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.
