Key Metrics & Approach

• 100+ projects delivered | 0 deadline misses | 100% satisfaction rate
• Maintained strong async communication and rapid iteration loops across 6 different time zones
• End-to-end product ownership: from foundational system design and Figma wireframing to full production deployment and CI/CD setup

Key Achievements

• Building the entire product from scratch — Next.js 14 frontend, Rust-based processing backend, LLM orchestration layer, and Kubernetes-hosted infrastructure on GKE.
• Developing a proprietary RAG pipeline with Pinecone + OpenAI embeddings for codebase-aware AI suggestions aimed at reducing hallucination rates.
• Implementing early core features by rapidly iterating on AI integrations (GPT-4o + Claude) focusing on establishing a solid architectural foundation.
• Preparing monetization systems — integrating Stripe, billing dashboard, and subscription lifecycle management end-to-end for future launch.

Responsibilities

• Setting technical direction and architecture for all product engineering
• Managing cloud infrastructure architecture and scaling strategy on GCP/GKE
• Planning direct engagement strategies for early customers and product discovery
• Open-sourcing internal tooling for developer communities

Key Achievements

• Architected and delivered a real-time notification system using WebSockets + Redis Pub/Sub, reducing user perception of data latency by 70%. Handles 800k+ events/day with 99.97% uptime.
• Migrated 6 REST microservices to GraphQL — reduced over-fetching, cut average API payload size by 48%, improved client developer velocity.
• Built an internal dashboarding platform (React + Recharts + D3.js) used by 4 product teams for real-time KPI monitoring — replaced 3 separate Looker dashboards.
• Implemented zero-downtime blue-green deployments on AWS ECS using Terraform, enabling weekly releases vs previous monthly cadence.
• Reduced PostgreSQL query P99 latency from 820ms → 90ms by introducing partial indexes, query plan analysis, and connection pooling (PgBouncer).

Responsibilities

• Owned end-to-end delivery of 4 major product features — from RFC writing through production deployment
• Led architecture discussions and ADR documentation for platform decisions
• Mentored 3 junior engineers through weekly 1:1s and paired code reviews
• Maintained observability stack: Datadog APM, structured logging, custom alerting
• Collaborated with Product and Design on roadmap estimation and UX trade-offs

Key Achievements

• Shipped the real-time collaborative editing system using CRDTs, supporting simultaneous edits across 10,000+ concurrent users
• Built Linear's universal search using Tantivy (Rust full-text search), achieving sub-30ms queries on datasets of 1M+ issues
• Rewrote the Electron app bundling pipeline, shrinking the app binary from 340MB to 89MB
• Implemented the cycle planning interface with drag-and-drop, keyboard shortcuts, and undo/redo history

Key Achievements

• Built the ArcDev design system — 40+ reusable components (React + Storybook + Jest) that became the foundation for 3 separate products, reducing design-to-code time by 55%.
• Reduced initial bundle size by 42% via code splitting, lazy loading, and tree shaking, improving LCP from 4.2s → 2.4s.
• Led migration from class components to React Hooks — converted 180+ components across 2 codebases with zero production regressions.
• Integrated 3 third-party REST APIs (Stripe, Twilio, Intercom), building reusable service wrappers tested to 98% coverage.

Responsibilities

• Developed responsive, accessible UI components using React 17, Redux Toolkit, and CSS Modules
• Collaborated with design team using Figma, translating complex designs into interactive interfaces
• Performed code reviews and pair programming sessions with backend engineers
• Maintained automated test coverage using Jest and React Testing Library
• Participated in bi-weekly sprint planning and retrospectives (Jira/Scrum)
