Hire the Best Software Architecture Freelancers in New York

Former Recruiter, Current Astrologer, Providing Career Search Support I'm here to support you in your career journey! I'll help you put your best foot forward with your new, improved resume! I used to do this exact gig and rewrote 60+ resumes and cover letters while working for Overheard Recruiting in 2020-21. I have 8 yrs of corporate work experience, mostly in recruitment and communications until I became self-employed in 2024. I joined Fiverr in 2025. I'm also an astrologer! I've been giving birth chart readings professionally since June 2024 after studying under a well-known professional for 4 years and completing an apprenticeship program. Unsurprisingly given my background, clients often come to me with career questions! If I were to sum up my employment history in one paragraph: The first year of my career I was a recruiter and business development specialist at a staffing agency in NYC. Next, I was a campus recruiter and internship and graduate program manager at a Wall Street Bank for 3.5 years. Then, I took a mental health break during the pandemic and found a part time job rewriting resumes, cover letters, and LinkedIn profiles! Following that, I returned to the full-time workforce in a program manager role wearing many hats at a hedge fund: I did internal communications, talent development, intranet management, vendor management, systems management, and business management. I particularly enjoyed writing scripts and blogs for leadership. When a third of my department got laid off, including me, I took it as a sign to pursue my passion, astrology, and other fulfilling self-employment endeavors. Lately, I've found fulfillment helping others on their career journey through writing resumes and giving career focused astrology readings.

How work according to a tried and true formula. 1. Outline the detail and scope of the project. 2. Establish our workflow, with an emphasis on open communication. 3. Dissect the project per logical unit. 4. For each unit: ... Produce deliverable. ... Subject to automated and acceptance testing. ... Submit for approval, refining as we go. ... Upon approval continue 5. Deliver the final. 6. Documentation if indicated 7. A period of refinement and support, typically a good will effort. This system establishes a pace that is both evident and finite, and produces well defined boundaries, with well defined deliverables, but leaving room to grow. All work is completed on deadline to client satisfaction.
