Senior Engineer — Architecture & Platform
Contract-intelligence platform that governmental, defence and infrastructure clients run their post-execution obligations on — multi-billion-dollar programs where a missed clause-driven deadline can trigger eight-figure liquidated damages. Work spans the hardest subsystems: task orchestration, identity & SSO, document linking and clause graphs, cloud and network infrastructure on GCP, security review, and reliability for long-running data pipelines.
- 01Platform architecture: sole author of the production Celery framework (+10,787 LOC, 42 files, 50+ legacy jobs ported, multi-tenant context restoration). Runtime owner two years post-launch.
- 02Full-stack rewrite of the core checkout-status workflow end-to-end — 10 months, 8 versions, Python / SQLObject + ExtJS + Angular. Touches every customer transaction.
- 03Production incident command: recurring commander for DB-lock and stuck-job classes. Hot-fixed a production lock-up caused by an unguarded dblink call; eliminated a lock-contention class serialising every admin operation behind concurrent check-ins on multi-thousand-book libraries.
- 04Security research: four pre-disclosure vulnerability reports in 30 days (subdomain takeover, CSRF/PRNG, SMS-MFA bypass + ATO chain, leaked-credential audit) — each in executive register with ISO 27001 framing and a remediation plan.
- 05De-facto owner of CI/CD orchestration, the mypy type-safety pipeline and the compliance notification system. Authored a Claude Code slash-command suite in production team use; built an MCP-driven evidence pipeline; analysed a 1,000-MR review corpus for a pre-merge tooling proposal.
- 06Compliance: implemented technical controls supporting GDPR, CCPA, ePrivacy and ISO 27001 across platform domains. Authored the regulatory-comparison matrix for cookie-consent; chose strictest-GDPR posture over geo-fencing.
- 07Footprint: 200 MRs at 61.5% merge rate · 35 teammate MRs reviewed · 17+ initiative branches owned end-to-end · 138 tickets shipped across seven subsystem themes · top-4 contributor (710+ commits) in a 10+ person team.
