Surya Singh — Data Engineer in Los Angeles, CA

Data engineer with 5+ years across ETL, data architecture, and BI — now building the agentic layer on top: Claude agents and skills, LangChain pipelines, and AI workflows that turn weeks of data onboarding into days.

At Oliver Wight I build agentic data tooling: Claude-based skills that let business advisors query client data directly, an agent pipeline that categorizes incoming client data, runs the ETL, and flags quality issues with human-in-the-loop review (client onboarding went from weeks to days), and a LangChain + AgentScope help bot with persistent cross-session memory.

Before that, three years at Infosys: Spotfire dashboards over SQL/Oracle/Redshift serving 10,000+ daily users, 500+ reports migrated off legacy systems with Python and REST automation, and two Rising Star awards along the way.

Nights and weekends I ship products end to end — UniversalShelter.org (a universal-housing platform: Supabase, Netlify, Cloudflare, PayPal, mail and Google APIs), HabiCard (web, Chrome extension, iOS), and GymShot (React Native) — and I'm comfortable all the way down to the shell, the compiler, and the microcontroller.

Experience

Data Engineer, Oliver Wight (dec 2024 – present)

• Claude-based AI skills that let business advisors query and interpret client data directly, reducing reliance on manual analyst support.
• Claude agent/skills pipeline that categorizes incoming client data, runs the ETL to populate the product's data model, and flags quality issues through human-in-the-loop review — client onboarding cut from weeks to days.
• Agentic Gemini workflow that curates a business's data hierarchy per IBP/S&OP practices and generates an interactive demand/supply/resource dashboard you can alter in natural language.
• In-app help bot on LangChain + AgentScope with persistent cross-session user memory, so answers personalize over time.
• End-to-end ETL infrastructure from scratch: Microsoft Fabric, Apache Airflow, SQL Server, PostgreSQL.

Data Engineer, Infosys (jan 2022 – dec 2024)

• Spotfire dashboards over SQL, Oracle, and Redshift serving 10,000+ daily users across departments — a 30% increase in data-driven decision making.
• Migrated 500+ reports from legacy systems using custom Python workflows and REST automation.
• Deployed Spotfire on AWS, cutting data retrieval times 25%.
• Discrepancy-detection dashboard in IronPython and R for real-time validation during a data warehouse migration — 35% better discrepancy checks.
• Two Infosys Rising Star awards (2023, 2024) — for leading a migration that cut costs 20%, and for client relationship management.

ETL Developer, Infosys (apr 2021 – dec 2021)

• HabiCard — Habit tracking that lives where you already are: web dashboard, Chrome new-tab extension, and iOS.
• cc-fleet — Every Claude Code session on your machine as a pixel blob pet on your desktop — hops when it needs you, sleeps when it's done.
• GymShot — Daily body-progress-photo app where small pods of friends keep each other accountable.
• Ship Management System — Booking and maintenance system for ship schedules, reservations, and crews.
• OCR Equation Solver — Reads math equations off the screen with OCR, evaluates them, and clicks the right answer.
• RShell — A Unix-style shell written in C++ from fork() up.
• SketchBoard — An Etch-a-Sketch built on an AVR microcontroller.
• Data Analysis Portfolio — EDA and modeling of US county-level election and COVID data.
