Back to all posts

Welcome! I’m V Surya Kumar, a Software Development Associate at Goldman Sachs. This blog is where I write about the things I find most interesting in tech — artificial intelligence, software engineering, and systems design.

What to Expect

I’ll be writing about:

• AI & LLMs — inference internals, building agents, training pipelines, and practical applications of large language models
• Software Engineering — architecture patterns, code quality, developer tools, and lessons from building production systems
• Systems Design — distributed systems, infrastructure, performance optimization, and understanding how things work under the hood

Why Write?

Writing helps me think more clearly. If I can explain something in a blog post, I truly understand it. And if someone else finds it useful — even better.

Code Examples

Posts will frequently include real code. Here’s a quick example of what that looks like:

def build_agent(model, tools):
    """A simple agent loop."""
    messages = []
    while True:
        response = model.generate(messages)
        if response.tool_calls:
            for call in response.tool_calls:
                result = tools[call.name](**call.args)
                messages.append(tool_result(call, result))
        else:
            return response.content
