I build backend APIs in Python — clean, working endpoints your app or frontend can rely on. Most of my work is REST APIs with Django and FastAPI, and I'm comfortable taking a feature from the idea to a working endpoint. What I can help with: REST APIs — building and extending APIs with Django REST Framework or FastAPI: clear endpoints, validation, error handling, and documentation. Database work — PostgreSQL and MySQL: designing tables, writing queries, indexing, and migrations. Practical data work that fits what you're building. Integrations — connecting third-party APIs and services into your backend: payments, external APIs, webhooks. Background tasks — Celery and Redis for jobs that run in the background, like emails, exports, or scheduled work. Fixing and extending — picking up an existing Django or FastAPI project, adding features, or cleaning up messy code without breaking what already works. I'm a good fit for: - New APIs, or adding endpoints to an existing backend - Smaller or well-defined backend tasks you want done properly - Extending or fixing a Django/FastAPI project - Clean code you or your team can build on later I keep things simple and do the task properly. Tell me what you need and I'll help you get it working. Tech: Python, Django, FastAPI, PostgreSQL, MySQL, Redis, Celery, Docker

I used to be the person on the support team fielding the same integration question five times a day - because the docs never explained it properly. That's what pulled me into technical documentation engineering. Not theory. The actual gap between what a product does and what a developer or non-technical end-user can figure out from the docs alone. Since then, I have spent my time cleaning up that gap for SaaS companies. I write and structure API documentation that developers can actually follow without pinging support - OpenAPI/Swagger specs, endpoint references, authentication guides, quickstarts, and the kind of "Getting Started" pages that stop a new user from bouncing in the first five minutes. A good chunk of my recent work has also been in n8n - documenting custom nodes, workflow logic, and automation setups so that teams (and their clients) understand exactly what's running under the hood and why. I like this kind of work because it sits right at the intersection of technical accuracy and plain-English clarity - you need both, or the doc is useless. {What I bring to your project}: - API documentation (OpenAPI/Swagger, REST, Postman collections) - SaaS product docs, help centers, and onboarding guides - n8n workflow and node documentation - Rewriting/auditing existing docs that are outdated, inconsistent, or just confusing If your product works but your documentation is quietly costing you support tickets, churn, or dev time - that's exactly the kind of mess I like sorting out. Send me a message and tell me what you're working with. ------------------------------------------------------------------- {My Background and Skillset} With a strong background in software engineering and web development, I understand the systems behind the documentation. This allows me to work directly with APIs, codebases, product teams and technical stakeholders to create accurate, well-structured documentation that stays useful as products evolve. 🔹 User Guides | How-to Guides I create clear, task-focused documentation that helps users understand your product, complete workflows efficiently, and reduce dependency on support teams. ✅ User guides ✅ How-to guides ✅ Step-by-step tutorials ✅ Product onboarding guides ✅ Feature walkthroughs ✅ Knowledge base articles ✅ FAQs and troubleshooting guides ✅ Internal process documentation ✅ User manuals ✅ Visual workflows and screenshots 🔹 API Documentation (OpenAPI / Swagger Expert) I create complete, production-ready API documentation that includes: ✅ Clear endpoint descriptions ✅ Request body parameters ✅ Query parameters & path parameters ✅ Authentication flows (JWT, OAuth, API Keys) ✅ Response structures with status codes ✅ Error codes with detailed schemas ✅ Properly defined data models ✅ Example requests & responses ✅ Postman collections ✅ SDK usage examples I work extensively with: Markdown • YAML • JSON • OpenAPI • Swagger • Redocly • Postman • GitHub ▪︎ ReadMe • Google Docs ▪︎ Zendesk • Docusaurus Your APIs will not only function well - they will be understood instantly. 🔹 Developer & Technical Documentation I create: ✅ Developer Guides ✅ API References ✅ SDK Documentation ✅ Integration Guides ✅ Database Documentation (SQL & NoSQL) ✅ System Architecture Documentation ✅ Technical Blogs & Articles ✅ Internal Engineering Documentation ✅ System Operating Procedures (SOPs) ✅ User Manuals ✅ How-To Guides ✅ Step-by-Step Tutorials Whether your audience is developers, internal teams or non-technical users - I adapt tone, depth and structure accordingly. 🔹 Developer Portals & Documentation Platforms I build structured, branded documentation portals using: ✅ Redocly ✅ ReadMe ✅ GitBook ✅ Docusaurus ✅ Mintlify ✅ Stoplight ✅ Confluence ✅ GitHub I ensure your documentation is searchable, scalable, version-controlled, and beautifully structured. 🔹 Technical & Engineering Strength My technical capabilities allow me to go beyond surface-level writing: ✅ Testing and validating APIs with Postman ✅ Running and testing SDKs ✅ Code commenting and codebase documentation ✅ JavaScript & TypeScript documentation ✅ Python code refactoring & documentation ✅ REST API workflows ✅ JSON, YAML, HTML, CSS ✅ Database structure documentation (SQL | NoSQL) Because I understand the code, I document it accurately. ----------------------------------------------------------------------------------- ##TechnicalDocumentationEngineering #TechnicalWriting #TechnicalDocumentation #UserDocumentation #UserGuides #APIDocumentation #OpenAPI #Swagger #SOPWriting #KnowledgeBase #DeveloperDocumentation #InstructionManual #ProcessDocumentation #SoftwareDocumentation #Markdown #GitBook #n8n #n8nAutomation
