Helixis
a persistent memory layer for AI agents — recalls, pinned context, and tool history so language models can hold longer threads of attention across sessions.

Mathew.
a noteproduct + engineering for AI agents. I write software, take photographs, and assemble small FPV drones from parts. mostly I'm curious about how systems hold attention — both the software kind and the human kind.

engineer based in Kochi. two years into product engineering, focused on how AI agents hold context across sessions.
Started on Java and HTML/CSS in school, then settled into the React + TypeScript stack through college projects. The substance was always in the late-night side builds, not the syllabus.
Interned at Tata Elxsi on autonomous-driving simulation — collision detection on CARLA + OpenMaps, OTA progress tracking for infotainment firmware. Then 1 year 4 months as a Software Development Engineer at White Rabbit Labs in Kochi: Angular 20 + NgRx applications with 100+ concurrent components, FastAPI microservices, OAuth2 QuickBooks integration with HMAC-secured webhooks, and a Notion-style real-time state layer that cut API calls by 80%.
Now at YE Stack in a hybrid product + engineering role, building Helixis — a persistent memory layer for AI agents — and broader systems that map how human cognition actually works.

what I've shipped.
four projects I've put real time into — an AI memory layer, an agent-friendly web architecture, a microfinance tool for Kerala, and a launch-tracking app.04 of 12 shown

Agentic Website
an architecture that lets sites expose page-specific tools through llms.txt — browser agents invoke them directly, no DOM parsing.

Kshree
a loan management app for Kudumbashree members — Kerala's women-led microfinance network. tracks group repayments, savings, and disbursal cycles.

Astrofilo
a real-time rocket launch tracker — every mission in one place, push alerts for ISS passes, and background sync that cuts network calls by 60%.

after the rains.
a slow, ongoing series shot mostly between deploys — canals in Fort Kochi, tea estates in Munnar, monsoon afternoons. I post one or two a month to glass.photo.
drones · FPVbuilding, not just flying
learning to fly slowly.
I build my own 5-inch FPV drones from parts — soldering ESCs, flashing PX4, dialling in PID. flying is the least of it; the joy is in the build, the crash, the rebuild.
