Hire the Best Back-End Developers

I’m a Chicago-based software leader and founder of Gotoinc — a full-stack Talent-as-a-Service agency, focused on Ruby-powered solutions. We work with founders, engineering, and product leaders who need reliable talents, proficient in UI/UX design, front-end engineering, back-end engineering, and DevOps. This is a group of vetted professionals I’ve personally built and led over the years. We help: - Launch and scale Ruby on Rails platforms - Modernize legacy Rails applications - Improve performance and system architecture - Ensure long-term maintenance and reliability - Design a clean, intuitive UI/UX for complex workflows Among our projects: - FinTech platform associated with Growth Hacking creator Sean Ellis.

Long-term collaboration on a healthcare platform operating across multiple US states under strict regulatory and compliance requirements, handling sensitive medical data at scale. - EdTech ecosystem with IPO-level Due Diligence (GNS stock). We worked 7–8 years with GeniusU, supporting the platform through significant Due Diligence processes related to IPO readiness. At one stage, nearly the entire engineering team (except the CTO) was on our side. - IoT cybersecurity product (Product Management & UI/UX). We led product management and UI/UX for a security-focused IoT platform, specializing in complex dashboards, control panels, and data-heavy systems. - Enterprise collaboration with The Access Group (US division). After one of our previous projects was acquired, we were recommended as a key technical provider during the early-stage scaling within a larger enterprise structure. We work through 2 options: - Talents-as-a-Service model. A dedicated expert(-s) on a subscription basis. - Project-Based Collaboration model. We deliver a certain scope or solution in a pre-defined timeline/budget. How to start: 1. Having an intro, where we identify your request 2.

Let's discuss your project. 🔗 Check my portfolio below for live project examples.

I've built production systems serving 100,000+ users and currently lead engineering as CTO of a SaaS platform — so I bring senior-level architecture, not just code. Need a backend or full-stack engineer who ships fast without breaking what already works? I build production NestJS/Node.js APIs, Next.js web apps, and tricky third-party integrations (Stripe, GoHighLevel, Phorest, Zapier, PayFast) that other developers got stuck on. Hi 👋 I'm Rafique — a Top Rated AI-Native Full Stack Engineer with 100% Job Success on Upwork. I have 5+ years of experience building backend services, REST APIs, and SaaS platforms for startups and growing teams. Most of my work falls into one of three buckets: shipping new MVPs quickly, fixing and scaling existing apps, or building the integration layer that connects your product to the tools your business actually runs on. My core stack: 🔧 Backend: Node.js, NestJS, TypeScript, REST APIs, PostgreSQL, MongoDB, Prisma 🎨 Frontend: Next.js, React, TypeScript ☁️ Infra & Tools: AWS (Lambda, Cognito), Vercel, GitHub 🧠 AI-Native Workflow: Claude, Codex, and Cursor — used where they reduce bugs and ship faster, not as a replacement for clean architecture What clients hire me for: ✅ NestJS + Node.js backends with secure authentication and clean REST APIs ✅ Stripe, GoHighLevel, Phorest, PayFast, and Zapier integrations ✅ Next.js full-stack apps (auth, dashboards, SaaS MVPs) ✅ Performance, migrations, and stabilizing existing codebases ✅ Clear estimates, proactive updates, no surprises Recent client feedback: ⭐ "Rafique ROCKS — something I was trying to do on my own for hours and hours, he just did it." — Phorest → GoHighLevel integration ⭐ "Best developer to work with — extremely technical, patient, good communication, and most importantly knows his code. Definitely gonna hire again." — PayFast / Next.js integration ⭐ "He delivered high-quality authentication features, communicated clearly, and was very patient and professional." — NextJS + NestJS auth setup Send me a short message about what you're building or what's broken. I'll reply within 4 hours with a clear plan, realistic timeline, and an honest answer on whether I'm the right fit — no fluff, no sales pitch.

I help startups and businesses build scalable web applications and high-performance APIs. My main focus is backend development, but I also build modern frontend interfaces when needed. With over 3 years of experience, I’ve worked across the full stack designing backend architectures, building APIs, and developing responsive frontend applications. What I Can Help You Build ✔ REST APIs and backend systems ✔ Full-stack web applications ✔ SaaS platforms ✔ Database design and optimization ✔ Third-party integrations ✔ Cloud deployment and CI/CD pipelines Backend Django • FastAPI • Node.js (Express / NestJS) • Laravel Frontend React • Next.js • Vue • Angular Databases PostgreSQL • MySQL • Redis DevOps & Cloud AWS (RDS, S3, Elastic Beanstalk, Lambda) Docker • Linux • CI/CD (GitHub Actions) I focus on writing clean, maintainable code and building systems that are reliable, scalable, and production-ready.
