Rajni S.

I build and run the software layer of your business - from fast, reliable WordPress and WooCommerce sites to full-stack web applications and AI agent workflows on modern serverless infrastructure. Principal developer at TechPavitra Labs with a 100% Job Success score on Upwork. I take a barbell approach: deliver commodity-tier web work quickly to earn trust, then bring real value through product engineering and agentic systems that automate your operations. WHAT I BUILD: Web and Commerce WordPress and WooCommerce sites, custom themes and plugins, headless WordPress with Next.js, site migrations, Core Web Vitals hardening, and static marketing sites. Product Engineering Full-stack web apps on serverless infrastructure - dashboards, admin panels, internal tools, and SaaS MVPs with auth, billing, and data. Stack: Next.js 14+, TypeScript, Tailwind, shadcn/ui, Supabase, Neon, Vercel, Cloudflare Pages, Stripe, Resend. AI Agents and Workflow Automation Agentic workflow design for sales triage, support automation, invoice processing, and content ops. RAG pipelines, knowledge bases, and tool-calling layers. Human-in-the-loop guardrails and observability. Stack: LangGraph, n8n, OpenAI, Anthropic, Pinecone, Supabase pgvector, LangSmith. Ongoing Partnership Care retainers, feature drips, Agent Ops (keeping live agents tuned as foundation models evolve), and fractional tech partner engagements. WHY WORK WITH ME: - Principal-led delivery - I do the work, not a subcontractor - AI tooling gives you 2-3x faster turnaround without cutting corners - I understand messy real-world integrations: legacy CRMs, WooCommerce plugin ecosystems, banking and government APIs - I design agent guardrails and compliance layers so your automations do not make expensive mistakes in production - Transparent communication and clear scope on every project
