01.About Me
I'm a Senior Software Engineer with over a decade of experience building high-performance web and mobile applications across Ad-Tech, E-Commerce, SaaS, and EdTech industries. Currently at Shopsense AI, where I architect serverless systems on AWS handling 150K+ daily ad impressions.
My expertise spans the full stack - from crafting pixel-perfect React interfaces to designing cloud infrastructure with AWS CDK, Lambda, and DynamoDB. I've led teams, built design systems used by 40+ engineers, and consistently delivered measurable performance improvements (60% CWV boost, 20%+ engagement increase).
I use AI as a force multiplier - not a crutch. It helps me ship 3x faster while maintaining code quality I can defend in any review. This portfolio was built with AI assistance, and every line is production grade.

03.Where I've Worked
Senior Software Engineer
Shopsense AI
- Led Embed Generator from zero to launch, Shopsense’s first publisher embed commerce product, now on 10 publisher sites with 150K+ daily impressions at 0.5% CTR. Partnered with Sales and publisher dev teams to onboard partners and get them live quickly.
- Architected the AWS serverless platform using AWS CDK and Infrastructure as Code (IaC). Developed APIs exposing Jarvis AI capabilities for Images, Articles, and Product Lookup, powering five embed types and the page injector deployed across partner websites.
- Helped steer Shoppability after Embed Generator by applying embed patterns to the React admin, 5 embed types, per-publisher branding, and async jobs that cut onboarding from days to a few clicks in the dashboard.
- Designed and implemented Shopsense's first A/B testing platform, including experiment tracking and analytics, enabling the team to validate product decisions with real user data.
- Scaled the codebase in a Turborepo monorepo with shared types, review/reprocess workflows, and analytics dashboards, with GitHub Actions CI/CD across preview, staging, and production.
Senior Frontend Engineer

- Worked on invoice and AR (split-pane views, batches, email tracking) and support tickets on company/contact pages, plus a support module with rich email templates in TinyMCE.
- Introduced frontend patterns on a 4,000+ file codebase: lazy TanStack Router routes, shared form and table components, React Hook Form + Zod, query cache persistence, and Sentry.

How This Portfolio Was Built
This portfolio is itself a technical showcase — a Turborepo monorepo with two Next.js apps, server-side AI chat, and edge-cached performance.
Built with AI Assistance
I used AI tools (Cursor + Claude) to accelerate development of this portfolio — architecture design, code generation, and content optimization. Every decision was validated, every line was reviewed. AI is my co-pilot, not my autopilot.
