Associate Engineering Manager|Agentic Workflow Architect
Architecting high-integrity agentic workflows that transform natural language directives into governed engineering outputs. 🧭
Staff-Track AI Engineering Manager · Agentic Workflow Architect — I design high-integrity agentic workflows for regulated fintech, most recently as Associate Engineering Manager at Aspire. I led a team of backend, mobile, web developers and QA engineers — 60% management, 40% hands-on across the full stack including QA test suite reviews.
Diagnostic Intelligence · Incident Automation · System Governance — My core initiative at Aspire was an Automated Incident Diagnostic Engine. It analyzes issue reports, evaluates the completeness of incident descriptions, and when sufficient data is available, extracts domain-specific source code to predict root-cause hypotheses with confidence scoring. Engineered to accelerate on-call recovery while maintaining production security and safety.
Aura Frog Platform — I created Aura Frog, an open-source AI engineering OS for Claude Code, portable to Cursor and other AI platforms. Multi-agent orchestration through a 5-Phase TDD lifecycle (Vision → Test RED → Build GREEN → Refactor → Finalize), governance rules that enforce code invariants, and MCP skill bundles that let agents reach into the developer's tools.
Engineering Leadership & Systems Architecture
Designing agentic engineering workflows for regulated, cross-border fintech
Engineering Leadership
- •Managed 2 cross-functional sub-teams (10 engineers) covering Backend, Frontend, Mobile, and QA.
- •Ensured domain ownership clarity across fintech modules during VP-level reorganization.
- •Balanced sprint allocation: 60% feature delivery / 40% technical investment.
- •Structured knowledge transfer processes to prevent domain silos and ownership fragmentation.
- •Cross-functional stakeholder alignment with structured design review culture.
Strength: Multi-team governance with delivery stability through organizational change.
Distributed Financial Systems
- •Implemented row-level locking and transactional integrity boundaries for high-frequency financial updates.
- •Designed snapshot accounting tables to reduce real-time computation pressure.
- •Built concurrent test simulations to validate race-condition safety.
- •Reduced database load ~30% and improved system reliability under concurrent writes.
Strength: Concurrency-safe architecture ensuring zero data corruption in production financial systems.
AI Systems & Orchestration
- •Architected the AI Incident Diagnostic Engine — Jira webhook trigger, LLM-based gap analysis, and DRI routing.
- •Delivered deep diagnostics layer that pulls latest source code and predicts root-cause hypotheses, every output annotated with a confidence score for human-in-the-loop decisioning.
- •Designed Aura Frog — an open-source AI engineering OS for Claude Code, portable to Cursor — that orchestrates multi-agent workflows through a 5-Phase TDD lifecycle.
- •Codified governance rules and commands that constrain agent behavior, enforce code invariants, and extend execution surface via MCP skill bundles.
Strength: High-integrity agentic workflows that transform directives into governed engineering outputs.
AI Adoption Strategy
- •Defined AI usage guardrails and structured prompt standards for regulated fintech environment.
- •Designed experimentation evaluation framework covering risk assessment, rollback strategy, and adoption criteria.
- •Assessed infrastructure readiness: monitoring, logging, and service isolation for AI integration.
- •Defined 3-phase AI adoption roadmap: internal productivity, workflow automation, and customer-facing AI.
Strength: Risk-aware AI adoption strategy that balances innovation with regulatory compliance.
