUDA Kernels

Replace standard PyTorch composite operators with custom, fused GPU kernels executed in on-chip SRAM registers—eliminating memory bus round-trips and driving down latency.

Free-Threaded CPython & Zero-GIL Runtimes

Unlock true multi-threaded CPU serving orchestrators feeding 8 to 16 GPUs simultaneously without Python Global Interpreter Lock contention.

Direct Production PRs (Zero Slop)

We don't deliver slide decks. We deliver minimal, durable, mathematically verified pull requests directly into your production serving engine with full regression coverage.

What we offer

01KV Cache & Memory Hierarchy Optimization — PagedAttention, FlashInfer, prefix caching, and outlier-aware FP8/FP4 quantization that cuts VRAM footprint by 60%
02Custom Triton & CUDA Kernel Fusion — Fusing multi-head attention, RMSNorm, and RoPE into single-pass on-chip SRAM kernels with zero memory round-trips
03CPython 3.14t Free-Threaded (PEP 703) Acceleration — Module slot initialization (Py_mod_gil) and zero-GIL concurrency bridges (proven in OpenAI Triton #8491)
04Low-Latency Disaggregated Serving — Prefill-decode split architectures over RDMA and speculative draft decoding for sub-50ms Time to First Token (TTFT)
05GPU Cluster Utilization Audits — Maximizing Model Flops Utilization (MFU), diagnosing PCIe/NVLink bottlenecks, and eliminating idle GPU overhead
06Production Serving Stack Hardening — Custom vLLM, TensorRT-LLM, and SGLang orchestration with zero-defect invariant release gates
