Get In TouchAbout Me
I'm a backend engineer with deep expertise in system architecture, database optimization, and REST API development. I specialize in Python/Django, microservices, and multi-tenant SaaS platforms, automating processes and building scalable solutions that are both fun and impactful.
As a Software Engineering (DIPHE) graduate from the University of Leicester, I've since built and shipped multiple production systems, including TopsoftDigitals Connect — a real-time Django project management platform with WebSockets, Celery, and S3 pipelines that's currently running live in production — replacing expensive third-party tooling with custom infrastructure. Whether it's coding, developing games, or combining technologies in innovative ways, I'm always creating projects that blend creativity with problem-solving.

Featured Projects
TopsoftDigitals Connect
A real-time project management platform for digital agencies that ties together workspaces → clients → teams → tasks → posts & comments. Built on Django 6.1 + PostgreSQL with PgBouncer connection pooling, Celery (gevent) + Redis power async pipelines for Slack DMs, WebPush (VAPID) notifications, S3 file cleanup, and an IMAP email-alert scanner. A Redis-backed Channels layer streams live WebSocket notifications and activity-feed badges, while HTMX + Bootstrap 5 deliver a snappy SPA-less UI. Features an approval-orchestrated completion workflow (pending → awaiting approval → completed), 8-type role-based permissions, a token-based client portal with two-way comments, DM live chat, SLA-clocked support tickets, an installable PWA, direct browser-to-S3 presigned uploads, a Ctrl+K command palette with Redis-cached JSON search, and a superuser-only sales/payments ledger. Containerised and deployed on Railway behind WhiteNoise + Brotli with versioned Redis fragment caching.
IBM SkillsBuild Simulation Platform
Led a cross-functional team of five as Scrum Master to a 2nd-place finish in the IBM SkillsBuild national competition. Architected a full-stack simulation platform serving 500+ concurrent users with secure RESTful APIs, real-time feedback loops, role-based dashboards, and persistent session state. Built on Java 17 + Spring Boot with Hibernate ORM against a relational MySQL backend, the frontend combines Bootstrap 5 responsive layouts with jQuery-driven dynamic interactions, delivering a polished UX that the judges ranked among the top three platforms nationwide.
Blink Digitally Publishing Dashboard
Designed and delivered a production-grade Publishing Dashboard (~6,000 LOC) that saved an entire editorial team 12+ hours per week on manual reporting. Built on Streamlit with Pandas for high-volume data transformation, NumPy for statistical aggregations, and Matplotlib/Seaborn for automated chart generation, rendering weekly performance summaries, ad-revenue trends, and content velocity graphs with zero manual intervention. Integrated Google Sheets API for live publisher data ingestion and a custom Slack bot for automated review reminders and status notifications triggered by GitHub Actions.
Blink Digitally Ticket Management App
End-to-end ticket management system processing 200+ active tickets across distributed teams. Streamlit frontend backed by Pandas for real-time dataframes, NumPy for SLA deadline calculations, and Matplotlib for burndown-chart visualisations of team velocity and aging tickets. Notion API serves as the primary data store with relational page links, while GitHub Actions schedules daily cron-driven Slack/email reminders (Mon-Fri, 8:00 PM PKT) that ping ticket assignees and creators with personalised digests, reducing overdue items by 40% in the first month.
Cafe 1947 Website & Booking System
Full-featured cafe website with a real-time booking engine that replaced a manual phone-and-paper reservation system. Streamlit backend handles booking validation, time-slot availability checks, and automated confirmation flows, all synced with a Notion database acting as the live reservations ledger. Frontend built with responsive HTML/CSS and vanilla JavaScript for interactive menus and gallery components. Pandas processes booking analytics (peak hours, popular items, table-turn rates) for weekly operational reporting.
FAQs
What technologies do I specialize in?
I specialize in Python, Django, PostgreSQL (with PgBouncer connection pooling), Celery, Redis, FastAPI, Java / Spring Boot, Docker, and multi-tenant system architecture. I build production-grade backend systems and REST APIs that replace entire enterprise tool stacks at a fraction of the cost.
What is my most notable project?
My flagship project is TopsoftDigitals Connect, a real-time project management platform built on Django 6.1 + PostgreSQL (with PgBouncer), Channels/WebSockets, Celery, and Redis. It serves active client organizations via workspaces, teams, tasks, and an approval-orchestrated completion workflow, with a client portal, live chat, Slack DMs, WebPush (VAPID), S3 uploads, and a Ctrl+K command palette — replacing an entire enterprise tool stack (Basecamp, Asana, Trello, Slack bots, spreadsheets) and saving $15,600/year at roughly 94% lower monthly infrastructure cost.
Where am I based?
I'm based in Karachi, Pakistan, and work as a Backend Developer at Top Soft Digitals. I'm open to remote opportunities worldwide.
What measurable impact has my work achieved?
Across 4 production systems currently running live, my work has: saved $15,600/year in tooling costs (94% cost reduction), tracked and protected $92,900 in revenue, replaced 5 separate tools with one custom engine, and maintained a 100% deadline record with zero missed deliveries. I also enabled 4 new service lines that previously weren't feasible due to expensive SaaS tooling.
