A black and white poster with a circular design on it

Design a programming logo that embodies the essence of 'Soteria Development.' Incorporate elements that represent both programming and the concept of 'Soteria,' which typically signifies safety, security, or deliverance. Utilize a modern and sleek design, combining clean lines and subtle details. Integrate coding symbols like brackets, semicolons, or code snippets, creatively merging them with imagery associated with protection or progress. Employ a color palette that resonates with both technology and trust, such as a blend of cool blues and polished greys. The logo should reflect the synergy of software development and the assurance conveyed by the name 'Soteria Development'.
