Work Experience
Mobile Full-stack Developer
CG FAST SOLUTIONS LLC
- Architected and shipped a live personal finance app to the App Store. Took over a vibe-coded React Native app, fixed the security issues these apps usually carry, and moved every third-party API call into a Node.js back end with PostgreSQL.
- Built the full authentication and authorization flow. Users sign in with email, phone OTP, Google or Apple, with OTP codes sent through Twilio and SendGrid, and can lock the app with Face ID or fingerprint.
- Integrated Plaid to link users' bank accounts and sync their transactions, cash flow, loans, investments, and interest, then turned that data into clear views of spending, net worth, debt, subscriptions, and bills.
- Built a debt calculator that compares snowball and avalanche payoff, plus savings goals that track progress against linked accounts.
- Integrated Array so users can connect their credit profile, see their credit score, and enroll in identity and privacy protection. Users can also add their house and car to get estimated values.
- Built the subscription system with Stripe. Every feature is plan-gated, new users get a 30-day free trial, and upgrades, downgrades, and trial expiry stay in sync with Stripe.
- Created Hey-B, an AI financial advisor running an NVIDIA Nemotron model on Amazon Bedrock. It answers only questions about the user's own finances, reads their data through back-end tools, blocks off-topic questions, and strips sensitive details.
Technical SEO Engineer (WordPress)
Fortrove Partners LLC
- Led a six-week technical SEO engagement for a fee-only NYC financial advisory firm on WordPress, cutting pages Google crawled but declined to index from 112 to 73.
- Consolidated nine competing AMT and ISO articles (2,556 impressions, zero clicks) into two authoritative guides with seven 301 redirects, sitemap cleanup, and re-indexing.
- Cut the booking page's total blocking time from 8.1s to 2.4s and layout shift from 0.106 to 0.008 by deferring the third-party scheduling widget until after page load.
- Removed the render-blocking stylesheet across all 228 pages by pruning unused theme features and generating per-page critical CSS, verified by a full-site scan.
- Timed every page on the site to isolate the remaining bottleneck to the host's 1.8s cold response and 5-minute cache window; the resulting host fix brought median response to 41ms.
- Built a site-wide opportunity map from a full 230-page crawl and 90 days of Search Console data: 11 title and meta rewrites, 14 merge clusters with named survivors, and 47 pages to retire.
- Wired the Calendly booking event into Google Tag Manager so booked calls are counted as conversions and attributable to the article that produced them.
- Fixed duplicate JSON-LD structured data across five templates, a stale-sitemap caching fault, and two broken legacy redirects, and left the client runbooks plus a self-serve consolidation playbook.
Back-end Engineer
Longevity Acupuncture, INC.
- Audited a TypeScript, Node.js, and Azure healthcare platform within the first week of the engagement and delivered a written technical assessment and re-baseline to the CEO.
- Reproduced reported clinical scoring-accuracy defects by running the complete automated test suite against the deployed release and isolating the specific failing cases.
- Reviewed Azure App Service and PostgreSQL configuration, authentication, and tenant isolation for a patient-data system, then delivered a prioritized security remediation plan.
- Built a bottom-up delivery estimate across seven workstreams with four costed scope tiers, from 450 to 1,170 hours, so that leadership could weigh scope against budget.
- Verified TLS enforcement, audit logging, and field-level encryption against HIPAA-oriented requirements, documenting which items were met and which remained open.
- Analyzed git history and the CI/CD workflow to pinpoint release-process gaps, and recommended test gates, staging, and monitoring to keep regressions out of production.
- Delivered an engineering assessment the CEO described as excellent, with every finding reproducible and clearly separated into confirmed results and open questions.
Senior Engineering Consultant
Aragon AI
- Scoped, architected, and delivered Notion AI publisher end to end, a Notion-to-production content pipeline with back-end APIs, job orchestration, and AST-driven config insertion, removing engineering from the content-release critical path.
- Partnered with design and growth to redesign top-of-funnel surfaces, including a navigation bar, full login revamp with responsive product-showcase carousel and i18n, flagship landing pages, and 6+ supporting pages driving SEO and conversion.
- Owned payment and platform reliability across Stripe, Paddle, and Loops. Introduced checkout retry logic, resolved a production idempotency race condition, and routed critical failures to dedicated alerting.
- Led a site-wide SEO and structured-data overhaul. Normalized JSON-LD schema across all pages, fixed robots.txt rules unblocking headshot subpage indexing, and shipped noindex and llms.txt updates.
- Designed the notifications panel as a JSON-driven source of truth and shipped 15+ in-product changelog entries plus 20+ photo-editor tool configurations, creating a repeatable release-communication surface.
- Drove performance, QA, and DX improvements. Compressed oversized media, retired stale A/B code paths, hardened generate and onboarding flows, and authored the team's CLAUDE.md and .cursorrules baseline.
Co-founder and CTO
MyStoryBookAI
- Founded and led an AI-powered platform that generates personalized children's storybooks, growing it to hundreds of paying customers.
- Architected the full system, including the Next.js front end, serverless APIs, a GPU cluster on RunPod with ComfyUI for image generation, and Cloudflare R2 for scalable asset storage.
- Designed distributed workflow orchestration with round-robin GPU scheduling, deterministic pipelines, and caching to ensure reproducibility at scale.
- Integrated LangChain-powered features to expand simple user inputs into rich story templates, improving personalization while reducing customer effort.
- Drove end-to-end business execution, including Shopify integration, print-on-demand fulfillment pilots, and SEO and marketing initiatives.
Senior Software Engineer
Hatica
- Integrated 8+ developer tools, including Azure DevOps, ClickUp, AWS CodePipeline, and Bitbucket, driving 30% revenue growth and landing enterprise clients like 1mg, Truecaller, and Hotstar.
- Led back-end migrations from repository-based to service-based metrics and Elasticsearch to SQL, executing with zero downtime across a production system serving enterprise customers.
- Architected event-driven processing pipelines using Temporal workflows and idempotent handlers, replacing pull-based systems and improving reliability at scale.
- Designed onboarding dashboards that reduced customer setup time from 7 days to 1 day, significantly improving adoption rates.
- Built monitoring and logging pipelines using New Relic and established on-call protocols, reducing incident resolution time from 3 days to 1 day.
- Led TypeScript adoption across the codebase and mentored engineers in a Sequoia Surge–backed 9-person team as a founding engineer.
Software Engineer
Tekion
- Developed and optimized UI components for Tekion's Automotive Retail Cloud (ARC), improving user experience and core product functionality across the dealer-facing platform.
- Completed 170+ tickets with an average resolution time of 2.3 days, delivering features including NPS survey enhancements, audit logs, and performance optimizations for customer service order requests.
- Spearheaded multi-site functionality implementation in repair order sales and reports, boosting operational efficiency for multi-location dealerships.
- Collaborated closely with product managers, team leads, and QA to ship high-quality deliverables aligned with business goals.
Software Engineer
Deqode
- Architected and implemented a blockchain monitoring system, achieving over 99.9% efficiency, using Redis-based job scheduling with a fast and robust queue mechanism.
- Wrote unit and end-to-end tests across the project, increasing development velocity and reducing regressions.
- Built a training automation app that automated the entire onboarding and training process for new employees in small and medium-sized companies.
