- Authored reference solutions, evaluation rubrics, and scoring guidance to help reviewers assess correctness, instruction following, and code quality.
- Investigated model failures and calibrated technical reviews, resolving ambiguous cases through reference implementations and explicit evaluation criteria.
Engineering Manager
Insurify
- Managed 10 engineers on an Insurify client engagement, combining delivery planning and mentoring with hands-on architecture and code reviews.
- Led enterprise product development across React applications, Python services, and partner APIs, supporting insurance comparison journeys and new product verticals.
- Built Next.js verticals, including Compare Finance, and integrated Braze and Klaviyo workflows for customer retention and consent synchronization.
- Implemented analytics and marketing integrations using Google Tag Manager, gtag, and advertising pixels, and supported automated QA workflows.
Consultant and Full-stack Developer (Part-time)
Yogi & Associates
- Built Django accounting operations software with client records, permissions, and activity logs backed by PostgreSQL.
- Developed document extraction, transaction review, OpenAI-assisted categorization, and Excel exports for accounting workflows.
- Automated background jobs with Celery and Redis and integrated AWS storage, Microsoft Graph, Stripe, and Twilio.
Full-stack Engineer

- Updated browser-based interfaces and migrated complex components to AngularJS and later Angular.
Project History
Difficulty Augmentation | RLVR Task Calibration
https://www.youtube.com/watch?v=1-glLAhmeA4My contributions included reusable task libraries, calibration results, deterministic grading, worker routing, cancellation, and access controls. I also investigated agent runs that stalled after terminal errors and improved stop propagation, cleanup, and diagnostics. Tasks run in reproducible environments and are judged by concrete checks, rather than by whether an answer sounds convincing. The video walks through the task-calibration workflow.
Review Desk | AI Pull Request Review Agent
https://www.youtube.com/watch?v=G6qprW-1lnQI built the review workflow, GitHub integration, and safeguards with duplicate findings being filtered, file and line references being checked, and publication being blocked if the pull request changes during the run.
The application uses TypeScript, Fastify, React, SQLite, and the Cursor SDK.
Expert Confusion Buster | LLM Assessment Workflows
https://www.youtube.com/watch?v=pyWiNjDMJ2UMy work covered OpenAI integration, structured response validation, recovery from malformed model output, retries, adversarial filtering, and retake controls. I worked across the Python/FastAPI back end, React interface, and PostgreSQL data layer.
The focus was on making the assessment workflow dependable when model responses were incomplete or inconsistent.
Insurify | Product Modernization and Financial Verticals
My work included migrating Backbone interfaces to React, moving WordPress sites to Gatsby, and building Next.js verticals such as Compare Finance. I also contributed Python microservices and partner APIs, integrated Braze and Klaviyo retention workflows, and implemented consent synchronization and analytics using GTM, gtag, and advertising pixels.
Alongside implementation, I reviewed designs and code and mentored engineers.
CV Parser | Structured Candidate Review
https://www.youtube.com/watch?v=CeH0qzacykAMy contributions included domain taxonomy, multi-sheet views, saved views, and deployment work. The workflow makes extraction failures explicit instead of silently treating missing data as a valid result. I focused on making the output useful for day-to-day review by using consistent categories, practical filtering, and views users can return to.
The video demonstrates the candidate-review workflow.
PVV | Reproducible Verification for AI Coding Tasks
My work covered verifier execution, concurrency controls, resource logging, and retry handling. The pipeline checks baseline failures and reference-solution passes rather than trusting a model's explanation of success.
This gave reviewers concrete evidence of execution when assessing task quality and diagnosing unreliable runs.
Accounting Operations | Document Extraction and Review
My work covered Django/React features, permissions, activity tracking, OCR-based transaction extraction, OpenAI-assisted categorization, and Excel exports. Background jobs use Celery and Redis, with integrations including Microsoft Graph, Stripe, and Twilio. I built the review steps so users can inspect and correct extracted information before using it in their accounting work.
This was part-time consulting work for Yogi & Associates.
