Zelalem Y.

Top Rated full-stack engineer with $20K+ earned on Upwork and 5+ years building production SaaS products. I work mainly with Python/Django/FastAPI, React/Next.js/TypeScript, Node.js, PostgreSQL, APIs, and AI-powered product features. I’m usually brought in for one of three situations: building a SaaS product from MVP to production, taking over an existing codebase and shipping features safely, or adding integrations and AI workflows to a live system. WHAT I WORK ON • SaaS & Full-Stack Development Production web applications, dashboards, admin tools, multi-tenant platforms, and internal systems. • Backend & APIs Python, Django, Django REST Framework, FastAPI, Node.js, REST APIs, GraphQL, authentication, RBAC, webhooks, and background jobs. • Frontend React, Next.js, TypeScript, and responsive product interfaces. • Data & Infrastructure PostgreSQL, Redis, Docker, CI/CD, GCP/AWS, deployment, monitoring, and performance optimization. • AI Product Features LLM/API integrations, structured outputs, document and data extraction, workflow automation, and human-review flows. • Existing Systems Debugging, refactoring, third-party integrations, migrations, production fixes, and performance improvements. PRODUCT EXPERIENCE Financial and bookkeeping systems, AI-powered research and funding platforms, travel and social products, SaaS applications, and automation-heavy workflows. I’m comfortable joining an established engineering team or owning a feature end-to-end, from requirements and architecture through implementation, testing, and deployment. I communicate clearly, flag blockers early, and keep progress updates concise. If you have a SaaS product that needs new features, backend/API work, AI integrations, or help stabilizing an existing system, send me the stack and the problem you’re trying to solve.
