Full-Stack Developer | JavaScript | React, Node.js | API Integration

Senior Full-stack developer, 100% Job Success. I build features that work the first time and fix codebases that don't. Stack: Frontend: React, Next.js, TypeScript, JavaScript, HTML, CSS Backend: Node.js, Python, NestJS, Express, REST APIs Database: PostgreSQL, MongoDB, MySQL, Redis Integrations: Stripe, Webhooks, OAuth, API Integration, Third-Party Integrations DevOps: Docker, AWS, CI/CD, Git Industries: SaaS, FinTech, Healthcare, Real Estate, E-commerce, Logistics What I take on: new features, messy codebases that need real fixes not patches, third-party integrations (Stripe, CRMs, anything with an API), database work that holds up at scale, MVPs that ship fast without becoming a mess later. Client feedback: "I would highly recommend Softermii for any programming needs. I am consistently impressed by the quality of the work and team effort brought forth by everyone that we've worked with." — VP of Product, Dollar Shave Club "The team is really flexible with picking up urgent bugs. The prices are very reasonable and they are accessible even over the weekend." — Managing Director, Co-Founder, TempTribe Backed by a senior team at Softermii for larger scope. Send me your project.
