Experience

My Adventures with Large Language Models

https://leanpub.com/adventures-with-llms
Authored a technical book that demystifies how large language models actually work, building up from fundamental blocks all the way to cutting-edge architectures. Unlike resources that lean on theory or implementation alone, it takes a blended, highly visual approach so readers can literally "see" ideas evolve — from vectors to attention, transformers, and efficient training. I owned the entire lifecycle: research, writing, illustration, code implementation, and the design of intuitive explanations aimed at engineers, students, and AI practitioners. The goal was to create one of the most accessible, technically accurate, and practical guides for anyone who wants to understand LLMs from first principles. The book is complete and has earned 50+ organic sales with zero marketing spend, driven entirely by word of mouth and the quality of the material.

MCP Registry & Playground

https://mcps.truefoundry.com
Built a public-facing catalog and interactive playground for Model Context Protocol (MCP) servers on TrueFoundry's AI Gateway. Users browse the catalog, connect their own accounts (Slack, Gmail, GitHub, and more) via OAuth, and call tools through an LLM-powered chat interface. I built the FastAPI backend and the React (Vite + Tailwind) single-page app, plus a GitOps pipeline where each MCP is declared as YAML in-repo and auto-synced to the gateway via tfy apply — GitHub Actions runs a dry-run on every PR and applies on merge. Scaled the registry to 1,368 MCP servers, each with its own config and display metadata, and added OAuth credential rotation for new tenants and production deployment to TrueFoundry clusters. ~114 commits and ~87K lines over three months.

Setu - UPSC Current Affairs & AI MCQ Platform

https://setu.prathameshsaraf.com
Built an EdTech platform that converts daily Indian Express and PIB (Press Information Bureau) current-affairs coverage into exam-ready study material for UPSC aspirants. I designed and built the async FastAPI (Python 3.13) backend end to end: resilient scrapers for both sources with row-by-row fallbacks, and a two-stage LLM pipeline that first classifies each article for relevance, then auto-generates subject- and difficulty-tagged MCQs. Added a retry-stashing mechanism so a database failure never wastes an LLM call — stalled jobs drain automatically on the next run. Secured every endpoint with Google SSO and JWT, shipped an admin ops-and-cost dashboard, and built backfill and daily-cron tooling with A/B model comparison to control quality and spend. Clean layered architecture (controller → service → repository) on PostgreSQL, covered by pytest, with a React + TypeScript frontend.

super-hype: Human-in-the-Loop Employee Advocacy Platform

https://github.com/S1LV3RJ1NX/superHype
Built solo, end to end. super-hype turns a single company announcement into a wave of genuine, on-voice LinkedIn advocacy from the people who actually built the product — no scraping, no shared logins, no bot-style spam. I designed and shipped the full stack: an async FastAPI API with an ARQ background worker (PostgreSQL + Redis) and a React 18 + TypeScript + Tailwind/shadcn frontend. Two workflows — Amplify (a roster engages one existing post) and Distribute (a distinct on-voice post per participant) — with per-persona AI generation tuned to each teammate's voice, a comment-quality floor, and a hard buzzword ban. Every action runs on each member's own consented account through LinkedIn's official API, with Fernet-encrypted tokens, human-in-the-loop approval via web or a bundled Slack DM, randomized publish pacing with daily caps for authenticity, idempotent publishing, campaign controls (pause/resume/reset), roles, a contribution leaderboard, and an append-only audit trail. ~38 commits and ~40K lines in ~3 weeks.

Yukti – LLM-powered Data Intelligence Platform

Yukti is an enterprise-grade platform that enables organizations to interact naturally with their data. It combines retrieval-augmented generation (RAG), advanced vector search, and LLM-driven reasoning to let teams query unstructured and structured data in plain language and receive precise, contextual insights.

Yukti empowers analysts, business leaders, and operations teams to explore documents, reports, and databases without needing technical skills—accelerating decision-making and improving productivity across enterprises.

CARL: Cost-optimized Online Container Placement on VMs Using Adversarial Reinforcement Learning

https://ieeexplore.ieee.org/document/10839070
Containerization has become the standard for deploying applications on public clouds, where enterprises may host hundreds of applications on thousands of containers across numerous VMs. Efficiently placing container workloads onto available VM capacities is a cost-critical and computationally challenging problem, often modeled as a multi-dimensional Vector Bin-Packing Problem (VBP).

We proposed CARL, a novel Adversarial Reinforcement Learning (RL) approach for cost-efficient container placement. CARL mimics the behavior of an offline semi-optimal VBP solver (teacher) while automatically learning a reward function that minimizes VM costs and outperforms the teacher’s performance. It requires minimal historical workload traces and remains resilient to distributional shifts during inference.

We evaluated CARL on large-scale workloads derived from Google and Alibaba traces, placing 5,000-10,000 container requests across 2,000-8,000 VMs. CARL achieved approximately 1,900 placement decisions/sec, delivered approximately 16% lower VM costs than state-of-the-art methods, and maintained robustness under varying resource and workload conditions, demonstrating real-time, scalable efficiency for modern cloud orchestration.

AIME – AI Meeting Intelligence & Analysis Platform

AIME is an AI-powered meeting intelligence platform that records, transcribes, and analyzes sales calls to extract deep insights. It identifies buyer pain points, analyzes personality and sentiment, and generates concise summaries with next-step recommendations.

Leveraging agentic AI workflows, AIME enables sales teams to uncover customer intent, improve communication effectiveness, and close deals faster. The platform’s modular design allows enterprises to customize workflows, integrate CRMs, and scale AI inference seamlessly across teams.

Algorithmist | Teaching Channel for DSA
