How can we collaborate to fulfill all of your business requirements? Regards Navrinder Singh

build production React, NextJS and ThreeJS applications for startups and SaaS companies - the kind of products that need to scale past the MVP, handle real users, and still feel fast a year later. 7+ years in commercial JavaScript engineering, with a focus on complex frontend architecture, real-time systems, and immersive 3D web experiences. Most of my work falls into three areas: 𝗦𝗮𝗮𝗦 𝗮𝗻𝗱 𝗽𝗿𝗼𝗱𝘂𝗰𝘁 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴. React and NextJS platforms with proper architecture - typed end-to-end with TypeScript, structured state (Redux Toolkit, Zustand, TanStack Query), and a backend that won't fall apart at 10k users. NodeJS, NestJS, ExpressJS, PostgreSQL, MongoDB, GraphQL, REST, Prisma, Drizzle. Auth done right (JWT, OAuth, SSO, RBAC), payments that don't lose money (Stripe, Stripe Connect, webhooks with proper idempotency). 𝗥𝗲𝗮𝗹-𝘁𝗶𝗺𝗲 𝗮𝗻𝗱 𝗱𝗮𝘁𝗮-𝗵𝗲𝗮𝘃𝘆 𝗮𝗽𝗽𝘀. WebRTC, WebSockets, live dashboards, collaborative editing, streaming AI chat interfaces. Trading and FinTech UIs with thousands of moving data points. Interactive visualization with D3, Recharts, Visx. Streaming LLM responses from OpenAI and Anthropic Claude, vector search with Pinecone and pgvector, RAG pipelines. 𝗧𝗵𝗿𝗲𝗲𝗝𝗦 𝗮𝗻𝗱 𝗪𝗲𝗯𝗚𝗟 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲𝘀. 3D product configurators, immersive landing pages, data-driven 3D scenes. React Three Fiber, Drei, custom GLSL shaders, performance tuning to hit 60fps on mid-range hardware. The kind of work that ends up on Awwwards, not in a tutorial. 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝘀𝘁𝗮𝗰𝗸 Frontend - React, NextJS (App and Pages Router), TypeScript, React Native, Redux Toolkit, Redux-Saga, Zustand, TanStack Query, Jotai, Tailwind CSS, Material UI, shadcn, Radix UI, Framer Motion, GSAP, Vite, Turbopack. 3D and graphics - ThreeJS, React Three Fiber, WebGL, GLSL shaders, Drei, immersive UI, interactive 3D. Backend - NodeJS, NestJS, ExpressJS, Fastify, GraphQL (Apollo), tRPC, REST, WebSockets, Server-Sent Events. Data - PostgreSQL, MongoDB, Redis, DynamoDB, Prisma, Drizzle, Mongoose. Cloud and infrastructure - AWS (Lambda, Cognito, DynamoDB, S3, CloudWatch, API Gateway, EC2), Docker, Kubernetes, Vercel, Cloudflare Workers, GitHub Actions, Sentry. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I think about your product, not just your tickets. If something in the spec is going to hurt you in six months, you'll hear about it before I start. I write code other engineers can read without context, ship on the timeline I commit to, and don't disappear mid-project. Communication is direct and frequent - no surprises at delivery. Comfortable working across US, EU and APAC timezones, on long engagements where the bar for architecture and code quality is high. 𝗕𝗲𝘀𝘁 𝗳𝗶𝘁 𝗳𝗼𝗿 B2B and vertical SaaS platforms. AI products that need serious UX (streaming chat, agent dashboards, internal tools). ThreeJS and WebGL projects where the visual quality actually matters. FinTech and trading interfaces. Real-time collaboration apps. Long-term engagements where you want an engineer who owns outcomes, not someone waiting for the next ticket. 𝗟𝗲𝘁'𝘀 𝘁𝗮𝗹𝗸 Send me a short message with what you're building, your current stack, and rough timeline. I'll respond within 12 hours with honest thoughts on fit and approach - and if I'm not the right person, I'll usually point you toward someone who is.

With 14 years in full-stack engineering and system design, 6 years in AWS Solutions Architecture, and 10 years in leadership, I have built dozens of technically successful apps, often from scratch, alone or in teams. My experience spans a wide range of development, from fast MVPs to giant modular monoliths and event-driven microservices. I have successfully transformed legacy systems into modern, scalable, and robust systems, developed high-load solutions from scratch, and created custom frameworks, front-end and back-end component libraries, and SDKs. I have mentored and led teams to success. By making good technology choices and establishing proper processes, I have improved the performance of entire projects by up to 300%. I am passionate about my work and will genuinely love your projects as my own, with great attention to detail and focus on the goals of your business. COMPANIES TRUST Workato.com, All4Labels.com, Chingari.io, Shastic.com, Zirtue.com PEOPLE SAY “His expertise in complex system design and AWS solutions was crucial in addressing multiple use cases. Alexandr's ability to deliver scalable, secure, and efficient systems makes him an invaluable asset. Highly recommended.” — Juergen Koehler | All4Labels “When I think of Aleksandr, one word comes into my head - overqualified. And I mean that in a good way when that's not a problem but a solution.” — Dmitry Matora | SalesLyft, All4Labels “I had the pleasure of working with Aleksandr on an exciting [open source] project and he exceeded all my expectations” — William Reiske | BlueHive, Medical Informatics Engineering I BELIEVE - Only architects who code and developers who architect can truly excel in either field. - Architecture is not about building software in the most complex and sophisticated way. It is about making the correct choices in the given context. - Often, communication and teamwork are more important than technical skills. - Leading the software project is more than knowing where to go and how to get there. - Competence can be replaced with AI. Today, you have to bring more than that. - Remote work can be more efficient than on-site.
