This is an advanced undergraduate course. The course covered both the front end and back end of Compilers, focusing on Program analysis and Optimization. As the lead TA, I helped the professor design the course content. I also created the programming assignments in the LLVM framework. Every week, I held a two-hour recitation session (a parallel to a regular lecture) to discuss the practical problems we designed for programming assignments. Such assignment problems included AST analysis, data type analysis from AST, Control/Data flow analysis, Dead code elimination, etc.

This was a third-year undergraduate course on "Introduction to Formal Languages and Compilers". I taught

• Basics of formal languages - Finite Automata, Regular Languages, Context Free Grammars, Push Down Automata, Turing machine.
• Basics of Compilers - Lexical Analyzer, Syntax Analyzer, Abstract Syntax Tree, Code Generation, Three address code.

This is the practical lab session for Compilers. I taught how to build a compiler using different tools i.e., Lex, Yacc, etc.

This is an introductory undergraduate course. In this course, I taught the basics of digital systems, how to design them. In particular, I taught how to translate boolean logic into digital circuits and compute based on the clock signal. A case study of a digital system with a booth multiplier. In addition to these, I taught how to build a 4-bit microprocessor from scratch, the basics of instructions, different cycles in instruction execution, translate instruction to machine code, and design a processor for following the instruction code.

In this lab, I demonstrated several case studies of Digital systems. These include Four-bit binary adders with carry, Booth Multiplier, and a four-bit processor design. We simulated these with p-spice. Students had to submit a term project to develop an exciting system with real-life usages in this course. I supervised about ten such projects.

I worked in the BigCode team at Facebook, to design models for understanding source code changes. In particular, we designed a model which learns to reason about source code Diffs from millions of code changes submitted to the code base.

I worked in Google Cloud security team, where I helped develop technique for detecting Phishing attempt through Google Drive documents. I worked with textual analysis (static component), and sandboxed system behavior (dynamic component) for analyzing the documents.

In this internship, I had a hands-on experience with practical program repair tool (Elixir). A major challenge in Program Repair is the localization of the fault. I developed a tool for improving such fault localization using different information available to the developer. Most prominent of such information is the bug report corresponding to the fault.

I mainly worked as a part time research-consultant in Fin-tech. We developed techniques for analyzing Value-at-risk and way for portfolio optimizations.

I worked here as a Junior Software Engineer. This company is a payment solution provider, and as an engineer here, I worked in contact-less payment (NFC based) payment client. In addition, I also worked in programming the payment chip based card. I implemented Visa and Mastercard specification for payment processing in KSL's contact-less payment processing pipeline.
