7 years building production AI infrastructure — MCP agents, RAG pipelines, distributed backends, and full-stack systems that ship at scale.
Six production systems — each with a distinct constraint, a deliberate architecture, and a measurable outcome.
Client work and independent builds shipped outside of full-time roles.
Legal & financial services marketplace connecting users with verified lawyers and CAs — booking system, WhatsApp notifications, multi-role auth (User / Expert / Admin), AI document processing.
Full-stack home decor e-commerce platform — OTP auth, product catalog, cart & checkout, shipping integration, and automated GST invoice generation.
Manufacturing P&L and costing tool for edible oil production — tracks raw seed input, oil/khari yield, overhead allocation, and per-unit profitability across pack sizes.
Real estate plot management app for tier-3 Indian cities — prevents double-booking conflicts and provides real-time plot availability visibility for developers and sales teams.
Three companies, six years, measurable outcomes at every step.
Kartikey played a key role in building and improving the UI using React.js, consistently delivering clean, responsive, and user-friendly interfaces. He has a strong understanding of component-based architecture and pays close attention to performance and usability. Alongside frontend work, he is well-versed in Node.js and contributed effectively to backend integrations, APIs, and business logic. Kartikey's ability to work across the stack makes him a reliable and versatile engineer.
He is proactive, takes initiative, and consistently delivers high-quality work across both frontend and backend. Kartikey communicates clearly and works well with others, making collaboration smooth in a fast-paced environment. He takes ownership of his work and is reliable when it comes to execution and follow-through.
Six principles that shape every system I build — accumulated over six years of production engineering.
Five layers I own end-to-end. Every tool here is battle-tested in production.
I started writing production code at FIS Global in 2019 — building automation frameworks and ETL pipelines that handled financial-scale data at an enterprise with zero tolerance for error. That early constraint shaped how I think: instrument everything, fail gracefully, ship with confidence.
At Bestpeers, I led a 3-engineer team shipping a healthcare monitoring platform across React web, React Native mobile, and a custom smartwatch tracking heart rate, SpO2, and GPS — all from a single Node.js backend. I learned that clean architecture isn't aesthetic, it's operational: it's what lets you ship three surfaces without tripling the maintenance burden.
At Evren, I own the technical architecture — an AI support chatbot on Groq Llama 3.3, MCP agents, agentic workflows, and the customer-facing Admin Portal for enterprise OS management. I set technical direction, lead cross-functional engineering decisions, and mentor developers through code reviews and system design. The AI here is invisible infrastructure, not a UI feature bolted on.
Open to full-time remote roles, contract work, and conversations about hard technical problems. If you need someone who ships production AI systems end-to-end — let's talk.
