  1. Reading someone else's documentation well is its own skill, separate from writing the code. The single most important sentence in the whole integration, that access is granted from the signed webhook and never the redirect, was buried a click deeper than the main guide. That is the story, not the Stripe plumbing itself.

  2. Built the same way as everything it lists: a design doc, a dependency-ordered plan, one commit per verified task. The site is not a writeup about the pivot, it is the pivot, running in public.

  3. The real lesson was not any single bug. An AI coding agent will happily produce code that runs, looks fine, and is quietly wrong. Planning first and checking both behavior and structure is what caught a login timing leak, a broken migration, and a wrong uniqueness rule.

  4. The CRUD core is done and clean-slate verified, the floor the rest stands on. Auth comes next, then a semantic graph, then an agent layer on top. Nine milestones, each with its own design doc and learning write-up.

  5. Public from commit one changes how you build. Every choice gets a written reason before the code, because the reasoning is part of the repo. The discipline is the point, not a side effect of it.

Projects

  • Problem

    Notes, tasks, and links live in disconnected tools that never show how anything interlinks, and none of them actually know you.

    Approach

    Two services over an HTTP contract: a NestJS API for notes, tasks, auth, and kanban, and a FastAPI AI layer, orchestrated with Docker Compose. Strict layering: thin routers, service logic, repository DB access. Nine stacked milestones from plain CRUD to pgvector semantic search, GraphRAG over Neo4j, and an MCP-exposed agent.

    Outcome

    In active development, documented milestone by milestone with design docs, plans, and learning write-ups in the repo.

  • Problem

    Public-company research is fragmented across EDGAR, market data sites, and filing types, and generic AI chat answers without citing filings.

    Approach

    One workspace per ticker: filings, fundamentals, charts, governance, and TickerChat, a Claude-powered assistant grounded in official SEC documents, with PDF export. Next.js frontend on Vercel, FastAPI ingestion service on Render.

    Outcome

    Placed 2nd at the hackathon. Live demo online.

  • Problem

    Raw city-scale transit data is useless without curation, and dashboards alone don't answer ad-hoc questions.

    Approach

    PySpark pipeline over AWS S3 producing curated datasets; XGBoost, Random Forest, and LSTM models for fare and demand forecasting; models served via a FastAPI MCP server and a conversational agent built with Strands Agents on AWS Bedrock.

    Outcome

    End-to-end: raw data to models to a chat interface for real-time mobility insights.

  • Problem

    Repetitive multi-service workflows burn hours and break silently when APIs rate-limit or duplicate work.

    Approach

    Node.js pipeline using the Claude API for evaluation and generation, Google Sheets and Drive for state, Apollo for enrichment. Built around production concerns: per-task model routing, safe re-runs that skip completed work, rate limiting, deduplication, OAuth per provider, and a human approval gate at every stage.

    Outcome

    Powers a real job search end to end, but the design generalizes to any service-orchestration workflow.

Publications

    This research introduces a task scheduling algorithm inspired by Artificial Neural Networks (ANN), designed to deliver superior power efficiency and scalability compared to existing methodologies. By leveraging the predictive capabilities of ANN, the algorithm achieves constant-time predictions, even as task loads scale significantly.

    Experimental evaluations using real log files demonstrate performance across metrics such as average start time, finish time, execution time, resource utilization, task failure rates, and power consumption. The model's robustness is proven in both underloaded and overloaded data center conditions, ensuring efficient task scheduling while maintaining system stability under dynamic workloads.

    This review examines the critical challenges facing fog and edge computing architectures, which play a pivotal role in managing the explosion of sensor-driven data. The study highlights pressing issues such as security vulnerabilities, network latency, and inefficient resource utilization, providing an in-depth analysis of existing solutions.

    The paper explores advanced approaches, including nature-inspired algorithms and metaheuristic optimization techniques, as promising solutions to enhance the performance of fog and cloud computing systems, serving as a guide for researchers and practitioners in next-generation computing environments.

    This paper investigates the application of the Harmony Search Algorithm (HS) for task scheduling in cloud environments, offering a comparative analysis against Genetic Algorithms (GA) and Moth Search Algorithms (MSA). Simulations conducted using CloudSim and MetaheuristicOpt packages reveal HS as a highly efficient and cost-effective solution for dynamic task scheduling.

    The study evaluates performance across key metrics, demonstrating HS's superiority in optimizing execution time, resource allocation, and operational costs, setting a foundation for further exploration in metaheuristic-based task scheduling methodologies.

About

Pratyush Agarwal

I spent three years working with data across Kohler, Apna, and Google, building pipelines, automation, and systems that teams relied on every day. Somewhere along the way I realized the parts I loved most were the software parts: designing APIs, shipping products, watching people use what I built. So I'm going all in on software engineering.

I don't have years of a traditional SWE / SDE / Product Engineer title behind me, but I have production experience, I learn fast, and I'm building the proof in the open: every project public, every milestone logged, every lesson written up. If you want to see how I work, it's all here.
