SUMMARY
Frontend developer with 4+ years of continuous full-time experience across React/Next.js and Angular, delivered
through outsourcing/staff-augmentation engagements spanning fintech, SaaS, AI products, and ecommerce for
EU/US clients. Took ownership of architecture-level decisions (state management, SSR strategy, performance
budgets) on individual client projects — covering rendering performance, bundle optimization, and payment
integrations. Open to a long-term, product-focused role where that depth of ownership can build over time on a single
codebase.

EXPERIENCE
Frontend Developer (React / Next.js)
256 Devs — Remote (outsourcing / staff augmentation, multiple client projects) | Mar 2023 – Present
• Owned architecture decisions (state management, SSR strategy) on select client projects and helped shape
codebase practices adopted more broadly across the team.
• Refactored render-critical components and reduced render-blocking resources, improving Lighthouse scores on
key product pages.
• Migrated a legacy SPA to Next.js with SSR/SSG, reducing initial load time and improving organic search visibility,
tracked through Core Web Vitals reporting.
• Reduced shipped JS on key routes by combining route-based code splitting, dynamic (lazy-loaded) imports, and
stricter chunk boundaries; paired with HTTP/client-side caching (TanStack Query) and responsive images/srcset
with lightweight placeholders.
• Brought Cursor and Claude into the day-to-day workflow and helped formalize reusable patterns across the
React/TypeScript codebase, contributing to faster turnaround on routine feature tickets.
• Set up end-to-end event tracking with GA4 and Tag Manager, giving the product team visibility into the conversion
funnel.

Frontend Developer (React / Angular)
MIF Projects — Remote (outsourcing agency, 6 client engagements across industries) | Mar 2022 – Mar 2023
• Delivered across 6 production platforms spanning different industries (SaaS, fintech, insurance, legal-tech AI,
automotive marketplace, ERP/CRM); each engagement meant owning a feature end-to-end, building cross-domain
depth in state management, performance work, and payment systems.
• Implemented and tested merchant/payment gateway integrations for a fintech client's checkout flow, with no
production incidents tied to that code in the following year.
• Built an admin panel for product/content management so the content team could handle catalog updates
themselves instead of routing everything through dev tickets.
• Integrated a streaming (SSE) AI chat into an existing codebase, handling safe rendering with DOMPurify to close
off XSS risk, with no security issues reported after launch.
• Architected an Angular marketplace (2,000+ listings, 50+ filters) on Angular Universal with RxJS-based state
management, keeping PageSpeed consistently in a healthy range across recurring audits.
• Built a virtualized data table for an ERP/CRM system (5,000+ rows, 15+ filter types) backed by Jest unit tests,
improving test coverage and reducing defects.

• Set up CI/CD pipelines with GitHub Actions across three environments (Vercel/AWS/Nginx), standardizing
deployment and reducing manual steps.
