flashclass
flashclass is an AI-powered adaptive learning platform that teaches programming through high-volume code exposure and pattern recognition. Rather than a fixed curriculum, it generates every session around the individual learner's personality and preferred mode—audio, video, or text.
I built the AI layer on AWS Bedrock AgentCore: the session-generation agents, their tools, and the memory model that carries learner context across sessions. Bedrock foundation models handle generating, rewriting, and paraphrasing code snippets and questions. Embedded "gnosis" assessment questions continuously refine each user's personality profile, and the platform adapts its cognitive load and pacing accordingly.
I also designed and developed the Next.js front end, the PostgreSQL schema for sessions, profiles, and metrics, and the analytics pipeline that tracks recognition, engagement, and progression—which feeds back into profile updates.
Stack: Next.js, Tailwind CSS, AWS Bedrock AgentCore, Amazon Bedrock, Neon Postgres, Drizzle ORM, Clerk, Vercel.

MiAid
A full-stack platform that helps users locate, collect, and enrich data on hospitals and pharmacies globally. It aggregates listings via the Google Places API, uses custom Scrapy web scrapers for detailed content extraction, and leverages OpenAI's LLMs to fill in missing information such as hospital specialties and operating hours. I built the Django back end, the Scrapy scraping pipelines, and Celery-based background processing, along with an admin interface for data validation and approval and real-time JCI-accreditation verification. The UI is a responsive, dark-themed Bootstrap 5 front end.
TrendVesting
https://trendvesting.aiAn AI-powered investment-intelligence platform that helps retail traders identify and act on market signals. It combines real-time trend tracking, a multi-agent "Room of Experts" LLM consensus engine that scores signals via Temporal workflows, broker integration for trade execution, and a social layer. I helped build it as a multi-service system: a Go backend (Chi, GORM), a Python/FastAPI AI microservice using OpenRouter LLMs, a Next.js web app, and a React Native mobile app, all deployed on DigitalOcean Kubernetes with RS256 JWT auth shared across services and SnapTrade for brokerage OAuth and live trade execution.
AI Submittal Report Generator
An AI-enabled web application that automates the generation of engineering submittal reports for a construction-industry client. It parses technical documents, extracts key engineering parameters, recommends optimal concrete slab systems, validates compliance with standards such as AASHTO, ACI, and ASTM, performs cost analysis, and generates versioned reports with MS Word export. I contributed to the Django and React application, the OpenAI-powered document parsing and recommendation logic, and the AWS-based DevOps setup, along with user roles, project management, and in-line collaborative commenting.

upgrade-advisor
https://github.com/umairwaheed/upgrade-advisorAn Amazon Bedrock AgentCore agent that answers: Should we take this dependency upgrade, and what will it cost us?
Point it at a package and the version you're pinned to. It pulls the live release ladder from PyPI or npm, reads the maintainers' release notes from GitHub in a cloud browser, scores the upgrade risk based on reproducible code, and checks what your team has decided about similar upgrades before. You get back a typed verdict — ADOPT, ADOPT_WITH_CARE, STAGE, or DEFER — with a point-by-point score breakdown, the concrete breaking changes, and an ordered list of what an engineer actually has to do to land it.

Pulse
Pulse is an internal tool I developed for a software services company. It integrates with the company's Odoo ERP, Zulip chat application, and Microsoft tenant. Login is handled through Microsoft SSO, and it uses the Microsoft Graph API to retrieve user information and roles. Employees give their standup updates on Zulip, and Pulse marks attendance and collects all the updates. It also integrates with GitHub to track development activity and with the CRM to track sales activity. Role-based access control (RBAC) ensures that users have access only to the data they are authorized to see.
