What makes this different from staff augmentation?

One person with seven specializations unavailable in staff aug. COBOL PICTURE-clause forensic find in 127 minutes that 3 years of external audits missed. 3-5x lower cost for broader coverage.

Is the sovereign inference cluster operational?

Yes. 55 commits ahead of upstream on a production fork of exo (upstream lineage). RDMA ring topology. 389ms P50. AWS Bedrock and Azure OpenAI format-compatible. $26,400/mo cloud inference eliminated.

What audit-trail artifacts does the sovereign inference build produce?

SHA-256 hash-chained chain-of-custody on every inference output. Quality-management-system documentation, bias logs, and human-oversight records with a deterministic event-sourced audit trail, operational now.

What compensation are you targeting?

Negotiated privately, by role and scope — remote · W2 · skills-first.

100% remote. US-based, Mountain Time. Async-first. No relocation.

What kind of engineer are you?

Agentic architect and AI/data engineer — agentic systems, sovereign inference infrastructure, and adversarial-AI validation, every result replay-verifiable.

What proof do you offer?

Deterministic replay artifacts. SHA-256 hash-chained chain-of-custody. COBOL PICTURE-clause forensic audit in 127 minutes. 27× throughput. 96% latency cut. 0 false negatives across the public adversarial corpus (140/140 caught, n=220). All verifiable at puodziukas.dev/proof.

Why hire you instead of engaging a consulting firm?

Single operator, full-time, inside your perimeter. The person who scoped the work does the work — every output logged and replay-verifiable.

Yes. Standard MNDA on day one. All work product stays air-gapped.

What stacks do you work in?

COBOL · Rust · Python · TypeScript · Next.js · LLM APIs · AWS · GCP · Terraform · Pulumi · OpenTelemetry · NIST FIPS 203/204/205.

Forward Deployed Engineer

COBOL PICTURE-clause forensic audit in 127 minutes. 6 regulated domains. COBOL + AI reproducible reference implementations, plus post-quantum migration readiness.

COBOL PICTURE-clause truncation. COBOL. 127 min. Undetected for years. Board-reproducible.

The problem

An enterprise client running payroll on COBOL raises three questions in the same meeting: post-quantum readiness from the CISO, adversarial validation of the LLM layer from engineering, and whether the COBOL arithmetic is even correct. Few engineers carry all three at once.

What exists, reproducible

COBOL forensics and LLM adversarial validation, demonstrated together across reproducible reference implementations spanning 6 industry domains, plus FIPS 203/204/205 post-quantum migration readiness.

→COBOL PICTURE-clause fixed-point truncation: found via forensic replay, compounded undetected
→FIPS 203/204/205 post-quantum migration readiness: standards and the 2030 NIST migration timeline mapped, harvest-now-decrypt-later exposure assessed
→Adversarial validation harness: deterministic replay + hash-chained audit trail, built per environment
→6 industry domains addressed: healthcare, finance, insurance, defense, mainframe modernization, agentic
→Deterministic replay corpus: COBOL upstream batch arithmetic verified byte-for-byte against source
→Deterministic replay over a 47,312-record deterministic replay corpus, 0 divergence + adversarial gate 140/140 caught (0/80 over-blocked, public n=220)
→Day-1 adversarial scope: no discovery phase, no ramp time. Scope memo in 24 hours.
