Engineering notes from Buenos Aires.

Accelerating the Modern Data Stack: Integrating Arrow, GPUs, and Rust with Craton Bolt

Craton Bolt is a JIT-compiled GPU SQL engine built in pure Rust. By keeping data in Arrow-aligned device buffers and fusing query kernels into a single PTX program, it eliminates the serialization and PCIe overhead that has historically made GPU analytics impractical.

Solving the AI Cold Start Problem: Scale-to-Zero Inference with WebAssembly

How Craton TensorWasm combines Wasmtime, memmap2 zero-copy snapshotting, and cryptographic verification to boot a multi-gigabyte GPU model in under 150 ms — making true serverless AI economically viable.

Benchmarking Craton HSM: Baseline, Optimized, and vs. SoftHSMv2

A rigorous three-phase benchmarking study: raw crypto baseline, targeted optimizations (57% AES-GCM speedup, O(1) FindObjects), and a definitive head-to-head comparison through the PKCS#11 C ABI against SoftHSMv2 v2.6.1.

Zero-trust vehicle security with Craton Shield

Why CAN IDS, SecOC, and V2X are converging on a single #![no_std] Rust stack — and what that means for Tier-1s and OEMs.

Why we rewrote SoftHSM in Rust

Buffer overflows in attribute parsing, use-after-free in session lifecycle, double-free in error paths. The case for a PKCS#11 v3.0 HSM with zero unsafe in crypto paths.

Aether: beating gzip-9 with a neural state-space model

A diagonal linear SSM with 66 parameters, adaptive from scratch per block. 17.1% smaller than gzip-9 on the Silesia Corpus.

HSM for fintech compliance in LATAM

Why payment processors in Argentina, Brazil, and Mexico are re-evaluating their cryptographic stack, and what a FIPS-ready software HSM changes.

Why We Rewrote SoftHSMv2 in Rust

Craton HSM is a memory-safe, post-quantum-ready PKCS#11 software HSM in Rust — a modern replacement for the unmaintained SoftHSMv2.

Nearshore vs offshore: the Argentina case for NA mid-market

Timezone overlap, engineering seniority, and the arithmetic that makes Buenos Aires a rational answer for North American mid-market teams.

Digital transformation without a two-year megaproject

Thin-slice rebuilds, one workflow at a time. How we took a kitchen manufacturer from a 14-tab Excel macro to a 40-minute quoting pipeline in 10 weeks.

MSP for specialized stacks: what the generic shops miss

When your production systems include Postgres clusters, HSMs, and embedded gateways, the average MSP runbook is a liability, not an asset.

Technology consulting for the mid-market, minus the theatre

Architecture reviews that end in a written document, not a slide deck. Due-diligence that survives a re-read two years later.

A Rust adoption playbook for teams that already ship

Incremental Rust in a C or Python codebase — what to migrate first, what to leave alone, and how to keep the old build green while the new one lands.

IT services for 120-seat companies that are not IT companies

You do not need an MSP that pretends to be a helpdesk for a Fortune 500. You need someone who can keep your 120-seat business running, and leave when they are not needed.
