I,
      Nora
      Coccaro, Chief Executive Officer and Chief Financial Officer of Sona Development
      Corp (“Registrant”) certify that:




1.    
      I have reviewed this Annual Report on Form 10-KSB (“Report”) of Registrant;




2.    
      Based on my knowledge, this Report does not contain any untrue statement of
      a
      material fact or omit to state a material fact necessary to make the statements
      made, in light of the circumstances under which such statements were made,
      not
      misleading with respect to the period covered by this Report;




3.    
      Based on my knowledge, the financial statements, and other financial information
      included in this Report, fairly present in all material respects the financial
      condition, results of operations and cash flows of the Registrant as of, and
      for, the period presented in this Report;




4.    
      I am responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-15(e)) and internal control
      over financial reporting (as defined in Exchange Act Rules 13-a-15(f) and
      15d-15(f)) for the Registrant and have:




a)    
      Designed such disclosure controls and procedures, or caused such disclosure
      controls and procedures to be designed under my supervision, to ensure that
      material information relating to the Registrant is made known to me by others
      within those entities, particularly during the period in which this Report
      is
      being prepared;




b)
      Designed such internal control over financial reporting, or caused such internal
      control over financial reporting to be designed under my supervision, to provide
      reasonable assurance regarding the reliability of financial reporting and the
      preparation of financial statements for external purposes in accordance with
      generally accepted accounting principals;




c)    
      Evaluated the effectiveness of the Registrant’s disclosure controls and
      procedures and presented in this Report my conclusions about the effectiveness
      of the disclosure controls and procedures, as of the end of the period covered
      by this Report based on such evaluation; and




d)    
      Disclosed in this Report any change in the Registrant’s internal control over
      financial reporting that occurred during the Registrant’s most recent fiscal
      quarter (the Registrants fourth fiscal quarter in the case of an annual report)
      that has materially affected, or is reasonably likely to materially affect,
      the
      Registrant’s internal control over financial reporting; and







5.    
      I have disclosed, based on my most recent evaluation of internal controls over
      financial reporting, to the Registrant’s auditors and the audit committee of
      Registrant’s board of directors (or persons performing the equivalent
      functions):




a)    
      All significant deficiencies and material weaknesses in the design or operation
      of internal controls over financial reporting which are reasonably likely to
      adversely affect the Registrant’s ability to record, process, summarize and
      report financial information; and




b)    
      Any fraud, whether or not material, that involves management or other employees
      who have a significant role in the Registrant’s internal controls over financial
      reporting.




Date:
      April 2, 2007
