Shav0 Papoyan

I’m a Lead Full Stack Engineer with 6+ years of commercial experience building production-grade web platforms, AI SaaS products, fintech/payment systems, Web3 products, crypto wallets, and data-driven backend services. I focus on end-to-end delivery—shipping reliable features, designing scalable architectures, and integrating AI/media capabilities responsibly. I enjoy turning complex workflows into maintainable systems through clear task decomposition, observability, and solid testing habits.

At SugarLab, I built and maintained an AI SaaS platform from scratch using Next.js, React, TypeScript, Hono, Prisma, PostgreSQL, Temporal, Docker, LiveKit, and AWS/Vercel infrastructure. I designed a scalable monorepo architecture with Turborepo/Yarn Workspaces, including a web app, back-office app, API server, shared contracts, and workers. I implemented modular backend capabilities for authentication, payments/subscriptions/crypto payments, AI content generation, moderation, creator/affiliate programs, and admin APIs—plus AI/media integrations like OpenAI, Replicate, Together AI, embeddings, pgvector search, and recommendation flows.

I’ve also strengthened product reliability through PostgreSQL/Prisma query optimization, structured logging, and thorough quality practices with Jest, Playwright, and Testing Library. Previously, I delivered Next.js/React applications with SSR/ISR, reusable UI patterns, and reliable data flows—then expanded into real-time experiences with WebSockets and GraphQL. I bring engineering leadership through architecture decisions, mentoring, release planning, and close stakeholder communication.
