Project details

If your app is running but feels fragile, has bugs, slow endpoints, messy deployments, or growing technical debt, this sprint is a structured way to stabilize it without committing to a long, open-ended contract. Ideal for production systems where you want fast progress: fix issues, improve performance, reduce risk and leave the codebase in better shape.

Starter:
 • Triage + fix up to 3 small issues
 • Root-cause notes for each fix
 • One targeted improvement (query optimization, caching, error handling, background job reliability)
Standard:
 • Fix up to 6 issues (bugs, broken flows, API problems, background jobs)
 • Performance pass on the highest-impact bottlenecks (DB queries, caching, N+1, slow endpoints)
 • CI polish: improve or add one GitHub Actions workflow (tests/lint/build)
Advanced:
 • Fix up to 10 issues
 • A focused upgrade or hardening task (pick one):
 • Rails/Ruby upgrade planning + execution for a minor version jump, or
 • Django dependency cleanup + DRF/FastAPI reliability improvements, or
 • AWS production review (ECS/Fargate/EC2 + logs/config) with actionable fixes
 • Practical test coverage added where it reduces future breakage (pytest/RSpec)

FastAPI Engineer for AI Triage Support Tickets Haider ramped up quickly on our FastAPI codebase with minimal guidance and delivered exactly what we needed. He asked the right questions, improved our prompt design for more predictable outputs, and submitted clean PRs with tests and clear hand off notes. He also proactively caught and fixed a security edge case in our authorisation logic before it became a problem which we genuinely appreciated. Highly recommended. Would gladly work with him again.

Lahore, Pakistan - 11:13 pm local time
I’m a full-stack developer with 8+ years of experience building SaaS products and web applications from the ground up — covering architecture, frontend, backend, APIs, and cloud deployment.

I’ve worked directly with founders and product teams who needed a developer that thinks about the product, delivers reliably, and doesn’t require constant oversight.

What I typically work on:

Scalable, multi-tenant SaaS platforms built for long-term growth
End-to-end web applications using React, Next.js, Node.js, and PostgreSQL/MongoDB
REST and GraphQL APIs with reliable third-party integrations
Authentication and authorization using JWT, OAuth2, SSO, and RBAC
AWS deployments with CI/CD pipelines, Docker, and containerized setups
Frontend interfaces that are fast, responsive, and maintainable
Backend systems designed for scalability and performance
Database architecture using PostgreSQL, MongoDB, MySQL, and Redis

How I work:

Clear execution plan from day one with milestones and risk identification
Deep requirement understanding before writing any code
Agile development with transparent, consistent communication
Clean, documented code built for long-term maintainability
Post-launch support and scalability planning

I work best with clients who:

Are past the idea stage and ready to build
Value clean architecture over shortcuts
Want a developer who communicates clearly and asks the right questions
Are building SaaS products, web platforms, or internal tools that need to scale

Technical stack:

Frontend: React.js, Next.js, JavaScript (ES6+), TypeScript, TailwindCSS, HTML5, CSS3
Backend: Node.js, Express.js, Python, Django, FastAPI, REST APIs, GraphQL
Databases: PostgreSQL, MongoDB, MySQL, Redis
Cloud & DevOps: AWS (EC2, S3, RDS, Lambda), Docker, Kubernetes, CI/CD, GitHub Actions
Auth & Security: JWT, OAuth2, SSO, RBAC, WebSockets, API security best practices
