    des rangila

    march 2026 — april 2026

    600 people toured india at a night market, stamping a digital passport at every stall they visited. the software was the only thing nobody had to think about.

    pulsar hunting

    april 2025 — may 2025

    pulsars — dead stars sweeping a beam past earth hundreds of times a second — are rare enough in telescope data that a model scores well by never finding one. so i made fake ones until it had enough to learn from.

    codivate

    2020 — 2022

    moocs scale but don't know you; tutoring knows you but doesn't scale. i led engineering on the thing in between: a platform spanning ten chapters across three countries, reaching 3,500 students, national press coverage. all in high school!

employment

  1. amazon web services

    sde intern · may 2025 — august 2025 · seattle, wa

    updating a database usually means taking it offline, and at 10,000+ clusters that adds up to a lot of unhappy enterprises. i built the rolling update system that moves through nodes in batches, so the service keeps serving through its own upgrades.

  2. peraton labs

    swe intern · june 2024 — august 2024 · basking ridge, nj

    models deployed on edge hardware go stale as conditions change, and there's no sending data back to a datacenter to fix that. i built the pipeline that retrains them in place, on live sensor, terrain, and weather feeds.

  3. seq technology

    swe intern · may 2023 — august 2023 · new york, ny

    getting an answer out of a data warehouse means knowing its schema and writing the sql, so business teams end up waiting on analysts. i built the layer that takes the question in plain english and writes the query — and gets better every time someone corrects it.
