Procurement Tactics • Freelance

Jan 2021 - Present • 5 yrs 4 mos

I provide professional tender writing and bid support services across a range of sectors, including public and private procurement. I specialise in preparing high-quality, compliant submissions in response to ITTs, RFPs and PQQs, ensuring alignment with client requirements and evaluation criteria. My work involves analysing tender documentation, developing structured and persuasive responses, and clearly articulating value propositions, methodologies, and social value commitments. I have experience interpreting complex specifications, coordinating with stakeholders to gather technical input, and ensuring submissions are completed accurately and on time. Key achievements include improving bid success rates through tailored responses, strong attention to detail, and effective use of evidence-based writing. I am confident in working with frameworks such as Crown Commercial Service and other UK procurement portals, and I maintain a thorough understanding of procurement regulations and compliance standards. I am highly organised, deadline-driven, and committed to delivering clear, concise, and compelling tender documents that enhance clients’ chances of success.
