Sr. Engineer, AI Compilers

Tenstorrent AI ULC (2025-present)

Contributed to the design and implementation of MLIR-based AI compilers for Tenstorrent hardware, such as blackhole and wormhole using C++20 and Python:

• Pushed the generality of the compiler and added support in the optimizer for more operators and graphs. This automation resulted in significant reduction in developers' time.
• Worked on ttnn-jit frontend and made it pip install-able for easier usage.
• Developed graph-based approaches for generating ttnn IR from a decorated python function to be used in ttnn-jit. This added support for TMs and reduction ops, as well as dynamically decomposing composite ops.

Software Engineer

Huawei Technologies Canada Co., Ltd (2023-2025)

Contributed to the design and implementation of AI compilers tailored for Huawei's hardware platforms.

• Developed an end-to-end solution integrating MLIR with TVM, leveraging MLIR's optimization passes specifically optimized for Huawei hardware, alongside TVM's auto-scheduling.
• Designed new MLIR dialects compatible with MLIR's Tosa and TVM's Relax dialects, and implemented lowering passes for these dialects.
• Led a team of engineers to design and implement an end-to-end testing infrastructure, enabling validation of multiple flows with automated C code inference capabilities using C++, Python, Shell scr.

Engaged in the development of FPGA CAD tools using C++20 for Place and Route team:

• Conducted thorough research to identify cutting-edge EDA algorithms tailored to support custom architectures, and developed multiple algorithms focusing on core routing, parallel scheduling and filter generation, leading to a notable 12x acceleration in router flow through the implementation of parallel techniques.
• Designed the complete clock solution for the tool, achieving a significant 16x speed enhancement compared to the previous solution for placing and routing on the clock network.
• Collaborated closely with the Timing team to pioneer advancements in clock skew optimization and the resolution of hold violations, resulting in a noteworthy 5\% increase in fmax.

Junior Software Engineer

Virtual Reality Lab, K.N.Toosi University (2015-2016)

• Developed a Java framework for optimizing the movement of virtual cars in curved highways and bridges using Bezier curve fitting methods.
