Product Systems · Data Science · Creative Front-End Prototypes

Hi, I'm Saisha Ketkar.

Hi, I'm Saisha Ketkar, a Data Science and Economics student at Northeastern University. My work spans AI-inspired product prototypes, data systems, dashboards, automation workflows, and interactive front-end projects. I like building tools that are practical enough to use, clear enough to understand, and polished enough to feel intentional.

About

Designer-builder with a data systems foundation.

I work across front-end prototyping, UX writing, workflow design, analytics, and backend/data systems. My experience includes ServiceNow workflow tools, reporting dashboards, Notion and Slack automations, generative AI documentation workflows, and scalable storage projects using Python, JavaScript, React, SQL, MongoDB, MySQL, Redis, ServiceNow, Tableau-style dashboards, Excel Power Query, Notion, and Slack. Across my projects, I care about making information more usable and experiences more approachable.

01

Creative prototypes

Interactive web projects that explore journaling, focus, self-expression, and playful everyday tools.

02

Data and systems

Database, analytics, and storage projects that show how I structure information and evaluate technical tradeoffs.

03

Workflow design

Automation, documentation, and operational tools built to reduce friction and make teams move faster.

How I work

Frame the problem → map the flow → build the prototype → test the details → document the decisions.

I like projects where the interface and the system support each other: the product should feel intuitive on the surface, while the underlying structure handles data, state, content, and future expansion thoughtfully.

Projects

Journal Scrapbook Buddy

Journaling UX · AI-Inspired Reflection · JavaScript

A playful journaling prototype where users write what they are carrying, select multiple colors and a vibe, generate a personalized scrapbook page, save scraps to a growing local book, and export the current page as a PDF. The project explores how reflection tools can feel creative, gentle, and personal instead of blank or clinical.

Live demo GitHub repo Design process A/B test

What I built

  • Designed a repeatable journaling system with emotional input, multi-color customization, generated reflection, save-to-book, and PDF export.
  • Used browser localStorage to preserve saved scraps in a growing personal book.
  • Created a soft visual language that makes reflection feel approachable while keeping the user in control.

Process

  • Documented product framing, low-fidelity wireframes, interaction states, content decisions, prompt strategy, and accessibility notes.
  • Defined boundaries around generated reflection so outputs stay creative and reviewable.
  • Implemented a lightweight A/B test comparing creation-button copy and tracking local visit-to-create and create-to-save behavior.

Focus Bakery

Gamified Productivity · Interaction Design · JavaScript

A bakery-themed focus companion where each completed focus round unlocks an ingredient. After five rounds, the user bakes a cute treat and adds it to a growing shop collection. The prototype reframes productivity as a warm progression system instead of a pressure-based task tracker.

Live demo GitHub repo Design process

What I built

  • Designed a clear loop: focus round → ingredient → recipe → baked item → shop collection.
  • Created a scalable recipe system with multiple bakery items, progress states, collection cards, and local persistence.
  • Added warm reflection notes so users can connect completed work to a small moment of progress.

Process

  • Documented wireframes, interaction flow, content decisions, accessibility considerations, and future expansion paths.
  • Used playful interaction patterns to make productivity feel motivating without relying on guilt or pressure.
  • Designed the system so new recipes, seasonal menus, shop decorations, and recap cards can be added later.

Twitter Storage & Retrieval System

Python · MySQL · Redis · SQL

A Twitter-style backend system built to support tweet posting and home timeline retrieval at scale. I designed relational schemas for users, tweets, and follower relationships, implemented API-style functions like postTweet and getHomeTimeline, and benchmarked relational versus in-memory storage tradeoffs.

Technical focus

  • Benchmarked 1M tweet insertions and 50K timeline requests.
  • Improved insertion throughput from approximately 3,906 to 5,574 calls per second using Redis.
  • Evaluated read/write performance tradeoffs for high-volume social media workloads.

MongoDB News Classification Data Pipeline

Python · MongoDB · JSON · Aggregation Pipelines

A document-store data pipeline for transforming raw sarcasm headline data into structured MongoDB-ready documents. I cleaned malformed URLs, extracted source domains, created nested headline records, and wrote aggregation pipelines to analyze sarcasm rates and keyword trends.

Data modeling

  • Designed a flexible document schema with nested records and derived text features.
  • Used mongoimport, indexing, and aggregation stages including $unwind, $group, and $project.
  • Compared modeling tradeoffs for nested retrieval, analytics queries, and scalable ingestion.

Aircraft Incident Data Quality & Analytics Database

MySQL · R · SQL · ETL

A normalized analytics database for aircraft incident data. I designed a 3NF MySQL schema, built an ETL pipeline in R, deployed a cloud-hosted MySQL database with secure SSL, and produced SQL-driven analytics across monthly, airline, and yearly trends.

Analytics system

  • Applied statistical analysis and functional dependencies to structure the schema.
  • Validated data integrity with quality-control checks before downstream analytics.
  • Created modular SQL query patterns for reusable analytics access.

Notion + Slack Operations Automation

Notion · Slack · Workflow Design · Operations

An operations and finance workflow system built for TAMID at Northeastern to coordinate reimbursements, budgeting, event planning, and member processes across a 100+ member organization. The system connected Notion workflows with Slack notifications to reduce manual follow-up and improve operational visibility.

Workflow impact

  • Designed a centralized operations system for finance requests, approvals, and leadership visibility.
  • Integrated Slack notifications to automate reimbursement updates and reduce manual coordination.
  • Built the system around real organizational needs, recurring tasks, and cross-functional communication.
