Profile

Engineer who works where software meets business operations. As a founder and operator I discovered problems inside live workflows, translated them into requirements, architected the systems, built them full-stack, deployed them, and operated them in production: payments and reconciliation, realtime market data, background processing, applied AI features, and the internal tooling behind them. I practice disciplined AI-assisted development, pairing engineering ownership with context engineering, human-in-the-loop review, and verification. Targeting software, full-stack, product, and application engineering roles, including applied AI and forward-deployed opportunities.

Experience

Velocity Funds / Velocity Co.

2025 – Present

Founding Product Engineer

  • Translated the business model itself into software requirements: evaluation rules, payout eligibility, risk enforcement, and the operational workflows behind them.
  • Designed and shipped the trader platform: onboarding, evaluation dashboards, real-time account tracking, analytics, and AI-assisted performance features (OpenAI, versioned prompts, model routing, streaming).
  • Built the financial infrastructure: checkout and payment webhooks with idempotency handling, entitlements, payout eligibility, and reconciliation against provider records.
  • Owned the production database, PostgreSQL on Supabase with row-level security, timestamped migrations, and realtime publications, through a real launch and its post-launch incidents.
  • Ran the supporting systems: transactional and campaign email, an internal CRM view over platform data, a Discord operations bot, and the public marketing site.

Advanced Recovery Group

2024 – Present

Account Manager

  • Translated a live collections workflow's unwritten rules (account cadence, settlement stages, payment plans) into working software while performing the work it supports.
  • Built CSV-first onboarding tolerant of messy real spreadsheets: fuzzy header mapping, deduplication keys, and multi-format date normalization.
  • Encoded the operational rules directly: age-based follow-up prioritization, at-risk flagging, and month-end payment archival.
  • Refined the software's terminology and behavior from daily use inside the operation.
