You will get Node.js/Golang REST API built to scale
Top Rated
Project details
If you need a backend API that handles real load without breaking, I will design and build reliable, high-load RESTful APIs using NestJS (Node.js/TypeScript) or Go (Golang) with PostgreSQL.
What is included:
✅ Core API Development: A robust, fully-typed REST API built for complete CRUD operations, user management, and seamless data flow.
✅ Advanced Engineering: Complex data modeling and relational queries optimized for speed and efficiency. Proper schema design, indexing, and migrations with PostgreSQL.
✅ Strict Security: Implementation of standard security protocols, including JWT authentication, rate limiting, and input sanitization to protect your application.
✅ Scalable Architecture (Standard/Advanced Tiers): Performance-critical optimizations to ensure your API handles high concurrency without failing.
✅ Production-Ready Operations (Advanced Tier): Asynchronous background job processing (RabbitMQ/Kafka) for computationally expensive tasks and full Docker-ready deployment configuration.
I provide a senior-level perspective on all backend engineering, drawing from past experiences building platforms that process 50,000+ weekly records and real-time data pipelines.

Web Vitals & PageSpeed Optimization Expert Needed for Next.js Site
Rasul did a fantastic job on Goldrate.com, including setting up the Hetzner instance and completing the site coding. He was responsive, clear in his communication, and delivered solid work on time. I’d happily hire him again.

NodeJS, NextJS, TypeScript - Website Redevelopment
Rasul was instrumental in my website's redevelopment. He rebuilt my 6 year old WordPress and mass plugin-dependent platform from WordPress to Next.js (Node.js + TypeScript) with real-time metals/FX API integration, ISR/SSR backed by Redis caching, and Dockerized deployments. He implemented i18n routing with hreflang/canonical best practices, dynamic sitemaps, structured data, and consent-aware analytics all while vastly improving Core Web Vitals and reducing ongoing site overhead costs. Communication was clear, all deadlines were met, and the quality of his codebase was impeccable. Rasul is a kind, highly intelligent, proactive, solution-first engineer who owns outcomes. I would not hesitate to hire him again (I've been working with him for multiple years now).
