I am a Computer Science and Engineering graduate from IIT Guwahati, class of 2026. I have a strong background in algorithmic problem solving and competitive programming, holding a Codeforces Expert rating of 1803 as well as top global ranks on LeetCode and CodeChef. On the practical side, I love building low-level systems and backend tools. Some of my favorite projects include Sastran, a crash-safe key-value and vector storage engine built from scratch in Rust, and Coherence, an open-source project that uses graph structures to keep AI agent memories consistent. I also built Redrob, a data pipeline that can filter and rank 100,000 profiles on a basic CPU in less than five minutes by spotting structural fraud

Tokenless is our entry for Track 1. It handles a wide range of tasks while spending as few Fireworks tokens as possible. The idea is simple. Not every task needs a paid model, so we do the work locally whenever we can, and only call a Fireworks model when we really have to. The agent runs as smalll Gemma model, Gemma 3 4B, inside the container using llama.cpp on CPU. When a task arrives, we first classify it with plain rules that cost nothing. Math and logic problems are handled by having the model write a short Python program that we run and check, so the answer is proven instead of guessed. Code tasks are generated locally and compiled to make sure they actually work. Everyday language tasks like sentiment, summarization, named entity recognition, and factual questions are answered directly by the local model. Because every one of these answers is produced inside the container, they count as zero tokens under the hackathon rules. That puts us in the best possible spot on the leaderboard, which ranks passing teams by how few tokens they use. If a local answer is ever missing, the agent can fall back to a Fireworks model, but in practice it almost never needs to.
