About

Hi, I’m Swati Modi, a Software Engineer 👩‍💻, passionate about products and a maker at heart 🚀

I like figuring things out 🕵️‍♀️, Side projects are my love language, and there is usually something half-working on my laptop that I am weirdly excited about 😬.

• Last9 (last9.io) [Jun 2022 – Mar 2024]
  Time-Series Data Warehouse - Levitate (Link)
  Worked closely with the CTO and a small team to scale Levitate, a real-time time-series warehouse processing over 1 trillion samples monthly. Designed and implemented ingestion pipelines for both metrics (1.5B time-series/min) and events (400M/min), real-time materialized views using streaming aggregation, and a metric cardinality limiter for usage-based billing and resource optimization. Also led development of a custom alerting engine powered by complex PromQL queries.

• Delhivery (delhivery.com) [Mar 2021 – May 2022]
  Logistics SaaS - OS1 (Link)
  Developed OS1, a logistics SaaS platform used by Delhivery to optimize supply chain processes. Worked on improving the system’s scalability and reliability to support high-volume logistics operations.

• Fynd (fynd.com) [Oct 2019 – Mar 2021]
  Virtual Makeup & Face Filters SaaS SDK - Glamar (Link)
  Built Glamar, a virtual makeup and Snapchat-like face filter SDK. Developed a facial landmark stabilization system and image segmentation tools for hair color, makeup, nail art, and face filters, ensuring real-time performance and cross-platform compatibility.

Consulting Experience — Founded Helix Software Services 👩‍💼 Link to heading

I lead a small, sharp engineering team at Helix Software Services. We partner with startups and growing companies to build, optimize, and ship reliable tech—especially where speed, cost, and real-world performance matter. My personal focus lies in backend systems and distributed infrastructure, with hands-on experience in both low-latency, high-throughput backend work and practical machine learning deployments.

Here’s a glimpse of what we’ve worked on 🛠️ :

• Real-time Background Removal
  Built an on-device background removal system that runs smoothly at 30FPS on mid-range phones—no server required. Integrated into video tools for seamless, efficient virtual presence.

• On-Device Fitness Pose Tracking
  Delivered a real-time pose correction system used in yoga and physiotherapy apps. Lightweight, fast, and designed to run offline on mobile devices.

• Hand-Tracking Performance Improvements
  Solved latency spikes in MediaPipe’s iOS pipeline, making hand-tracking snappy and production-ready for gesture-based apps.

• Backend Scaling for a Unified Search Platform
  Stabilized and optimized backend infrastructure for a personal search tool that indexes content across cloud drives, emails, and bookmarks—cut infra costs and boosted response times. Focused on distributed service design, caching layers, and data indexing strategies.

• SEO and Frontend Optimization
  Improved page load speeds and search engine visibility for several client apps through focused, no-fluff performance work.

What we don’t do 🙈🙉🙊 Link to heading

• Backend systems that look shiny in docs but cry under load 😭
• “AI solutions” that need a supercomputer to say hello 🥵
• Research that lives its best life… in a PDF 🎭

We are hands-on builders who care more about what works than what sounds fancy. Clean infra, fast code, and getting things to run where they actually need to run, whether it’s shaving latency, squeezing models onto devices, or making backend systems cheaper and more reliable.

Tech I have worked-on/specialize-in or find interesting so far 🤓 🧐 Link to heading

• Distributed systems
• On-device ML
• WebAssembly and AR

I strongly believe in end-to-end productivity and having a holistic product vision than just ticking feature boxes.

I like reading books, both fiction and non-fiction 💫 🕵️‍♀️ 📚, and writing about tech @swati-modi and blog.

I enjoy running, biking, lifting things, cooking healthy, and pretending to meditate. 🏃‍♀️ 👩‍🍳 🧘‍♀️
