Hire the Best Python Script Programmers
in Ethiopia

"I'm an experienced backend & automation developer who builds fast, scalable, zero-maintenance systems.What I actually build and ship every week: Go (Golang) – high-performance APIs, microservices, CLI tools, concurrent workers Node.js – Express/Fastify/NestJS, real-time apps, webhooks, serverless functions Python & Django – full-featured backends, admin panels, REST/GraphQL APIs Databases – PostgreSQL, MySQL, MongoDB, DynamoDB, Redis Web scraping & data extraction – Playwright, Puppeteer, Scrapy, Selenium, rotating proxies, anti-bot bypass — clean and reliable Microservices architecture – Docker, Docker Compose, event-driven, AWS Lambda + API Gateway, Kubernetes-ready Automation with n8n – self-hosted or cloud, custom nodes, bulletproof workflows between all your apps Smart bots & agents – GPT-4o, Claude 3.5, Gemini, Grok, Llama 3 via API → chatbots, auto-responders, content generators, decision agents Infra that never breaks – Linux, Bash, systemd, PM2, Caddy/Nginx, Terraform when needed Bottom line: I build rock-solid backends and microservices (Go/Node/Django), store data wherever it makes sense (including DynamoDB), scrape anything legally and reliably, automate everything with n8n, and supercharge it all with the best AI APIs.

I build AI systems that don’t just work, they perform, scale, and deliver actionable insights. I specialize in architecting production-ready large language models with ultra-low latency and precision-driven outputs. From retrieval pipelines to inference optimization, I turn complex AI into reliable, real-world solutions. I design advanced Retrieval-Augmented Generation (RAG) architectures that combine Qdrant vector stores, function calling, metadata-aware re-ranking, and multi-step agentic workflows. I construct knowledge bases from structured and unstructured data, carefully optimizing chunking, ingestion, and evaluation to minimize hallucinations and maximize answer quality. I deploy and optimize models such as Gemma3, Qwen, LLaMA, and Mistral using vLLM for high-throughput, low-latency inference. My expertise includes batching, KV-cache tuning, async streaming, GPU memory control, and CUDA-level performance tuning, enabling robust token-by-token streaming pipelines for text and voice AI applications. I build backend AI services with Python, FastAPI, or Flask, seamlessly integrated with vector databases and external APIs. I troubleshoot slow inference, retrieval inaccuracies, hallucinations, and scaling issues, transforming underperforming systems into stable production platforms. Recent projects include integrating Gemma3 with Qdrant for high-accuracy multi-step RAG, creating function-calling pipelines where LLMs autonomously query tools and generate HTML-ready outputs, and developing bilingual Amharic-English AI assistants. I also optimize local and offline LLM deployments for predictable production-grade performance. If you need an AI engineer who handles everything from model behavior to retrieval pipelines to inference serving, I can help you turn AI prototypes into reliable production systems that scale and deliver.
