Project details

You will get a production-ready Python backend built by an experienced Python developer focused on backend development for real web applications. I design clean architecture and system boundaries, then build and integrate secure API / APIs using REST and RESTful patterns (Django/FastAPI/Flask). Your project includes database schema and SQL work with PostgreSQL (or MySQL/SQLite) using SQLAlchemy where appropriate, plus performance optimize (queries, indexing, caching), security (OAuth/OAuth2/JWT authentication), and reliable integration via webhooks. I can add Redis caching and queue-based background jobs, and deliver smooth deployment with Docker on Linux server environments, with CI/CD, DevOps, and cloud deployment on AWS or Azure. The goal is simple: scalable, secure, high-performance backend systems that scale.

Python Developer for Telegram Bot MVP (AI Audio/NLP + Mobile Money API) Osama is an exceptional full-stack engineer. He delivered solid, production-grade architecture, communicated with absolute clarity, and provided sharp technical insights before a single line of code was written. He is highly reliable, security-focused, and transparent. I highly recommend him for any serious SaaS or backend integration project, and I look forward to working with him on future phases.

Python developer helping teams take ownership of backend systems, fix unstable codebases, and scale real-world applications, building APIs, SaaS platforms, and automation workflows using Django, FastAPI, and modern Python practices focused on production environments.


I work with teams to build reliable, scalable products out of systems that are partially built, unstable, or not yet ready for production.

Many teams I work with struggle with bug-heavy code, slow APIs, or integrations that break under real usage, I focus on fixing the root issues, not just patching symptoms.

From stabilizing MVPs and debugging complex workflows to scaling backend services and AI pipelines, I help teams ship systems that actually work in production.

Whether it’s handling high-load traffic, fixing failing integrations, or improving performance, I work like a long-term team member focused on delivery, not just tasks.



𝐑𝐞𝐜𝐞𝐧𝐭 𝐰𝐨𝐫𝐤 𝐚𝐜𝐫𝐨𝐬𝐬 𝐢𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬:

✓ 𝐇𝐞𝐚𝐥𝐭𝐡𝐜𝐚𝐫𝐞 & 𝐁𝐢𝐨𝐭𝐞𝐜𝐡
Built secure case management and research platforms with real-time data processing, role-based access, and cloud infrastructure, improving decision-making and reducing manual workflows.

✓ 𝐅𝐢𝐧𝐭𝐞𝐜𝐡 & 𝐓𝐫𝐚𝐧𝐬𝐚𝐜𝐭𝐢𝐨𝐧 𝐒𝐲𝐬𝐭𝐞𝐦𝐬
Developed backend systems handling real-time bookings, secure payments (Visa, Apple Pay, etc.), and high-concurrency user traffic with reliable API architecture.

✓ 𝐀𝐈 𝐒𝐚𝐚𝐒 & 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧
Built multi-tenant AI platforms with LLM integrations, agent-based workflows, and automation pipelines handling high-volume data processing and decision-making.

✓ 𝐄𝐧𝐭𝐞𝐫𝐩𝐫𝐢𝐬𝐞 𝐒𝐚𝐚𝐒 & 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦𝐬
Designed microservices-based systems with async APIs, real-time notifications, and scalable architecture supporting thousands of users.

✓ 𝐄𝐝𝐮𝐜𝐚𝐭𝐢𝐨𝐧 & 𝐂𝐨𝐥𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐢𝐨𝐧
Developed large-scale learning platforms and AI-powered support systems with real-time interaction and personalized user experiences.



Clients commonly hire me for:

✓ Building backend systems and REST APIs with Python using Django, FastAPI, and Flask, with strong focus on clean architecture, scalability, authentication (JWT/OAuth2), and production-ready design


✓ Developing full-stack web apps using Django/FastAPI with React or Next.js, ensuring smooth frontend-backend integration and user experience


✓ Creating and maintaining PostgreSQL/MySQL/MongoDB database-backed platforms with efficient schema design and optimized queries


✓ Integrating third-party APIs such as OpenAI, Anthropic/Claude, Stripe, Twilio, Telegram, payment gateways, property APIs, ad APIs, and webhook-based services


✓ Building AI-powered product features including LLM workflows, prompt-based automation, chatbots, assistants, document Q&A, recommendation systems, lead scoring, OCR/data extraction, and structured AI outputs using OpenAI and LangChain


✓ Designing automation systems and data workflows including web scraping, and data processing using BeautifulSoup, Scrapy, Selenium, Playwright, and HTTPX for real-time and scheduled systems.


✓ Improving existing codebases through bug fixing, code review, stabilization, refactoring, and production hardening without unnecessary rewrites


✓ Setting up Docker, CI/CD pipelines (GitHub Actions), cloud deployment, DevOps workflows, and AWS/Azure infrastructure for scalable systems


✓ Optimizing applications for performance, scalability, reliability, security, and maintainability in production environments



I’m a strong fit for projects that require:

✓ Clean, scalable architecture
✓ Authentication flows such as JWT/OAuth2
✓ Strong database design and data handling
✓ Production-ready APIs and backend systems
✓ API integrations and webhook-driven systems
✓ Secure handling of user data, file uploads, and payment flows
✓ Async processing, queues, retries, caching, Redis, Celery, and worker pipelines
✓ Thoughtful debugging and improving existing systems without over-engineering



If you work with me, here's what I focus on:

✔ Ownership mindset
✔ Clean, scalable solutions
✔ Production-ready delivery
✔ Stability first, not quick fixes
✔ Clear communication & predictable progress

Revisions may occur after the delivery date.

Requirements + system design

Confirm scope, APIs, authentication, integrations, database schema, and success criteria. Produce a clean backend architecture/system design plan (REST/RESTful, webhooks, security, scalability, performance).

Build backend APIs + database layer

Implement Python backend development with Django/FastAPI/Flask, SQLAlchemy models, PostgreSQL/MySQL/SQLite schema, REST/RESTful endpoints, validation, error handling, and integration/webhooks.

Review the work, release payment, and leave feedback to Osama.
