Software developer building thoughtful digital experiences.

I build fast, scalable web applications with React, Node.js, and modern JavaScript technologies.

About Me

I'm Keshav Tiwari, a software developer focused on building modern web applications. I work across the frontend and backend, turning ideas into responsive interfaces, APIs, and production-ready systems.

I've grown through three roles at the same company — from intern to graduate engineer to full-time professional — gaining hands-on experience with production development, debugging, deployment, automation, and maintenance.

Full-Stack Engineering

React, Node.js, and databases — building scalable systems end-to-end

Backend & APIs

Node.js, Express, and MongoDB — building reliable APIs and data models

AI Integration

OCR pipelines, LLM automation, and intelligent product features

Systems Thinking

DSA, system design, and performance-first architecture

Selected Work

Built for people, shaped by systems.

E-Commerce Performance Optimization

E-Commerce Performance Optimization

"Turning a slow storefront into a fast, reliable checkout experience."

Problem

Poor Core Web Vitals — including a slow Largest Contentful Paint — were driving 40% cart abandonment at checkout.

Solution

Rebuilt the Next.js image pipeline with lazy-loading, optimized the production build, and streamlined the checkout flow to cut load time.

Impact

Improved LCP by 35% • Reduced cart abandonment to 18% • 28% increase in conversions

Manufacturing Data Intelligence

Manufacturing Data Intelligence

"Real-time production visibility across 5 factories — zero spreadsheets."

Problem

Production metrics across 5 factories were tracked manually, with no real-time visibility into performance or downtime.

Solution

Built a Node.js backend with WebSocket streaming and a React dashboard for live KPI visualization across all 5 facilities.

Impact

Real-time visibility into 50+ metrics • Reduced downtime detection time by 85%

Internal AI Assistant

Internal AI Assistant

"Knowledge at the speed of thought."

Problem

Engineering team was wasting hours on documentation lookup and repetitive tasks.

Solution

Built an LLM-powered assistant using the OpenAI API with Pinecone-based knowledge-base indexing for fast semantic search over internal docs.

Impact

Reduced lookup time by 80% • Shipped features 15% faster
