Featured Project
TaskForge
A multi-tenant SaaS workspace with tenant-safe authorization, real-time collaboration, and background processing — designed so organisation boundaries are enforced by architecture, not developer memory.
A Software Engineer who
Builds beyond
the interface…
Because reliable products need more than polished screens.
I'm a Software Engineer.
Currently building secure, scalable digital products at Codenzy,
I work across frontend, backend, cloud, and AI — building multi-tenant SaaS platforms, real-time systems, secure APIs, and concurrency-safe commerce experiences. My focus is dependable architecture, thoughtful user experiences, and software that remains maintainable as products grow.
Recent work, and the decisions behind it.
Featured Project
ShopNest
A commerce system engineered for correctness under concurrency — atomic inventory, idempotent checkout, refresh-token theft detection, and order history that survives catalogue changes.
Featured Project
AI Resume Analyzer
A resume intelligence tool that turns uploaded PDFs into structured candidate profiles, skill and role recommendations, resume scoring, and admin analytics over collected results.
More work, and the technical decisions behind it.

I care about what happens after the feature ships.
I build full-stack applications, backend services, and AI-enabled workflows. I work from the data model and APIs through to the interface, deployment, and fixes that follow a release.
My recent work includes SaaS platforms, secure REST and GraphQL APIs, real-time features, AI assistants, and cloud deployments. I have worked with React, Next.js, Node.js, Python, PostgreSQL, and AWS across different parts of those systems.
I pay attention to what happens outside the happy path: authorization, data consistency, failed requests, and changes that are safe to deploy. I prefer straightforward implementations with clear responsibilities over extra layers that make a system harder to maintain.

Reliable deployments
Good engineering isn't just about making software work. It's about making sure it keeps working when things go wrong. .

Languages I use across product engineering, backend systems, data, automation, and AI.
Responsive interfaces, application state, interaction design, and production-grade web experiences.
Business logic, authentication, APIs, realtime systems, integrations, and service boundaries.
Grounded AI workflows, RAG systems, model integrations, guardrails, and product-facing intelligence.
Relational and document data, schema design, querying, transactions, caching, and persistence.
Infrastructure, containers, CI/CD, testing, observability, and the tooling that keeps systems reliable.
Architecture and engineering principles for maintainable, scalable, secure, and reliable systems.
What I can own end to end.
Product delivery across interfaces, backend systems, AI-enabled workflows, cloud infrastructure, and production reliability.
Full-stack product engineering
Own the path from schema and API contract through responsive interface, state, integration, and production behaviour.
Backend systems & integrations
Design APIs, authentication, queues, realtime flows, service boundaries, and third-party integrations around business invariants.
AI-enabled product workflows
Build grounded AI and RAG-backed product experiences with application data, guardrails, model boundaries, and deterministic rules.
Cloud delivery & reliability
Containerise, deploy, test, and harden systems with CI/CD, cloud infrastructure, failure handling, and production reliability in mind.

Roles where I built, shipped, and improved real products.
Jul 2025 — Present
Lahore, Pakistan · HybridSoftware Engineer
Codenzy
- Built AI/ML-powered product workflows with Python and AWS Bedrock, grounding assistant responses in product data while enforcing business rules, compliance constraints, and controlled response boundaries.
- Developed and maintained backend functionality across Python, Ruby on Rails, and Node.js services, working with PostgreSQL, background processing, APIs, and third-party integrations across production systems.
- Moved monolithic workloads onto Docker-based services running on AWS ECS, with S3 and CloudFront serving static and media assets and Lambda handling asynchronous work outside the request path.
- Built CI/CD pipelines with Jenkins and AWS infrastructure, reducing manual testing effort by 40% and making deployments more repeatable and reliable.
- Hardened APIs with OAuth2, JWT, authorization controls, and rate limiting while integrating Stripe and PayPal payment flows and strengthening reliability through Jest, Cypress, Mocha, and RSpec.
Aug 2024 — Jul 2025
Lahore, Pakistan · HybridAssociate Software Engineer
Codenzy
- Shipped production features for SaaS HR and payroll platforms serving 100+ corporate clients, working across frontend, backend, database, and integration-heavy business workflows.
- Developed backend functionality across Ruby on Rails, Python, and Node.js services, including REST and GraphQL APIs, background processing, data workflows, and third-party integrations.
- Worked on AI/ML-assisted and Python-based product workflows, connecting application data with recommendation, automation, and user-facing functionality.
- Built role-based dashboards and real-time product experiences with React, Redux Toolkit, and WebSockets while improving PostgreSQL schemas and query behaviour behind core workflows.
- Documented APIs with Swagger/OpenAPI, modernised legacy interfaces into maintainable React components, and used Azure Pipelines to support repeatable, zero-downtime deployments.
