Senior Full-Stack / Platform Engineer and Tech Lead / Architect-Implementer with 18+ years of industry experience, including 4+ years in technical leadership roles, spanning architecture, hands-on engineering, and DevOps. Operating at Staff-level scope across architecture, hands-on engineering, and cross-team technical leadership. A cross-role, cross-stack engineer combining deep execution with product thinking and system- level architecture — consistently delivering high-impact results, owning systems end-to-end from code to infrastructure, CI/CD, and production operations, and ensuring features deliver real customer value, are adopted, and fit naturally within the product. Specialize in rescuing, modernizing, and scaling complex brownfield or legacy systems, applying incremental modernization strategies (e.g., Strangler Fig pattern) and evolving them into maintainable, high-performance architectures using modular monolith, microservices, and event-driven approaches.

Building environments where engineers take ownership, move fast, and solve real problems — with room for creativity, initiative, and technical exploration.

Processes are shaped to fit the business and product — not copied from “FAANG playbooks” without context. AI-first engineer, using AI as a force multiplier while maintaining strict control over architecture, performance, security, and system integrity.

Need an AI web app or SaaS MVP shipped fast, without rework later? I build production software that stays easy to change as load grows. Clean React fronts. Dependable Node.js APIs. RAG that answers from your data. I'm Shweta Dubey, a Senior Full-Stack AI Engineer with 8.3+ years. I've taken products from sketch to launch. HyROI and a custom timesheet platform went from ideas to deployed systems under my lead. I handled UX flows, the React front end, secure API contracts, and the data layer. On the front end I ship fast, accessible React with TypeScript. Reusable components and sane state. Server data fetching where it helps performance. On the backend I build Node.js REST services with clear contracts. Pagination, auth, rate limits, and query tuning baked in. Optional GraphQL when it adds value. For AI features I integrate OpenAI with LangChain. Chat assistants and document Q&A. Summarization as needed. RAG over PDFs and internal wikis so answers are grounded. I set up embeddings and retrieval, plus eval dashboards so you can watch outputs and improve them. Multi tenant setups supported, tenant data stays isolated. Infra stays predictable on AWS with Docker. Kubernetes when the workload calls for it. Data on PostgreSQL or MongoDB with migrations and tuning. CI/CD from repo to production. What I can help with: - SaaS MVPs in React and Node.js, with auth and billing. Dashboards and settings, role based access. - AI chat and Q&A using OpenAI plus LangChain. RAG over PDFs and Google Drive. Internal KB support. - Backend REST APIs. Versioned endpoints, pagination, rate limits, caching, webhooks. - Internal tools and admin portals in React with TypeScript. - Data modeling and performance tuning on PostgreSQL or MongoDB. - CI/CD pipelines to AWS with Docker and Kubernetes. Observability, alerts, logs. How I work: - Discovery call and scope, then a clear plan. - Prototype or API spec in 48 to 72 hours. - Milestones with weekly demos and progress notes. - Clean Git history. Small PRs with review checks. - Testing matched to risk, API tests and unit tests where they pay off. - Handover docs and runbooks. Short video walkthrough. - Jira for tracking, async updates as needed. I work 25 to 30 hours per week, IST. US and EU overlap, plus UK hours where needed. Open to a 3 to 5 day pilot.

Clients include a $1M+/month fashion DTC brand, a $500K+/month industrial brand, and multi-seven-figure operators across beauty, food & beverage, sports, and health in the US, UK, Canada, and Australia. Top Rated Plus · 98% JSS · Top 3% Shopify talent on Upwork · CXL Certified · Shopify Partner · Klaviyo Certified If any of this sounds familiar: Your Shopify store gets traffic but your conversion rate hasn't moved in months You've changed themes, installed apps, and hired developers still not converting You're scaling ad spend but ROAS is declining because the store isn't doing its job Your email list is large but generating less than 20% of revenue You've had a CRO audit a PDF with no implementation, no follow-through, no results You want someone who tells you what to build and why, not just someone who executes ...then we're probably a good fit. Launching or rebuilding your Shopify store: A store that looks like a template loses the customer before they've read a single headline. I build from research up customer profiles, competitor analysis, and Figma design before a line of Liquid is written. The result is a Shopify store engineered to convert from day one not a theme with your products dropped in. CRO for a Shopify store already running traffic: Flat conversion rates and rising CPAs trace back to one root cause - a gap between what your ads promise and what your store delivers. I run a full-funnel CRO system across your homepage, PDPs, cart, and checkout. Every decision is built from your actual GA4 and heatmap data - not best practices borrowed from another brand. Klaviyo flows and retention run alongside - fixing the funnel without fixing retention leaves half the revenue behind. Recent Results Fashion DTC, $1M+/mo - Shopify Plus CRO redesign. Full brand rebuild. Sign boards brand, $500K+/mo - Shopify build + CRO strategy. Ongoing partnership. Beauty DTC, $265K/mo - CVR 1.3% → 3.9% in 90 days. Email $24K → $73K/month. Zero ad spend increase. Food & Beverage, $80K/mo - 6-month retainer. CVR 1.6% → 2.7%. AOV $47 → $62. 14 of 23 tests positive. Client renewed. Sports DTC - Mobile A/B test. +41% CVR uplift. Estimated $87K annual revenue impact. Fashion brand, $75K/mo - Full-funnel audit + $10K+ CRO redesign. Outcome: Highly Successful.
