EXHIBIT 31.1

SECTION 302  CERTIFICATION  OF CHIEF EXECUTIVE  OFFICER AND PRINCIPAL  FINANCIAL
OFFICER OF DTOMI, INC.

I, John Haddock, certify that:

1.       I have reviewed this quarterly report of Form 10-QSB of Dtomi, Inc.;

2.       Based on my  knowledge,  this  quarterly  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 quarterly report;

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

4.       I am responsible for establishing and maintaining  disclosure  controls
         and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for
         the registrant and we have:

          a.   designed such disclosure controls and procedures to ensure that
               material information relating to the registrant, including its
               consolidated subsidiaries, is made known to us by others within
               those entities, particularly during the period in which this
               quarterly report is being prepared;

          b.   evaluated the effectiveness of the registrant's disclosure
               controls and procedures as of a date within 90 days prior to the
               filing date of this quarterly report (the "Evaluation Date"); and

          c.   presented in this quarterly report our conclusions about the
               effectiveness of the disclosure controls and procedures based on
               our evaluation as of the Evaluation Date;

5.       The registrant's other certifying officers and I have disclosed,  based
         on our most recent  evaluation,  to the  registrant's  auditors and the
         audit  committee  of  registrant's   board  of  directors  (or  persons
         performing the equivalent function):

          a.   all significant deficiencies in the design or operation for
               internal controls which could adversely affect the registrant's
               ability to record, process, summarize and report financial date
               and have identified for the registrant's auditors any material
               weakness in internal controls; 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; and

6.       The registrant's other certifying officers and I have indicated in this
         quarterly  report  whether  or not there  were  significant  changes in
         internal  controls  or in other facts that could  significantly  affect
         internal controls subsequent to the date of our most recent evaluation,
         including any corrective action with regard to significant deficiencies
         and material weaknesses.
