I'm a senior GIS and AI specialist. I build full geospatial and agent/LLM/ML/CV stacks, from the sensor design and data pipelines, to the central AI, and finally to the things your users touch. I hold a degree in Geography, have deep experience in Applied Artificial Intelligence, I work in ArcGIS Pro, QGIS, PostGIS, and Python. Demos below. Here's what full-stack means in practice. Hand me a question like "what's on this land, and can we build on it," and I can plan the imagery and sensing, write the pipeline that pulls and cleans the data, train the computer vision model that reads it, run the spatial analysis in PostGIS, put an LLM agent over the top that turns the raw findings into a plain answer and takes the next action, and then ship the answer three ways: an interactive web map, a mobile app, and a print-ready sheet at 300 DPI. That's one person handling the whole chain. What I build: - The full ML and computer vision stack. Labeling and training data, a model that detects or segments objects in satellite, aerial, and drone imagery, and an accuracy number I can defend. A couple of my demos run a trained model live in your browser. - AI apps and agents. LLM-backed tools on the OpenAI, Claude, and Gemini APIs: retrieval over your own documents, agents that call tools and take actions, scraping and enrichment pipelines, and Python engineering apps and platforms (VIKTOR, etc). Structured outputs I can trust in production, not a demo that falls over on real data. - Data pipelines and sensing strategy. What to collect and how to collect it, then the ingest, cleaning, and scraping that keeps the data current. - GIS and spatial analysis. ArcGIS Pro, QGIS, and PostGIS for cartography, heavy spatial analysis, and parcel or territory or site-selection work with an audit trail you can follow. - Dashboards, websites, and mobile apps. The interactive map, dashboard, site, or app your team and your customers open every day, built on real data you can check. - Print cartography. Journal-ready and boardroom-ready maps, georeferenced, at full print resolution. Where the "senior" part shows up: I have spent the last 4 years being hired by firms with complex geospatial needs and working in capacities from C-Suite collaborator to specialists team member. Companies I have managed for have raised hundreds of millions in venture funding, shipped thousand projects, and my team in my last role did over $4M of work here on Upwork. How I work: Some jobs are a clean fixed scope. Others run better as a monthly retainer while I sit alongside your team or manage it. Tell me what you're trying to make, and I'll suggest the setup that fits. Got a complex geospatial or AI build that needs more than one specialty in one head? Send me a note, and open the demos while you're deciding.

What does an astronomer do?

An astronomer studies celestial objects and phenomena to understand the physical universe through observation and analysis. This role involves collecting data from telescopes or archives, processing that information with specialized software, and interpreting the results to test scientific hypotheses. Astronomers build models of cosmic events and share their findings with the scientific community through detailed reports and presentations.

  • Plan and execute observational studies or retrieve archival data from astronomical databases to investigate specific celestial phenomena. Process raw data using mission-specific tools like FTOOLS or HEASoft to reduce noise and extract measurable signals such as spectra or light curves.
  • Analyze processed datasets to test theoretical models and derive quantitative results about astronomical objects. Run scientific analyses to identify patterns, validate findings through reproducible steps, and refine instrumentation or methods based on the outcomes.
  • Document scientific results in research papers, technical reports, or theses for publication in peer-reviewed journals. Prepare and deliver presentations that summarize methods and conclusions for academic audiences, ensuring complex data is communicated clearly and accurately.

How to hire an astronomer on Upwork

Step 1: Post a job

Define your research goals and data requirements clearly to attract qualified scientists. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description. Describe your needs in a few sentences, and Uma drafts a job post for the role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify whether you need observational analysis, theoretical modeling, or instrument development support.
  • List required software proficiency, such as FTOOLS, HEASoft, or Hera for high-energy astrophysics data.
  • Detail the type of celestial phenomena or archival datasets the freelancer will process and interpret.
