Ali Haider Nadeem

Senior software engineer. I build the dense, real-time interfaces that operations teams live in, and I own them from a loosely defined problem to a shipped feature. Six years in, three of them fully asynchronous across a twelve-hour gap with teams in California and the UAE. Today I work on Backstock at XFinLabs.

Open to senior full-stack roles, frontend-strong. Remote, UTC+5.

Backstock

Every location. One inventory.

Backstock: Every location. One inventory.

Inventory management for sneaker and streetwear resellers: a Next.js web app and a Flutter mobile app on top of .NET services and Salesforce. Replaces the spreadsheet with a live dashboard, bulk listing, condition grading, multi-location stock, CSV import, and a single inbox for offers with profit already calculated.

I own features end to end: the Next.js client, the .NET services behind it, and the Salesforce sync that keeps inventory current without anyone re-keying it. The shared component library I built standardized the B2B screens and cut delivery time by a quarter.

The mobile app is Flutter, built for the reseller who is grading a pair in a warehouse aisle rather than sitting at a desk. Everything ships asynchronously with a team twelve hours away: written specs, PR-driven review, and progress notes instead of meetings.

Rocdel

Six agents, one pipeline, human-approved.

Rocdel: Six agents, one pipeline, human-approved.

An agentic AI revenue platform. Six agents enrich, score, draft, call, meet, and forecast, grounded in RAG over the team's own revenue history. Every claim carries a record citation and nothing reaches a prospect without a human approving it. Tools are reached through MCP servers with scoped credentials; an eval harness gates every prompt or model change before deploy.

The architecture is five layers with one rule between them: a human approval gate sits between every agent output and any external send. Agents reach tools through MCP servers that hold scoped credentials, so an outreach agent can send as a rep but never read the inbox.

Postgres with pgvector holds the revenue corpus, Redis Streams runs the task queue, and OpenTelemetry traces every step from retrieval to tool call. Prompt and model changes replay the eval harness before they ship; a regression on any metric blocks the deploy.

Nightbell

The phone rings at 2 AM. It gets answered.

Nightbell: The phone rings at 2 AM. It gets answered.

A 24/7 AI voice agent for plumbing and HVAC companies. Answers every call in under two seconds, triages real emergencies from a versioned rule matrix, pages the on-call tech while coaching the caller, and books everything else straight into the schedule. Gas and CO calls hit a hard-coded safety route that a prompt cannot reach.

Twilio handles the number and SIP trunk. Vapi runs streaming speech to text with barge-in, so a caller can always interrupt. A Python service classifies each call against a triage matrix that is versioned in git and loaded at call start.

Gas and carbon monoxide calls take a separate hard-coded route: safety script, evacuate, owner notified, booking path unreachable by design. Every tool call lands in an append-only event log, and a weekly transcript sample scores triage accuracy before any matrix change deploys.

Code

  • Switchyard

    Couples and uncouples containers on Railway.

    A small control panel that starts and stops containers on Railway through Railway's public GraphQL API, and runs on Railway itself. Each service is a section of track with a signal lamp for deployment status. The app lists itself, marked protected, because it is deployed into the project it manages.

    Solo build. Hono, React, TypeScript, Railway GraphQL API, GitHub Actions. Public repo, CI green, password-protected demo.

  • Threshold

    Interrupts autopilot in the first seconds after boot.

    A local-only Windows app that opens a twenty-second fullscreen prompt at boot, wake, or unlock: what you are here for, whether you will start it before opening anything else, and how long you are committing. It can then block distracting sites system-wide across every browser and profile, and keeps a small local record. A Flutter companion app is in progress.

    Solo build. Rust, Tauri, React, Vite, Flutter. Private repo, in active development.

  • The Drop

    Orange County's #1 showroom, online.

    Shopify storefront for an appointment-based luxury streetwear and vintage showroom in Tustin, California. Custom Dawn 2.0 theme work: appointment booking, cart, menu search, product and collection pages, all configurable from the theme editor with vanilla JavaScript and no added dependencies.

    Theme developer, client work. Shopify, Liquid, Dawn 2.0, Vanilla JS. Live.
