Hire the Best SaaS Developers

Full Stack Developer with 6+ years building production SaaS platforms, booking systems, CRM tools, and AI-integrated applications, end-to-end, from React/Next.js frontends, Nest.js/Node.js/FastAPI backend to the AWS infrastructure they run on. Recent work: → Leading full-stack architecture at Bingo Labs — owning cloud infrastructure, AI automation workflows, and the full product delivery cycle → Built multi-tenant SaaS CRM with RBAC, Stripe billing, and AWS-hosted infrastructure serving 200+ tenants from MVP to production → Delivered booking systems, real-time dashboards, and AI-integrated apps using LangChain, LangGraph, Claude, and OpenAI APIs → Designed and shipped CI/CD pipelines, Docker/Kubernetes deployments, and GitHub Actions workflows from scratch I'm not a developer who's "familiar with AWS" — I architect and operate it professionally. 9 AWS certifications (Solutions Architect, Developer, ML Engineer, Data Engineer, CloudOps) and 2 Oracle Cloud credentials mean I provision ECS clusters, write CloudFormation, wire Lambda pipelines, and run Terraform without a separate DevOps hire. What I build for clients: → Multi-tenant SaaS platforms with RBAC, real-time dashboards, and drag-and-drop customisation (ReactJS, NextJS) → Scalable REST APIs and microservices (NestJS, Express.js, FastAPI, Django) → High-performance Next.js frontends — Core Web Vitals, SSR/ISR, code splitting → AI-integrated apps: LangChain, LangGraph, OpenAI, Claude APIs → Payment systems: Stripe Connect, Razorpay, Khalti, eSewa → React Native mobile apps (iOS & Android) → Data engineering and ML pipelines (SageMaker, TensorFlow, Keras) Core stack: TypeScript · React · Next.js · NestJS · Node.js · Python · PostgreSQL · MongoDB · Redis · AWS · Docker · Kubernetes · Terraform If you need someone who owns the whole stack — not just a single layer — send me a message. I usually reply within a few hours. — — — — — — — — — — Full stack developer for SaaS platforms, booking systems, CRM tools, and AI applications.

Founder of thegemstech | SaaS Architect | Full Stack Product Engineer | AI & Scalable System Specialist I help startups, founders, and businesses build scalable digital products designed for real-world growth — not just demo-level applications. Most developers can build features. Very few understand how to build systems that survive real business operations, scaling challenges, performance pressure, and future expansion. That’s where I specialize. I’m a Full Stack Developer with strong experience in: • React.js / Next.js • Node.js / Express.js • MERN Stack • PostgreSQL / MongoDB • SaaS Architecture • AI Integrations • REST APIs • Real-time Systems • Scalable Backend Infrastructure I’ve worked on production-level platforms including: • RestroCash — Restaurant & Hospitality SaaS Platform • GreenMove — Transport & Booking System • AI-powered CMS Platforms • Marketplace & Multi-tenant Systems • Real-time Dashboard Applications My approach is business-first and architecture-first. Before development starts, I focus on: • Scalability • System architecture • Database structure • Performance optimization • Long-term maintainability This helps clients avoid expensive rebuilds and technical debt later. I value clean code, strong communication, reliable execution, and long-term collaboration. If you're building a serious product and need someone who understands both technology and business systems, let’s connect. — Lokendra B. Jargha Founder, thegemstech

I build production-ready web apps, SaaS platforms, dashboards, and AI-powered workflows using React, Next.js, TypeScript, Node.js, Python, PostgreSQL, MongoDB, Supabase, and API integrations. I have 8+ years of experience across frontend, backend, dashboards, automation, scraping/data pipelines, payment/API integrations, and cloud-based product development. I can take a feature from requirements to architecture, implementation, testing, deployment, and long-term maintenance. What I can help you build: • SaaS MVPs and admin dashboards • React / Next.js frontend applications • Backend APIs and business logic • AI/LLM integrations using OpenAI, Gemini, or similar providers • Data dashboards, reporting systems, and analytics views • MongoDB, PostgreSQL, Supabase, and REST API integrations • Scraping, automation, and async data-processing workflows • Bug fixes, refactoring, performance improvements, and production support Recent project examples include: • Codexia — an AI software memory platform that analyzes GitHub pull requests, extracts engineering decisions, stores project memory, and powers a grounded RAG-style chat experience. • Personal Expense Tracker — a full personal finance dashboard with budgeting, analytics, transaction history, reporting, and export-focused workflows. • ImmiHub — a web platform built with clean frontend architecture, responsive UI, and practical user-facing flows. I’m a good fit if you need someone who can own full-stack features end-to-end, communicate clearly, estimate realistically, and build maintainable software instead of quick patches.
