Riya Tilwani

I build product systems across backend, full-stack, AI workflows, and technical leadership for startup teams that need senior ownership from ambiguous requirements to production systems.

Stealth startupGryd.ioStockXOla ElectricAmadeusLumentis AI

Senior engineering for teams that need product judgment and hands-on delivery.

I’m useful when the work crosses backend systems, product constraints, AI workflows, integrations, and the messy decisions that sit between idea and shipped software.

AI product engineering

Designing and shipping AI-backed product workflows where model output has to become reliable, editable, and useful inside a real business process.

Problem framing, data boundaries, evaluation loops, human review, reliability, and rollout

Backend-heavy product work

Owning APIs, databases, checkout flows, payment integrations, subscriptions, document generation, dashboards, and deployment pipelines.

Data modelling, API boundaries, queues, payments, observability, deployment, and scale

Senior execution for startups

Turning incomplete product direction into shippable systems, reviewing architecture, managing developers, and making pragmatic build decisions.

Architecture reviews, tradeoff calls, team coordination, delivery planning, and hands-on implementation

A full-time foundation across marketplaces, EV product systems, travel tech, AI products, and startups.

A chronological view of the roles behind the work: global marketplace systems, payments, travel technology, fractional leadership, and recent AI/product builds.

Major systems, launches, and AI product work I have owned.

Selected work across marketplace backend systems, AI SaaS delivery, startup technical leadership, EV launch systems, and current creator tooling.

StockX global marketplace backend systems

Built and operated checkout and pricing microservices for StockX's global marketplace, contributing to backend systems behind a platform that surpassed 50M+ lifetime trades, 15M+ buyers, and 1.7M sellers by 2023.

The marketplace backend had to support high traffic, pricing and checkout correctness, asynchronous workflows, deployment safety, regulatory constraints, and fraud-risk considerations across production services.

Worked across Go, Node.js, PostgreSQL, DynamoDB, Kafka, SQS, AWS, Kubernetes, CircleCI, Harness, and Datadog while building reliability and domain depth in global marketplace operations.

Ola Electric launch-period customer systems

Built customer-facing web and backend systems during Ola Electric's high-demand EV launch period, including official website work, Adyen/PayU payments, and scheduled/on-demand test-ride workflows.

The launch cycle saw 100k+ bookings in 24 hours and about 500k first-month bookings, so customer-facing flows needed to handle demand while supporting payments, booking workflows, and service deployments.

Worked across React, Node.js, Java Spring Boot, MySQL, Jenkins, Marathon, Mesos, and Azure, while also leading external contractors, interviewing, and mentoring new joiners.

CaseStealth startupRoleFounding engineerAreaCreator tooling dev platform

AI-powered creator widget platform

Developing an AI-powered dev platform for creator widgets, focused on turning AI-processed SVG and Lottie assets into reusable interactive units through a pipeline-driven ingestion flow.

The product needs a large library of creator-ready widgets, but building each widget manually would be slow, repetitive, and hard to scale while the product direction is still evolving.

Own the platform architecture and full-stack implementation for a pipeline that reduces manual widget-building effort and gives the team a faster path from generated assets to usable creator tooling.

A growing set of experiments and reusable engineering pieces.

I’m adding more public work over time, especially around AI-native development, agent workflows, and full-stack foundations.

Best fit for startups and lean teams that need senior momentum.

I’m most useful when the scope is technical, ambiguous, and important enough to need an engineer who can reason through tradeoffs and still ship.

Good fit

  • Fractional CTO or technical leadership for small teams
  • AI workflow automation and production integrations
  • Technical consultation for architecture, delivery, and hiring
