Aman Sutariya

Senior Full-Stack Engineer & Fintech Architect | 10+ Years Experience

I help businesses build production-grade systems that handle millions of dollars in transactions and millions of users. I am not just a coder; I am a Lead Engineer who specializes in turning complex business requirements into scalable, secure, and high-performance software.

With over a decade of experience across Fintech, Web3, and Consumer SaaS, I bring a unique blend of "move fast" startup energy and "break nothing" enterprise reliability.

Why Clients Hire Me:

1. Deep Fintech & Web3 Expertise: At Fin3, I architected the "Blockchain Integration System" (BIS) that connects US commercial banks to permissioned blockchains. I built the rails that allow regulated institutions to settle fiat payments 24/7/365. I understand the rigorous security, compliance (KYC/AML), and consistency standards required when handling real money. If you need someone to build a secure payment flow or a robust settlement engine, I have done it at the highest level.
2. High-Performance Frontend Engineering: At LottieFiles, I engineered the core rendering technology used by millions of designers worldwide. I optimized complex vector animations to run at 60fps on low-end devices, rewriting rendering pipelines and managing heavy client-side state. I don’t just build UIs; I build performant applications that respect your user’s battery life and data plan.
3. Modern Full-Stack Fluency: I am equally comfortable in the frontend and backend. My core stack includes:

• Frontend: React, Next.js, TypeScript, Tailwind CSS (Pixel-perfect execution).
• Backend: Node.js, Python (FastAPI), NestJS, PostgreSQL, Supabase.
• Infrastructure: AWS (Lambda, ECS), Docker, CI/CD pipelines.

AI-Augmented Development: I leverage cutting-edge AI tools (LLM agents, RAG pipelines) to accelerate development. I use these tools to automate testing, generate documentation, and refactor legacy code, allowing me to deliver features 2x faster than traditional developers without compromising quality.

How I Work: I am a remote-native engineer who values asynchronous communication and autonomy. I document my work obsessively, ensuring that you are never left with "black box" code. Whether you need an MVP launched in 30 days or a legacy system re-architected for scale, I deliver code that is clean, tested, and built to last.

Let's build something world-class together.
