Software Engineer

I build backend systems in Python: FastAPI services and SQL data models, plus LLMs and agentic AI workflows on top of them with LangChain.

I'm a Software Engineer based in Lahore, Pakistan, specializing in backend development and AI integration. I spend most of my time in Python: building APIs with FastAPI, designing the SQL models behind them, and integrating LLMs and agentic AI workflows with LangChain.

I've also worked on payments: a Finix integration for card tokenization and webhook reconciliation, plus Oracle FLEXCUBE's core banking modules earlier in my career.

TruAris

private repo

TruAris is a fully autonomous, multilingual outbound sales and lead engagement platform. It handles the complete lead lifecycle: cold import, qualification, follow-up, escalation to human reps, and CRM pipeline management. I started this project from scratch and built its core backend, and I'm still actively developing it while guiding the frontend implementation. I own the backend end to end: the business logic, organization-scoped tenancy with Postgres row-level security enforced through a non-superuser app role, Celery workers running prospecting, channel identification, and batch scoring, the LangChain-based LLM layer switching between OpenAI and Anthropic, and the AWS deployment and GitHub Actions CI/CD pipeline behind it.

private repo

Backend for an enterprise change-management platform. Tracks stakeholders, initiatives, and department-level readiness and impact, models cultural resistance and sentiment across an organization, and scores training adoption. AI-assisted endpoints generate scenario recommendations, and the reporting layer exports findings to PDF, Excel, and PowerPoint.

Osala

private repo

Backend for a beauty and business management platform used through a mobile app. Handles bookings, catalog, and scheduling, plus a full Finix payment integration: card tokenization, subscriptions, webhook-driven reconciliation, and dispute handling. Backed by Postgres through Supabase with Alembic-managed migrations. I designed and built the Classes module (regular classes and workshops) and the audit logging module, and fixed timezone handling issues across the project.
