Hi there! 👋 If you’re looking for someone who can turn your repetitive, time-consuming tasks into smart, self-running systems that deliver compounding value, you’re in the right place. I specialize in building reliable, real-world automations with n8n and Make that don’t just work today, they keep saving you time, reducing errors, and scaling with your business month after month. ✅ Automations that compound value over time—saving more hours each month ✅ Reduce human error in lead follow-up, data entry, and customer comms ✅ Free your team to focus on high-value work, not repetitive tasks ✅ Fast onboarding + minimal training needed for your team to take over Here’s what I build: • AI-powered lead engines: Auto-discover, enrich, score, and route leads from Google Maps, Typeform, or webhooks fully automated in n8n • Smart AI agents: Handle internal Q&A, data processing, and lead routing using LLMs + structured workflows • Content automation: Generate blogs, social posts, newsletters, and product descriptions via n8n + OpenAI/Gemini • Voice & chat assistants: Task-executing bots on WhatsApp, Telegram, or web for scheduling, research, and alerts • Low-code RAG systems: Deliver accurate, citation-backed answers using n8n + OpenAI/Gemini + Pinecone/Qdrant • CRM & ops sync: Seamless data flow between Airtable, Google Workspace, Slack, Sheets, and custom APIs • Document intelligence: Parse PDFs, emails, and forms extract, structure, and store clean, actionable data Tools I use daily: n8n, Make, Apify, OpenAI, Google Gemini, Pinecone, Qdrant, Airtable, Gmail, Google Calendar, Telegram, JavaScript, REST APIs I don’t just connect apps, I design automation systems that become force multipliers for your team. If this sounds like what you need, send me a message with your goal. Let’s build something that actually runs itself and keeps getting better over time.

I evaluate and train AI systems for companies building language models, and I build the software that supports that work. I split my time between AI evaluation/annotation and full-stack development, and most of my recent client work sits at the intersection of the two: technical enough to actually understand what I'm evaluating, hands-on enough to build the systems around it. AI Evaluation & Task Authoring At Revelo, I build compliant benchmark tasks for Terminal Bench 2, a coding benchmark used to test frontier models like Claude and GPT. Each task includes an instruction file, a Dockerized test environment, a full test suite, and a golden solution. The hard part isn't writing the task itself, it's designing environmental complexity that actually challenges strong models instead of relying on artificial difficulty. I've also worked on Project Claw in the same vein, and I spend a fair amount of time troubleshooting local validation loops so tasks pass cleanly before submission. Through Turing, Outlier, and AfterQuery, I evaluate LLM responses, rank model outputs, and author technical assessment tasks. One recent project involved converting real security vulnerabilities into gradable benchmark tasks (vulnerability-to-benchmark conversion), which required understanding both the exploit and how to structure it as something a model could be fairly tested against. I've also completed technical exams covering Docker environments, golden solution design, and agentic trace evaluation, so I know what reviewers look for on the other side of the process. Data Annotation I do bilingual NLP annotation, Amharic and English, most recently through RWS Group's Echo 2026 project. Amharic-language data work is genuinely scarce on most platforms, and I bring both native fluency and the technical background to follow strict annotation guidelines without needing extra hand-holding. I've worked on image annotation, text classification, response ranking, and dataset structuring for downstream ML training. Software Development I build full-stack applications with Python, Django, Vue.js, and Flutter. Projects include StockWatch (a stock tracking app built with Django, Vue.js, and IEX Cloud), Smart Gebere (a Flutter app using AI-based crop disease detection for Ethiopian farmers, with Amharic, Oromo, and English support), and a full eCommerce platform. If you need AI features integrated into an existing product, API connections, model-backed workflows, automation, this is where my dev and AI-evaluation experience overlap most directly. Tools and technologies I work with regularly Python, Django, Vue.js, TypeScript, Flutter, PostgreSQL, Docker, Git, REST APIs, Firebase, and standard evaluation/annotation platforms used by AI training vendors. I pick up new internal tools fast since most annotation and eval work runs through platform-specific interfaces that vary by client. Background I graduated with a Computer Science degree from Adama Science and Technology University in 2022. Before that and since, I've done competitive programming through A2SV, with 400+ problems solved, which shaped how I think about edge cases and correctness, both as a developer and as someone designing tasks meant to catch models making mistakes. Why this combination matters for evaluation work A lot of annotation and evaluation work gets treated as low-skill, repetitive labeling. It isn't, not when it's done well. Understanding the code, the model behavior, or the underlying system being evaluated is what separates a task or label that actually improves a model from one that just adds noise to a dataset. I've been on both sides of this: writing the guidelines and following them, building the benchmark and grading against it. That's the perspective I bring to client work. How I work I read task instructions carefully before starting, ask clarifying questions early rather than guessing, and flag ambiguity in guidelines instead of quietly working around it. For dev work, I write code that's meant to be maintained, not just shipped. I'm available more than 30 hours a week and open to both short evaluation batches and longer contract-to-hire arrangements. What I take on: Data annotation and labeling (text, image, code, multilingual) LLM evaluation and response ranking Benchmark and task authoring (Docker-based environments, golden solutions) AI integration into existing software (API work, automation, model-backed features) Full-stack development (Python/Django backend, Vue.js/Flutter frontend) I communicate clearly, hit deadlines, and I'm comfortable working across Docker, Git, and whatever evaluation platform or workflow you're using. If you're not sure whether your project fits what I do, message me with the details and I'll give you a straight answer quickly, not a sales pitch.
