Teresa G.

Data Entry & Excel Support | Data Analyst in Training

Porto, Portugal
$15 per hour
4 jobs
$100+ total earnings

Hello! My name is Teresa and I’m a Portuguese native speaker, living in Portugal. I hold a Master’s degree in Bioengineering and a PhD in Chemical and Biological Engineering. My academic and research background has provided me with strong analytical skills, a highly structured way of thinking, and extensive experience working with complex data sets. Throughout my scientific training, I developed a strong attention to detail, critical thinking, and the ability to extract meaningful insights from experimental and technical data. I am comfortable working in data-intensive environments where accuracy, logic, and structure are essential. I am currently expanding my skills in Data Analysis, with training in Excel, SQL, and Python, and I am particularly interested in data cleaning, data organization, and analytical problem-solving. I am now looking for opportunities where I can apply my scientific and analytical background to real-world data tasks, while continuing to develop professionally in the field of data analysis. Hope you consider my application!

Erfan A.

Academic Proofreader & Reviewer | Mechanical Engineering

Porto, Portugal
$15 per hour
1 job
$23 total earnings

I am a postdoctoral researcher with a solid background in computational mechanics, specializing in finite element analysis (FEA), numerical modeling, fracture mechanics and related topics. I have authored 12 publications in high-impact journals, accumulated 300+ citations, and served as a peer reviewer for reputed journals in the field. What I do best: • Proofreading & Editing academic and technical manuscripts (journal articles, conference papers, reports) • Improving clarity, grammar, and structure while maintaining technical accuracy • Providing expert review and feedback on methodology, results, and presentation (e.g., Figures, Tables) • Ensuring compliance with major journal guidelines (APA, ABNT, IEEE, etc.) If you are preparing a journal article, conference paper, or research report in mechanical engineering, I can help refine your work to meet top academic standards.

Melina D.

Biologist - Scientific writing, literature review & R/SPSS

Albufeira, Portugal
$18 per hour
1 job
$55 total earnings

Biologist with a Bachelor’s and Master’s degree in Biotechnology and currently a PhD candidate in Biological Sciences, with research experience in Portugal, Greece and Macao. Experienced in molecular biology, animal behaviour, aquaculture and statistics, with peer‑reviewed publications as first author in journals such as Journal of Fish Biology, Scientia Horticulturae, Phytoparasitica and Acta Ethologica. I completed a scientific writing course and have experience teaching university laboratory classes and supervising students, including supporting thesis writing and correction. I am used to preparing material for publication, from structuring manuscripts and improving language to adapting figures, tables and references to journal guidelines. I also work with data analysis in R and SPSS for experimental and survey data, producing descriptive statistics, basic tests and clear tables and plots. I have presented my work at national and international conferences and was awarded a doctoral research grant from the Portuguese Foundation for Science and Technology (FCT) and an Erasmus traineeship grant.

Dany D.

PhD Bioinformatician | RNA-seq · Proteomics · NGS · Pipeline Dev

Porto, Portugal
$75 per hour
11 jobs
$800+ total earnings

I am a PhD bioinformatician with over a decade of hands-on experience transforming raw biological data into publication-ready results. My work sits at the intersection of molecular OMICs, computational biology, and applied biodiscovery — and I bring that same rigor to every freelance engagement. My background spans the full NGS pipeline stack: de novo transcriptome assembly, bulk and single-cell RNA-seq, shotgun proteomics, proteogenomics, phylogenetics, and bioactive peptide discovery. I am particularly experienced with non-model and marine organisms — a genuinely rare specialization that most bioinformatics labs lack in-house. A few highlights that set me apart: — Published tool developer. I am the author of SeqLengthPlot v2.0 (Bioinformatics Advances, 2024), a widely-used FASTA sequence visualization tool, and FiltDeTox, a Python tool for filtering and validating toxin candidates in venomics pipelines. I don't just run pipelines — I build them. — 23 peer-reviewed publications · 455 citations (Google Scholar, checked Aug 2026). My work has appeared in ACS Omega, Toxins, npj Biofilms & Microbiomes, IJMS, and Frontiers in Microbiology. I know what publication-quality analysis looks like, and I deliver exactly that. — Private HPC infrastructure. I run analyses on a dual-node Xeon workstation (160 threads, 384 GB RAM, 9 TB storage), which means I can handle large datasets — whole-genome assemblies, large-scale proteomics runs, multi-sample RNA-seq cohorts — without cloud compute costs passed on to you. — Research Fellow, Stazione Zoologica Anton Dohrn, Naples (2024–2026, concluded January 2026). Most recently I led proteotranscriptomic characterization of deep-sea cnidarian venoms within the CRIMAC DEEPVEN project funded by the Italian Ministry of University and Research. What I can do for you: - RNA-seq analysis (bulk, single-cell, de novo assembly, differential expression, pathway enrichment) - Proteomics and proteogenomics (MaxQuant, Perseus, FragPipe, R-based downstream analysis) - NGS pipelines (WGS, WES, variant calling, genome assembly) - Bioactive peptide and AMP discovery (in silico, end-to-end) - Phylogenetic and evolutionary analysis (IQ-TREE, BEAST, molecular clocks) - Custom Python/R/Bash pipeline development - Scientific writing, manuscript editing, and data interpretation I work in English, Spanish, and Portuguese — which is a practical advantage if your team or collaborators operate in Iberia or Latin America. I deliver clean, documented, reproducible analyses. If you share your data and a clear goal, I take it from there.
