Front-end OR Back-end developer needed for Mobile application + Future website + application work. Skilled, but lacked proper approach to understanding the company's processes, notably around expectations of communication. Repetitive asks and repeated direction on company approach was often negated, dismissed, or ignored.

Want to scale your SaaS product without hitting architectural bottlenecks or burning through cloud budgets?

I partner with tech startups and fast-growing businesses to architect, build, and launch production-ready SaaS applications. With 5+ years of specialized experience deploying robust web applications, I ensure your product launches faster, scales seamlessly, and remains highly secure.

As a Senior Full-Stack Developer, my primary focus is turning complex product roadmaps into clean, maintainable infrastructure using React, TypeScript, and Node.js.

HOW I ACCELERATE YOUR SaaS LAUNCH & GROWTH:

Senior-Level Architecture: I don’t just write code; I design systems. I build highly typed, predictable front-ends using React/TypeScript paired with bulletproof, modular back-ends via Node.js (NestJS/Express) and PostgreSQL/MongoDB.

Accelerated Time-to-Market: By implementing automated CI/CD pipelines (Docker, AWS, GitHub Actions), I consistently cut client deployment times by 40%+, getting your MVP into users' hands faster.

Enterprise-Grade Security: I secure your business and users from day one using row-level security (RLS) in PostgreSQL and robust authentication protocols (Auth0, JWT, AWS Cognito).

CORE TECHNICAL SPECIALIZATION:

Frontend: React, TypeScript, Next.js, Redux Toolkit, TailwindCSS

Backend & Architecture: Node.js, NestJS, Express.js, RESTful APIs, GraphQL

Databases & ORMs: PostgreSQL/Supabase/Neon (Row-Level Security), MongoDB, TypeORM, Prisma

Cloud & DevOps: AWS (EC2, Lambda, S3), Docker, CI/CD Pipelines, Vercel

Let’s build an elite technical foundation for your SaaS. Click the "Message" or "Invite" button to discuss your product roadmap.
