(or sortira)

student research engineer (interpretability and alignment)

interests: reasoning models, RL, synthetic data, local and edge ai

currently research intern at AI4Bharat (visual reasoning, multimodal multilingual interp). previously ai engineer intern at Sarvam AI — built the eval framework for an NVIDIA lipsync model + modularized the dubbing pipeline (video).

hobbies: discussing tech, sports and games with friends, playing computer games, going on city walks. if you're in calcutta by chance, reach out and we can meet!

writing silicognition.is-a.dev my technical blog on solo research projects, encounters with ai.

experience

  1. [mar 2026 - present] research intern @ AI4Bharat — circuit tracing for reasoning problems posed in various modalities across model sizes, languages for various SoTA open models.
  2. [aug 2025 - dec 2025] ai engineer intern @ Sarvam AI — eval framework for NVIDIA lipsync; detected and fixed 500% file size increase in lip-sync model output; modularized dubbing pipeline; a/b tests on prompt structures

solo research projects

  1. forgeformer — hand-designed 2-layer transformer that adds two-digit numbers; no gradient descent. demonstrated transformer internals in a model designed with interpretable weights from ground-up.
    [writeup] · [demo]
  2. seven deadly sins of gemma — steering vectors per sin in gemma-2-2b; verified the vectors via steering examples and activation patch analysis. [writeup]
  3. some of the works done with other orgs are not publishable.
