Clear, practical security engagements without unnecessary enterprise bureaucracy. I identify risks, fix vulnerabilities, and help you pass vendor audits.
Pre-Audit Checklist & Service DeliverablesSecurity Assessments & Code Audits
SMEs deploying web apps or cloud services
I audit your application code, dependencies, and cloud configuration. I identify logic flaws, access control bugs, and OWASP Top 10 vulnerabilities before release.
Deliverables
- •Manual code and architecture review
- •OWASP Top 10 and API vulnerability scan
- •Prioritized remediation report with actionable diffs
Incident Response & Post-Mortems
Teams facing active or recent security incidents
I assist in containing unauthorized access, identifying root cause compromise vectors, revoking compromised credentials, and hardening systems against re-entry.
Deliverables
- •Log and audit trail analysis
- •Credential and session token rotation
- •Clear post-incident root cause documentation
Compliance Readiness (SOC 2 & NIST)
Startups and SMEs seeking vendor qualification
I help prepare your systems, access policies, and audit trails for SOC 2 Type I/II, ISO 27001, and NIST CSF assessments without unnecessary overhead.
Deliverables
- •Least-privilege RBAC role mapping
- •Audit logging and retention policies
- •Technical evidence collection for external auditors
Secure Web Application Builds
Companies building new customer-facing software
I build full-stack web platforms using Next.js 16, Python FastAPI, and PostgreSQL. Every build includes strict access controls, session hardening, and automated CI tests.
Deliverables
- •Server-rendered Next.js + FastAPI architectures
- •Role-based access control and type-safe databases
- •Security-hardened deployment on Vercel and Docker

Attack Surface & DNS Hygiene
Port audits, SPF/DKIM/DMARC posture, TLS 1.3 configuration, public endpoint exposure.
NIST ANSI INCITS 359 RBAC & Session Review
HTTP-only cookie architecture, XSS/token theft mitigations, monotonic role hierarchy enforcement.
OWASP API Top 10 Vulnerability Audit
IDOR verification, broken object authorization, rate limiting, and SQL injection parameterization proof.
SOC 2 / ISO 27001 Compliance Readiness
Vendor security questionnaire prep, audit-ready data boundary proof, and evidence dossier creation.

Detailed breakdowns of real systems: disaster relief workflows, subpath-isolated internal portals, and asynchronous API microservices.
Kestrel Relief — Humanitarian Aid Operations
Emergency operations web platform with donor processing, volunteer dispatch, and an 8-role administrative hierarchy operating over 384,200 seeded crisis records.
Humanitarian aid groups often track field disbursements across messy spreadsheets and unvetted third-party forms. This leads to leaked civilian records, duplicate aid allocations, and unverified financial reporting.
I built a centralized Next.js 16 and PostgreSQL platform using Drizzle ORM. I implemented an 8-tier role-based access control system conforming to NIST ANSI INCITS 359. Public donor flows are strictly separated from sensitive beneficiary logs, and Stripe payment webhooks require HMAC-SHA256 verification.
The system reliably indexes 384,200 seeded beneficiary records across 12 simulated emergency zones. Queries execute with 100% parameterization, preventing SQL injection, while HTTP-only session cookies reduce token theft via XSS.
Enterprise Workspace — Subpath Operations Hub
Corporate staff portal deployed on an isolated subpath (/emp) with zero public bundle dependencies and strict network origin restrictions.
When internal admin tools share client bundles with public marketing websites, internal API routes and tokens frequently leak into public JavaScript bundles and search engine indexes.
I isolated the internal workspace into an independent repository and Vercel project using subpath routing (/emp). The application enforces noindex/nofollow headers, strict CORS rules, and server-side session checks before serving any HTML.
Internal code, credentials, and API structures are completely absent from public site bundles. Search crawlers are blocked, and cross-origin requests from outside approved corporate domains are rejected at the edge.
TMI Enterprise Hub & Headless CMS
Corporate monorepo coupling a Next.js 16 App Router frontend with an asynchronous Python FastAPI service, featuring full CRUD admin controls and departmental message routing.
Monolithic agency websites often suffer from tight coupling between content presentation and backend business logic, making it difficult to apply strict security controls to administrative workflows.
I engineered a decoupled monorepo: Next.js 16 frontend on Vercel paired with an asynchronous FastAPI backend on Render. All API endpoints enforce strict Pydantic schemas, password hashing via Bcrypt, and parameterized database queries via SQLAlchemy 2.0 with Alembic versioning.
The application provides full CRUD content management and inquiry dispatch with sub-second page transitions, automated OpenAPI schema validation, and zero SQL injection surface.

Threat Model: Kestrel Relief Field Ingress & Beneficiary Privacy
Problem & Context
Threat modeling of an emergency relief platform handling aid allocation across 12 simulated zones. Examined volunteer mobile endpoints, donor webhooks, and administrative records.
Architectural Analysis & Invariants
- Identified Spoofing risks on payment callbacks: enforced HMAC-SHA256 signature validation with replay timestamp checks on Stripe webhooks.
- Addressed Information Disclosure of vulnerable civilians: separated public fundraising registries from beneficiary records, enforcing UNHCR field redaction rules.
- Mitigated Tampering risks in volunteer inventory tracking: all state mutations require authenticated server actions with parameterized Drizzle ORM queries.
