A Quick Introduction

I'm Robert, IT Consultant with special interest in IT Security. My professional strength is to provide full IT service from A to Z for small businesses and (start-up) entrepreneurs, because I have great expertise, deep technical understanding and passion and love in creating new structures and in reworking existing ones. I am also your professional Virtual Assistant for managing emails, make offers, satisfy customers, assist in traveling, write and blog, develop websites and manage social media channels. I am a generalist and keep an overview, but my insatiable appetite for technical things allows me to incorporate them quickly into new things.

  1. Christine Z., Esslingen


    Angenehm auffallend ist die hervorragende fachliche Kompetenz von Herrn Wallis in Kombination mit einem sehr angemessenen Preis-Leistungsverhältnis. Ebenso habe ich die Erfahrung gemacht, dass Herr Wallis sich sehr für die Kundenzufriedenheit engagiert und interessiert. Ich habe ihn mehrfach nach Abschluss des Auftrags anrufen können und immer wieder geduldig Auskunft erhalten.

  2. Dietmar Nanz, Esslingen


    Bei Herrn Wallis als IT-Experte finde ich mich als Privatkunde bestens aufgehoben. Probleme an IT-Einrichtungen werden von ihm prompt und freundlichst behoben. Sein Vor-Ort-Service ist beispielhaft.

  3. R. und G., Ostfildern


    Mit der Betreuung durch Herrn Wallis sind wir sehr zufrieden. Wir kauften bei ihm einen PC; auch bei kniffligen Problemen z. B. an unserer Telefonanlage forscht er nach den Ursachen und behebt diese zügig und zuverlässig. Vor allem erklärt er seine Arbeit so, dass die IT kein Buch mit sieben Siegeln für uns bleibt, sondern wir die technischen Abläufe gut nachvollziehen können. Wir freuen uns, einen kompetenten Ansprechpartner gefunden zu haben und werden gerne wieder auf ihn zurückgreifen.

  4. Andrea Haspel, Druck- & CopyCenter Esslingen


    Besonders für Unerfahrene ist ein neuer IT-Berater immer eine Vertrauenssache. Wird er mir mehr verkaufen als ich brauche? Ist er verfügbar, wenn ich ihn rufe? Bei Herrn Wallis bin ich sicher, dass er für jeden kleinen und mittleren Betrieb ein Gewinn ist. Bei mir nahm er nur kleine Änderungen am Netzwerk vor, installierte die Kunden-PCs neu und inzwischen ist unser DSL-Zugang durch einen Tarifwechsel schneller und günstiger geworden. Unsere Webseite wurde neu erstellt, so dass wir hervorragend gefunden werden. Auch in schwierigen Situationen war er sehr zügig verfügbar; eine enge Absprache ist mit ihm immer möglich. Vor allem berät er umfassend und denkt bei allen Optionen selbst mit.

  5. Hansjörg Durst, Esslingen


    Mein Einstieg in die Welt der EDV fing verhältnismäßig spät im Leben an. Entsprechend tat ich mich am Anfang [...] schwer [...]. So suchte ich jemanden, der mir die Materie plausibel erklären konnte und der vor allem zu mir nach Hause kam, um mir vor Ort zu helfen. Helfen wollten mir manche, aber zu nach Hause kommen wollte keiner. Da erhielt ich von einer Bekannten einen Tip. [...] So machte ich die Bekanntschaft von Herrn Robert Wallis. Er arbeitete mit der Bekannten bereits zusammen - zu ihrer vollen Zufriedenheit. Herr Wallis erklärte sich bereit, auch meinem Wunsch zu entsprechen, mir an meinem eigenen PC zu helfen. Auch seine finanziellen Bedingungen waren nicht überzogen. Ich kann sagen, besser hätte es nicht laufen können. Er hilft mir Probleme so zu lösen, dass ich es gut nachvollziehen kann. Ggf. gibt er mir seinen Rat auch schriftlich. Er unterstützt mich auch in der Beratung und beim Kauf neuer Geräte zu akzeptablen Preisen. Zusammengefasst kann ich sagen: Ich bin mit der Arbeit rundum zufrieden und kann ihn nur wärmstens weiterempfehlen.
