Honestly, the first IT specialist in 12 years of my professional career who is this easy and pleasant to communicate with! Everything is clear and understandable, without unnecessary technical jargon, and tasks are done not only professionally but also incredibly fast.
From the client's side, everything feels simple and smooth – there's no need to explain at length, wait, or rack your brain. We simply agree, and the work is done!
I'm so glad I found a specialist like this! I sincerely recommend him to anyone who needs a reliable, professional, and people-oriented IT specialist! 👏

Realiai, pirmasis IT specialistas per 12 metų mano profesinėje praktikoje, su kuriuo taip paprasta ir lengva bendrauti! Viskas aišku, suprantama, be bereikalingo techninio žargono, o užduotys atliekamos ne tik profesionaliai, bet ir neįtikėtinai greitai.
Iš kliento pusės viskas atrodo paprasta ir sklandu – nereikia ilgai aiškinti, laukti ar sukti galvos. Tiesiog susitariame ir darbai padaryti!
Labai džiaugiuosi atradusi tokį specialistą! Nuoširdžiai rekomenduoju kiekvienam, kam reikia patikimo, profesionalaus ir į žmogų orientuoto IT specialisto! 👏
Working with Tadas was a truly great experience. Having worked with various programmers in the past—the first version of our website was started over a year ago, so I have had all kinds of experiences. I tried reaching out to advertising agencies as well as freelancers in Facebook groups, but Tadas’s responses immediately stood out—detailed, clear, and showing genuine attention to my needs.
The work went very smoothly—the website was built on time, and the final result exceeded expectations, including additional features we had not initially planned. I sincerely recommend Tadas to anyone looking for a reliable and responsible professional 🙂
Dirbti su Tadu buvo tikrai puiki patirtis. Esu bendravusi su įvairiais programuotojais – pirmasis puslapio variantas buvo pradėtas dar prieš daugiau nei metus, tad per tą laiką teko susidurti su visokiomis patirtimis. Bandžiau kreiptis ir į reklamos agentūras, ir į freelancerius iš „Facebook“ grupių, bet Tado atsakymai iškart išsiskyrė – išsamūs, aiškūs ir su tikru dėmesiu mano poreikiams.
Darbas vyko labai sklandžiai – svetainė buvo sukurta laiku, o galutinis rezultatas net pranoko lūkesčius: atsirado ir papildomų funkcijų, kurių iš pradžių nebuvome numatę. Nuoširdžiai rekomenduoju Tadą visiems, kas ieško patikimo ir atsakingo specialisto 🙂
Tadas contributed greatly to the improvement of our existing website—he quickly grasped the current situation, clearly assessed what was missing, and promptly got to work. He completed the tasks quickly and with high quality, and communication throughout the process was smooth and straightforward.
Not only did he resolve the issues presented, but he also proactively proposed additional improvements and implemented them effectively. Truly a reliable and professional developer.
Tadas puikiai prisidėjo prie mūsų jau veikiančio puslapio tobulinimo - greitai perprato esamą situaciją, aiškiai įvertino, ko trūksta, ir operatyviai ėmėsi darbų. Užduotis atliko greitai ir kokybiškai, o bendravimas viso proceso metu buvo sklandus ir paprastas.
Jis ne tik išsprendė pateiktas problemas, bet ir savo iniciatyva pasiūlė papildomų patobulinimų, kuriuos efektyviai įgyvendino praktikoje. Tikrai patikimas ir profesionalus programuotojas.
