Experience#

Consultant 2023–2026

• Increased employee leverage and time by outlining an AI adoption plan, building MCP servers to connect internal systems, and teaching Claude Code/Cowork.
• Instrumental in closing $50k+ in client contracts by architecting and building a real-time idea refinement tool, used in pitches, where Anthropic Claude personas collaboratively debate and refine user prompts.
• Scaled an AI-debate platform to thousands of concurrent WebSocket sessions by migrating a Python prototype to Cloudflare (Workers, Durable Objects, D1), preceded by an architecture decision record.
• Empowered non-technical contributions from 6 stakeholders submitting pull requests by designing on-ramps and guardrails, saving engineering from reviewing "AI slop."

Senior Software Engineer/Tech Lead — Patch Media 2019–2023

• Accelerated shipping frequency on major product initiatives from 2–3 months to every 2 weeks by revamping the technical roadmap while keeping stakeholder buy-in.
• Boosted native app development speed by rebuilding the iOS and Android offshore apps in-house with full data migration, phased rollout and zero downtime, and teaching agile development.
• Hired and mentored junior engineers to promotions through 1-1s, pair-programming, code review, architecture design docs, and co-created talks.

Cedric is the best technical partner I've had the pleasure to work with. He amplified our team's work through thoughtful team process improvements and inventive technical solutions that saved us time and energy. His endless passion to meet the needs of the user is a dream for every product manager.

Consultant — Ulster County Department of Health 2020

• During the first weeks of COVID lockdown, decentralized the COVID help hotline team to operate safely from home — by shadowing 30 in-office team members, replicating their process using no-code tools, and seamlessly transitioning county employees onto these tools, all with no downtime.

If you don't pull this off we are fucked.

Co-Founder — Hansel Invest 2017–2019

• Improved DX and reduced unit tests while increasing code confidence by teaching and implementing both React & TypeScript across 4 products used by millions of users.
