I build secure AI and business apps for complex workflows.
Cover image for I designed and developed an
I designed and developed an AI-assisted application-building system that supports product definition, architecture, code generation, testing, review, deployment and controlled iteration. Unlike unrestricted code generation, the platform uses structured workflows, specialist agents, human approvals, validation gates and deployment controls to create more accountable and reproducible software builds.

Cover image for Wholesale Growth & Buyer Discovery
Wholesale Growth & Buyer Discovery Platform I designed and built a full-stack wholesale growth platform that helps brands discover suitable retailers, identify buyer contacts, assess commercial fit and manage outreach through a structured sales pipeline. The platform combines boutique discovery, brand-to-retailer matching, buyer contact research, AI-assisted fit scoring, promotional outreach, follow-up tracking, deal-pipeline management and controlled CSV/CRM exports. I led the product concept, workflow design, system architecture, frontend, backend, database, testing and deployment.

Cover image for Drift Guard — AI Operational
Drift Guard — AI Operational Integrity and Resilience System I designed and built Drift Guard, an operational integrity system for monitoring complex AI and software environments for configuration drift, behavioural changes, degraded services and unexpected operating conditions. The system supports structured verification, operational checks, evidence capture and controlled response workflows, helping teams identify when a deployed environment has moved away from its approved state. I led the architecture, workflow design, development, validation, testing and final packaging of the system.

Cover image for Grid Delivery Control — Grid
Grid Delivery Control — Grid Connection and Commissioning Platform I designed and built Grid Delivery Control, a secure project-management platform for renewable energy, BESS and electrical infrastructure projects. The system brings grid-connection requirements, technical evidence, approvals, milestones, risks, commissioning records and handover documentation into one controlled workspace—from initial application through to energisation. Key capabilities include G99 and G100 workflow tracking, document version control, technical approval gates, readiness dashboards, project risks, commissioning test records, audit history and controlled handover reporting. I led the product concept, engineering workflow design, system architecture, frontend, backend, database, security controls, testing and deployment. This is an independently developed product created through my personal Replit workspace.

AI Agent Security Auditor | Fast, evidence-based reviews
Cover image for I recently completed a security
I recently completed a security hardening pass on an AI-enabled mobile product. The most important issues weren’t exotic vulnerabilities. They were practical deployment risks: password reset race conditions missing abuse controls weak retention guarantees mobile backup exposure logging and CI gaps Each confirmed finding was fixed and backed by regression tests before the security baseline was marked PASS. One lesson stood out: security reviews are most useful when they produce evidence and actionable fixes, not just scanner output. I’m now offering focused 24-hour AI Agent Security Mini-Audits for founders and small teams. https://contra.com/s/2Z7YgYXU-ai-agent-security-mini-audit?r=guillaume_strohecker_6m06cchc

Cover image for API Rate Limiting & Abuse
API Rate Limiting & Abuse Protection Security hardening focused on API abuse resistance. Rate limits were added to registration, login, password-reset request and confirmation, Click Intent creation, and public Heat reads. The limiter was designed with bounded state, explicit email normalization, case-sensitive reset-token fingerprints, expiry sweeping, and fail-closed behavior under saturation. Regression tests verified throttling behavior and recovery.

Cover image for Authentication & Password Reset Hardening Security
Authentication & Password Reset Hardening Security hardening focused on authentication and account recovery. The work included stronger scrypt password hashing, legacy-hash migration, login timing protections, atomic password-reset token consumption, and session revocation after reset. PostgreSQL concurrency and regression tests verified that a reset token can only be successfully consumed once and that authentication behavior remains safe under failure conditions.
