Yashwant Bezawada

Software engineer working on applied AI.

I'm a software engineer at FedEx, working on generative AI: chat assistants, retrieval systems and the pipelines that deploy them. Outside work I fix bugs in open-source machine-learning and systems libraries, and build side projects with AI coding agents, where tests and review decide what stays.

open source

Fixes merged upstream, newest first.

  1. # huggingface/transformers Tokenizers shared one model_input_names list across instances, so changing it on one tokenizer silently changed every other one of that class. #42051
  2. # vllm-project/vllm CUDA-graph replay skipped the wait in layer-wise KV-cache loading, so attention could read cache data before it had arrived; those setups now fall back to piecewise graphs. #31057
  3. # lballabio/QuantLib GsrProcessCore kept references to its input arrays, so the temporaries common in the Python bindings left them dangling and path generation crashed; it now keeps copies. #2410
  4. # jax-ml/jax jnp.arange with a non-zero start was folded into a constant array, which made compile times blow up for large ranges; it now builds the range from iota. #33602

side projects

Built for fun and learning.

  • snapwire.io A file becomes a stream of codes on one screen and is read by another device's camera: no network, no server, no accounts.

  • morp.ai Code maintenance by AI agents: keeping a codebase secure and current without changing what it does. Not open yet.

  • remixpdf.com PDF tools in the browser: merge, split, sign and redact, where redaction deletes the marked text from the file instead of covering it.

  • devtoolkit.io Formatters, converters and encoders for developers, most of which run entirely in the browser.

  • removebackgrounds.ai Background removal: drop in an image and get a transparent cut-out back.

  • planwright.ai A planning tool for AI-built software: it breaks an idea into tasks that agents and people can carry out. Not open yet.
