Hire the Best React.js Developers in Chennai, IN

Most Upwork developers will accept your job, write the code you asked for, and disappear when something breaks at scale. I do the opposite. I'm a Lead DevOps & SaaS Architect, founder of Asynx Devs, and I work with companies that need their tech to actually hold up under pressure - not just look like it does on the demo call. When you hire me, you communicate directly with the lead architect. No account managers, no Slack handoffs to junior devs. I architect the system. My in-house team executes under my direct technical oversight. What I specialize in: 🔹 DevOps & Cloud Infrastructure - Kubernetes (k3s, bare-metal), Docker, CI/CD pipelines, multi-tenant deployments on AWS, GCP, and Azure. I've cut clients' cloud bills by 60%+ by replacing bloated managed services with optimized setups. 🔹 System Architecture & Backend - Node.js / TypeScript microservices, event-driven systems, real-time IoT-to-web pipelines. I build single-source-of-truth configs that bridge hardware and software teams. 🔹 AI Integration at Scale - I've taken enterprise Next.js AI apps from a 15-second "wait of death" down to under 3 seconds while maintaining 100% EU data residency compliance. Recent work: ✅ Architected a multi-tenant IoT manufacturing platform with strict Row Level Security - real-time hardware sync to a Next.js dashboard, zero data leaks across tenants. ✅ Built a custom Unified Config Engine that auto-generates C headers and TypeScript files from a single JSON source - used daily by hardware and software teams. ✅ Audited and rebuilt an enterprise AI SaaS architecture, dropping LLM response latency from 10-15 seconds to under 3 - without breaking GDPR compliance. How I work: → Architecture first, code second. I'll send you a clear technical plan before writing a single line. → Honest communication. If your idea won't scale, I'll tell you - and propose three alternatives. → Long-term maintainability. I build it as if I'll be maintaining it 5 years from now (because I might be). → No buzzwords, no fake metrics, no overselling. You'll like working with me if: You need someone who owns the architecture, not just the tickets You've been burned by a freelancer who disappeared after delivery You care about security, compliance, and not burning your runway on bloated infra If your Upwork shortlist has 20 profiles that all look the same - invite me. One 30 minute call will make the difference clear.

Zoho Advanced Partner + Catalyst Partner + Creator Certified Expert. I help businesses solve operational problems by combining Zoho's 50+ apps with custom development — AI agents, AWS, React portals, Catalyst serverless. 8+ yrs, 250+ implementations. ═══ WHY CLIENTS HIRE ME ═══ Most Zoho freelancers configure software. I architect business systems. The difference shows up in your P&L. If you've ever heard "Zoho can't do that" — you've been talking to the wrong consultant. Zoho's templates handle 70% of what most businesses need. The other 30% — the part that actually drives revenue and saves hours — needs custom code. That's where I live. ═══ CREDENTIALS ═══ ✔ Zoho Advanced Partner (official partner tier) ✔ Zoho Catalyst Partner (rare — Zoho's serverless platform) ✔ Zoho Creator Certified Expert ✔ 8+ years, 250+ Zoho implementations ✔ 100% Job Success Score on Upwork ✔ $100K+ Upwork earnings, 4,000+ hours ✔ Founder of Elite Tech Corporation (Upwork agency, 5,471 hrs, 100% JSS) ═══ WHAT I BUILD ═══ ▸ Zoho One full implementations for $5M–$50M revenue companies ▸ Salesforce / HubSpot / Monday → Zoho migrations ▸ Zoho Catalyst serverless apps and microservices ▸ Custom React / Next.js portals on top of Zoho APIs ▸ AI agents on Zoho (Claude / OpenAI via Zoho MCP server) ▸ Zoho + n8n / Make automation pipelines ▸ Zoho FSM field service deployments with mobile + dispatch ▸ Zoho ↔ AWS Lambda / API Gateway / S3 middleware ▸ HIPAA-compliant Zoho for healthcare ▸ Zoho ↔ QuickBooks / NetSuite / SAP integrations ═══ HOW I WORK ═══ 1. Discovery: 30-min call to map your actual business problem (not just "we need Zoho") 2. Architecture: I design the Zoho + custom layer in writing before any code 3. Build: I personally lead architecture and senior code; my vetted team at Elite Tech Corporation handles parallel execution on larger scopes 4. Train + document: your team owns the system after I leave 5. Optimize: optional retainer for ongoing improvements ═══ TWO WAYS TO WORK WITH ME ═══ ▸ Direct senior engagement at $50–60/hr — best for architecture, audits, AI integration, complex Catalyst work, fractional Solutions Architect retainers, and 1–2 person scopes. ▸ Team delivery via Elite Tech Corporation (my Upwork agency) at $20/hr blended — best for full Zoho One implementations, migrations, and parallel-workstream scopes where multiple specialists work in parallel under my architecture. Tell me your problem; I'll recommend the right model. ═══ INDUSTRIES I KNOW WELL ═══ Real Estate · Field Service / Manufacturing · Professional Services (legal, agencies, consulting) · E-commerce · Healthcare (HIPAA-compliant) · Insurance · Education ═══ STACK ═══ Zoho One · Zoho CRM · Zoho Creator · Zoho Catalyst · Zoho Books · Zoho FSM · Zoho Analytics · Zoho Flow · Zoho Desk · Zoho People · Zoho Inventory · Deluge · REST API · OpenAI · Anthropic Claude · MCP · n8n · Make · React · Next.js · Node.js · AWS Lambda · S3 · API Gateway · Twilio · Stripe · QuickBooks API · Salesforce → Zoho migration ═══ NEXT STEP ═══ Send me a brief description of your project — current pain, what you've tried, what success looks like. I'll respond within 4 hours with whether I'm a fit and what an engagement would look like. If you'd rather start with a paid 30-min architecture call, see my "Zoho Health Check & Optimization Roadmap" in my Project Catalog below. I respond to every message. I don't take projects I can't deliver cleanly.
