Multi-layer architecture. Obsidian vault as source, Claude Code as orchestration, MCP servers (filesystem / REST / browser / web / creative), typed auto-memory with bidirectional vault sync, topic-classified knowledge graph, curated portfolio layer with stage gates. A single operator running an AI-assisted professional workflow at production scale on commodity hardware.
Multi-cloud research environment. Static source review combined with live observable testing under multi-tier AI verification (Scout / Judge / Sonnet / Opus). Session Persistence Layer, Attack State Machine, Resource Lifecycle Actions, Multi-Hop Chain Planner across GCP / AWS / Azure. Discovery-aware hunting with forensic-trail capture.
Open-source PowerShell audit suite for Microsoft 365 and Cloudflare in small organizations. Audits five domains (Sentinel, Defender for Office 365, DNS and email authentication, Entra ID, Defender for Cloud) and produces a P1 / P2 / P3 ranked report with deployable remediation artifacts. Ships Sentinel analytics rule templates, KQL hunting drills, and email authentication baselines covering SPF, DKIM, DMARC, MTA-STS, and TLS-RPT.
view toolkitOpen-source security research with focus on Google gVisor (container sandboxing and Linux runtime behavior). Sustained contributions include TOCTOU fixes in systrap, TUN device crash handling, Go concurrency race fixes, guest-writable shared memory hardening. Additional upstream PRs across Google Tink (cryptography), Bumble (Bluetooth stack), osv-scanner (package security), and click (CLI tooling).
view merged contributionsForty-eight-hour multi-zone blue-team engagement against a live red team at Sierra College Cyber Defense Competition. Deployed Security Onion, Wazuh, Suricata, Zeek, and honeypots across WAN, DMZ, and LAN zones. Authored a Sigma rule pack, hunting queries, and a triage runbook for sustained adversary activity under time pressure. Public case-study repository at github.com/ibondarenko1/blue-team-engagement.

Running multi-cloud AI-assisted hunts via the ClearAhead pipeline. Paired-session live engine with multi-tier verification across GCP / AWS / Azure. Filing upstream PRs across Tink, gVisor, grpc, Bumble: the current batch covers AWS-KMS / GCP-KMS CRC32C integrity gates, gVisor nvproxy hardening, and grpc RBAC path canonicalization (sibling of CVE-2026-33186).
In parallel: live-fire blue-team practice under sustained operational pressure. Cloud-deployed lab pod with Security Onion 2.4, pfSense + Snort IPS, Wazuh agents, and a mixed Linux / Windows fleet, exercised against simulated adversary activity at production rate. Scope covers SOC alert triage, KQL pivot hunting, MITRE ATT&CK mapping, firewall and IDS tuning under load, and disciplined change management across reset cycles.
Response frameworks layered in as fallback discipline: CIS Critical Controls, NIST CSF, PCI-DSS, and HIPAA technical safeguards. Role spread across firewall, Windows, Linux, application, monitoring, and change-management leads, with shared runbooks for reset recovery and uptime continuity.
Two channels. One filter.
Open for OSS security collaboration, architecture review, full-time opportunities in detection engineering and security operations, and research dialogue. Cold sales routes to /dev/null.
