The col­la­bo­ra­ti­on with Com­pu­ter­BUT­LER was a tur­ning point for our com­pa­ny. We were par­ti­cu­lar­ly impres­sed: The deve­lo­pers did­n’t just pro­gram, they actively thought along with us and sug­gested solu­ti­ons that we had­n’t even had on our radar. The result is a high-per­for­mance cus­to­mer por­tal that has revo­lu­tio­ni­zed our ser­vice pro­ces­ses and increased cus­to­mer satis­fac­tion by 37%.

The team not only deli­ver­ed our com­plex e‑commerce plat­form on time, but also excee­ded all per­for­mance tar­gets. The con­ver­si­on rate has increased by 28% and cart aban­don­ment has decreased by 42%. The invest­ment has alre­a­dy paid for its­elf after 9 months.

What sets Com­pu­ter­BUT­LER apart from others is the excep­tio­nal qua­li­ty of the code and the holi­stic IT approach. As a tech-sav­vy com­pa­ny, it was important for us to get a clean, well-docu­men­ted code base that we could deve­lop fur­ther our­sel­ves. That’s exact­ly what we got — plus a 67% increase in the per­for­mance of our appli­ca­ti­on.

    Secu­ri­ty & com­pli­ance — our pro­mi­se

    In a time of incre­asing digi­tal thre­ats and strict data pro­tec­tion requi­re­ments, secu­ri­ty is not an optio­nal fea­ture, but a basic requi­re­ment. We imple­ment com­pre­hen­si­ve secu­ri­ty mea­su­res at all levels — from code qua­li­ty to ser­ver infra­struc­tu­re — to opti­mal­ly pro­tect your appli­ca­ti­ons and data. We take indus­try-spe­ci­fic com­pli­ance requi­re­ments into account and inte­gra­te secu­ri­ty as a fun­da­men­tal part of our deve­lo­p­ment pro­cess.

    Hig­hest per­for­mance for your soft­ware appli­ca­ti­ons

    Opti­mum speed and sca­la­bi­li­ty are decisi­ve fac­tors for the suc­cess of your digi­tal appli­ca­ti­ons. With our cus­to­mi­zed per­for­mance opti­miza­ti­ons, we ensu­re that your APP solu­ti­ons func­tion quick­ly and relia­bly even under high load. Through a holi­stic opti­miza­ti­on approach — from the front end to the back end to the infra­struc­tu­re — we crea­te appli­ca­ti­ons that delight your users and sup­port your busi­ness goals.

    Front-end opti­miza­ti­on

    We opti­mi­ze your appli­ca­ti­on for the best user expe­ri­ence with a focus on core web vitals. We acce­le­ra­te the initi­al loa­ding time through pro­gres­si­ve ren­de­ring and code split­ting. Our effi­ci­ent asset manage­ment includes image opti­miza­ti­on and CSS/JS mini­miza­ti­on. With Cri­ti­cal CSS, we ensu­re fast initi­al ren­de­ring, while lazy loa­ding for images and non-cri­ti­cal con­tent impro­ves over­all per­for­mance.

    Backend opti­miza­ti­on

    In the backend, we rely on effi­ci­ent data­ba­se queries with opti­mal index­ing for maxi­mum speed. Query caching and pre­pared state­ments signi­fi­cant­ly redu­ce the ser­ver load. Resour­ce-inten­si­ve tasks are pro­ces­sed asyn­chro­no­us­ly, while our micro­ser­vices archi­tec­tu­re ensu­res out­stan­ding sca­la­bi­li­ty. This is roun­ded off by effi­ci­ent memo­ry manage­ment for opti­mum resour­ce uti­liza­ti­on. 
    // Performance optimization framework - sample code

// 1. frontend optimization
class FrontendOptimizer {
  constructor() {
    this.criticalCSSLoaded = false;
    this.lazyImages = document.querySelectorAll('[data]');
  }
  
  // Critical CSS for fast initial display
  loadCriticalCSS() {
    const criticalStyles = document.createElement('style');
    criticalStyles.innerHTML = 'body{opacity:1}';
    document.head.appendChild(criticalStyles);
    this.criticalCSSLoaded = true;
  }
  
  // Lazy loading for images
  initLazyLoading() {
    const observer = new IntersectionObserver((entries) => {
      entries.forEach(entry => {
        if (entry.isIntersecting) {
          const img = entry.target;
          img.src = img.dataset.src;
          observer.unobserve(img);
        }
      });
    });
    this.lazyImages.forEach(img => observer.observe(img));
  }
}

    Caching stra­te­gies

    We imple­ment mul­ti-level caching con­cepts at all levels (brow­ser, CDN, appli­ca­ti­on, data­ba­se) for maxi­mum per­for­mance. We use Redis/Memcached effec­tively for ses­si­on and data caching. Sta­tic con­tent is acce­le­ra­ted by full page caches, while dyna­mic are­as bene­fit from frag­ment caching. Our edge caching solu­ti­ons via CDN ensu­re glo­bal avai­la­bi­li­ty with mini­mal loa­ding times.

    Sca­la­bi­li­ty

    Your appli­ca­ti­on grows with your suc­cess: our hori­zon­tal and ver­ti­cal sca­ling con­cepts ensu­re that per­for­mance is gua­ran­teed even with incre­asing user num­bers. With load balan­cing and auto-sca­ling, we auto­ma­ti­cal­ly adapt resour­ces to demand. Con­tai­ne­riza­ti­on with Docker and Kuber­netes makes the infra­struc­tu­re fle­xi­ble and main­tainable. We rely on data­ba­se shar­ding for lar­ge amounts of data, while our micro­ser­vices archi­tec­tu­re ensu­res func­tion­al sca­ling.

We rely on a mul­ti-stage QA pro­cess: auto­ma­ted tests (unit, inte­gra­ti­on and end-to-end tests), con­ti­nuous inte­gra­ti­on (CI/CD), sys­te­ma­tic code reviews by seni­or deve­lo­pers and com­pre­hen­si­ve manu­al tests. Befo­re release, each pro­ject under­goes a struc­tu­red accep­tance pro­cess with detail­ed check­lists for func­tion­a­li­ty, per­for­mance, secu­ri­ty, acces­si­bi­li­ty and brow­ser com­pa­ti­bi­li­ty. This pro­ce­du­re ensu­res that your PHP appli­ca­ti­on works relia­bly and meets the hig­hest qua­li­ty stan­dards.
    PHP sup­port and main­ten­an­ce
    As a local­ly based PHP agen­cy Ber­lin, we offer com­pre­hen­si­ve sup­port and main­ten­an­ce ser­vices for your PHP appli­ca­ti­ons. Our ser­vices include regu­lar updates and secu­ri­ty patches, per­for­mance moni­to­ring and opti­miza­ti­on, data back­up, tech­ni­cal sup­port and trou­ble­shoo­ting. Depen­ding on your requi­re­ments, you can choo­se bet­ween dif­fe­rent ser­vice levels — from basic main­ten­an­ce to com­pre­hen­si­ve 24/7 sup­port with gua­ran­teed respon­se times. Most of our Ber­lin cus­to­mers choo­se a month­ly main­ten­an­ce packa­ge to ensu­re the long-term sta­bi­li­ty and secu­ri­ty of their PHP appli­ca­ti­ons.
    PHP per­for­mance opti­miza­ti­on
    As an expe­ri­en­ced PHP agen­cy in Ber­lin, we are experts in per­for­mance opti­miza­ti­on. We ana­ly­ze your exis­ting PHP appli­ca­ti­on holi­sti­cal­ly and iden­ti­fy bot­t­len­ecks at all levels: from code qua­li­ty and data­ba­se queries to ser­ver con­fi­gu­ra­ti­on and the front end. Our opti­miza­ti­ons include effi­ci­ent caching (Redis, Mem­cached), data­ba­se opti­miza­ti­on, code refac­to­ring, resour­ce mini­miza­ti­on and CDN inte­gra­ti­on. The­se mea­su­res typi­cal­ly lead to speed impro­ve­ments of 50–300% and signi­fi­cant­ly bet­ter sca­la­bi­li­ty — important fac­tors for con­ver­si­on opti­miza­ti­on and user satis­fac­tion.
    PHP secu­ri­ty and com­pli­ance
    Secu­ri­ty is an inte­gral part of every PHP deve­lo­p­ment at our Ber­lin agen­cy. We imple­ment com­pre­hen­si­ve safe­guards against com­mon thre­ats such as SQL injec­tion, XSS, CSRF and other OWASP Top 10 risks. Our deve­lo­pers fol­low the Prin­ci­ple of Least Pri­vi­le­ge, imple­ment secu­re authen­ti­ca­ti­on and aut­ho­riza­ti­on and ensu­re GDPR-com­pli­ant data pro­ces­sing. Regu­lar secu­ri­ty audits, auto­ma­ted vul­nerabi­li­ty scans and pene­tra­ti­on tests ensu­re that your PHP appli­ca­ti­on is per­ma­nent­ly pro­tec­ted against cur­rent thre­ats.
    PHP migra­ti­on and moder­niza­ti­on

We start by ana­ly­sing your exis­ting code, deve­lop a tail­or-made migra­ti­on stra­tegy and car­ry out the chan­geo­ver step by step in a risk-mini­mi­zing man­ner. This moder­niza­ti­on not only impro­ves the per­for­mance and secu­ri­ty of your appli­ca­ti­on, but also redu­ces long-term main­ten­an­ce cos­ts and enables the inte­gra­ti­on of modern func­tions and tech­no­lo­gies.
