  PDI
  PDI is a library that aims to decouple high-performance simulation codes from input/output issues.
  It offers a declarative application programming interface that allows codes to expose the buffers where they store data
  and notify PDI about important simulation steps. It supports a plugin system to provide existing libraries such as HDF5,
  SIONlib, or FTI to codes. FTI is made available to codes, potentially mixed in a single execution.
  This approach allows describing I/O operations in a dedicated YAML file instead of interleaving them with simulation
  code. Dedicating YAML to describe I/O operations improves their portability and maintainability.
  PDIC
  PDIC is a clang compiler plugin that allows C/C++ developers to add pragmas to C/C++ structures directly in production
  code.
  This enables the pdic compiler to extract declarations from the Abstract Syntax Tree (AST) of structures through static
  code introspection and then transcribe the structure compositions into a chosen file format, YAML in this case. This
  solution is distributed through a C/C++ library, a binary with clang dependencies, and is also available with a Python 3
  wrapper.

  Role in the Project: Compiler Engineer
  • Topic: Cloud Architecture
  Industry Sector
  Aqemia is a pharmaceutical company with drug discovery pipelines. The mission is to expand the drug discovery
  process by combining quantum-inspired physics and machine learning.
  Project / Objectives / Responsibilities
  Control the computation cost on cloud instances. Continuous Integration and Continuous Deployment (CI/CD).
  Redesign of the data processing pipeline and storage system architecture:
  • From text file storage to parquet format.
  • Unification of the Python cloud storage system.
  • Create a Python wrapper for chemistry simulation tools (library and binary) to accelerate the calculation process.
  Standardize the calculation processes and storage formats used. Control computation costs on cloud instances. Continuous Integration and Continuous Deployment (CI/CD).
  pysmina
  A fork of AutoDock Vina customized to better support the development of scoring functions and high-performance
  energy minimization. smina is maintained by David Koes at the University of Pittsburgh and is not directly affiliated with
  the AutoDock project. Pysmina is a fork of smina and customized with Python Boost to support Python operations. It is
  easier to use in a Python environment.
  pyDockRMSD
  DockRMSD is capable of deterministically identifying the minimum RMSD corrected for symmetry and can do so without a significant loss of computational efficiency compared to other methods. The open-source DockRMSD program
  can be easily integrated into various docking pipelines to facilitate accurate atomic mapping and RMSD calculations,
  which can help improve docking performance, especially for ligand molecules with complicated structural symmetry.
