Security-First Engineeringfor Production Systems
I help teams uncover hidden risk, harden live infrastructure, and design systems that fail safely — before attackers or outages do it for them.

Security Engineering
for Production Systems
From security audits to adversarial testing to system hardening — methodical approaches to securing your critical infrastructure.
Risk Assessment
Security & Failure Audits
Systematic review of your production systems to identify vulnerabilities, failure modes, and security gaps before they become incidents. Clear findings, prioritized remediation.
Penetration Testing
Adversarial Testing
Controlled offensive security testing against your live systems. I think like an attacker so you can defend like one. Comprehensive reports with exploitation paths and fixes.
Defensive Engineering
System Hardening & Guardrails
Implementing fail-safe defaults, rate limiting, input validation, and defense-in-depth controls. Building systems that fail closed, not open.
Fit
Good fit if / Not a fit if
Good fit if
- You have live users, real assets, or production risk
- You're launching, scaling, or recovering from an incident
- You want actionable fixes, not security theater
Not a fit if
- You need a checkbox compliance report only
- You're pre-MVP with no real production risk
- You want a pentest PDF with no remediation support
Engagement Flow
Risk discussion
Define critical paths, assets, and failure boundaries.
System mapping
Threat model the system, attack surface, and assumptions.
Adversarial review
Test boundaries, permissions, and misuse cases.
Hardening + handover
Ship guardrails, validate fixes, and leave runbooks.

Security-Driven Transaction UX
Security Patterns Implemented
- Simulation gates before send
Transactions simulated and validated before submission
- Irreversible-action acknowledgement
Explicit user confirmation for destructive operations
- Confirmation reliability guarantees
Transaction finality verified with retry logic
- Clear timeout semantics
Explicit expiration handling for pending operations
- Recovery + incident readiness
Graceful degradation and rollback capabilities
async function executeTransaction() {
// 1. Simulate first
const simulation = await simulate(tx);
if (!simulation.success) throw SimError;
// 2. Require explicit ack
await requireUserAck("irreversible");
// 3. Submit with timeout
const result = await submitWithTimeout(
tx, { timeout: 30_000 }
);
// 4. Verify finality
await waitForConfirmation(result.sig);
}How I Build
Secure Systems
Phased Rollouts
Incremental deployments with rollback capability. Changes validated in stages before full production.
Fail-Closed Design
Systems default to secure state on failure. No silent failures that leave doors open.
Explicit Acknowledgements
Irreversible actions require explicit user confirmation. No accidental data loss.
Confirmation Reliability
Operations verified to completion. No fire-and-forget for critical actions.
Clear Timeout Semantics
Every async operation has explicit timeout handling. No indefinite hangs.
Recovery Playbooks
Documented incident response. Known paths from any failure state back to healthy.
