Dawit S.

I join your product team to ship features, resolve bugs, and maintain your SaaS over the long term. From an unfinished prototype to a live application, I take ownership of development and stay involved as your roadmap grows. I’m a Top Rated Plus full-stack developer with 100% Job Success. I work across React/Next.js, Node.js, Python/FastAPI, databases, and cloud deployment. If you have an AI-built prototype, an existing codebase that needs attention, or a backlog growing faster than your team can deliver, I can help. I learn your application, agree on priorities, and work through improvements in manageable releases. My experience includes: • Meta API integration for a Node/Next.js SaaS: authorization flows, permission checks, token-refresh workers, advertising analytics, and brand–creator partnership functionality. • An ongoing healthcare-platform engagement using FastAPI, Google Cloud, and Flutter, with responsibilities covering backend performance, security, and third-party integrations. • A completed Vercel-to-VPS migration engagement covering Docker, Nginx/SSL, and CI/CD, followed by additional AWS troubleshooting and documentation contracts with the same client. What I take on: • Frontend features and complete user workflows. • Backend APIs, database changes, authentication, and permissions. • Third-party integrations, payments, and AI-powered features. • Debugging across frontend, backend, and infrastructure. • Deployment improvements, ongoing maintenance, and new releases. How I work: I review the existing implementation before estimating changes. We agree on scope and acceptance criteria, then work through focused releases. I send progress updates that separate completed work, test results, blockers, and next steps. I flag scope changes before expanding the work and document technical decisions as the product evolves. My core stack: React, Next.js, TypeScript, Node.js, Python, FastAPI, PostgreSQL, Supabase, AWS, and Google Cloud. I’m looking for a long-term collaboration, ideally 40+ hours per week. We can start with a focused feature or repair, then continue into ongoing development and maintenance. Tell me about your product, its current stack, and the priorities you want me to own.
