Deep dive with our tech lead

At Freeday, we’re at the forefront of a thrilling transformation in how businesses engage with customers, manage compliance, and streamline financial processes. I’m Nemanja, Tech Lead at Freeday, and I have the privilege of guiding a talented team of engineers in creating innovative AI solutions that drive this change. In this blog, I want to take you behind the scenes to share some insights into what we do, how we do it, and why it matters.

Turning vision into reality

One of the most exciting aspects of my role is seeing ideas turn into real, impactful software. At Freeday, our focus is on developing AI solutions that enhance customer service, streamline Know Your Customer (KYC) processes, and optimize Accounts Payable systems. Our journey begins with close collaboration with our product team, where we transform business concepts into solid technical designs. This meticulous planning stage ensures that when we start coding, we’re on the right track to deliver high-quality software that meets our customers’ needs.

Quality is at the heart of everything we do. Before we write even a single line of code, we have a detailed plan in place. This involves making sure our software is not only functional but also scalable and maintainable. We rely heavily on automated tests and industry best practices to uphold a high standard of quality in every product we build. Seeing our hard work make a tangible difference for our customers is incredibly rewarding. I’m particularly excited about the potential of AI to revolutionize customer service, especially through channels like email, messaging apps, and voice interactions.

Collaboration is key

Building effective AI solutions is never a solo effort—it’s a team endeavor. The first step in our process is understanding exactly what we need to build. We work closely with our product team, engaging in deep discussions to explore every angle and ensure we’re addressing all potential gaps. These conversations are crucial, leading to robust and well-rounded solutions.

Once we’ve aligned on what needs to be done, our team of engineers comes together to discuss the technical design. This stage goes beyond just writing code; it’s about determining where and how that code will live within the system, what infrastructure it requires, and how everything will fit together. After we’ve ironed out these details, we move into the development phase, maintaining rigorous standards through peer reviews, documentation, and extensive testing.

"Collaboration is key to turning vision into reality."

As a Tech Lead, my role is to ensure that this entire process runs smoothly. This often means providing support wherever needed and facilitating the kind of back-and-forth that helps us refine our approach. Our team’s collaborative spirit is one of our greatest strengths, and it’s this teamwork that enables us to overcome challenges and deliver high-quality products.

Ethics and accuracy in AI

In the world of AI, ensuring that models are ethical, accurate, and free from bias is critical. At Freeday, we take this responsibility seriously. While the AI models we use come with built-in guardrails to prevent unethical outcomes, we don’t stop there. We implement additional safeguards to tailor the AI’s behavior to our customers’ specific needs—whether it’s maintaining the right tone of voice or following specific protocols.

"In AI, ethics and accuracy are non-negotiable."

A key factor in this is the quality of data. Our customers provide a lot of documents, and we preprocess these to ensure our AI models are working with the most relevant information. We’ve also implemented extensive automated testing to continuously verify the accuracy and trustworthiness of our system’s responses. This ensures that as our software evolves, it continues to perform reliably and ethically.

Innovation and the path ahead

The pace of innovation in AI is nothing short of astonishing. Compared to just a few years ago, AI models today are faster, more accurate, and capable of processing larger volumes of data. This progress has made our work both easier and more complex. On one hand, reduced complexity in some areas allows us to focus on integrating AI with more tools, which brings its own set of challenges. On the other hand, we need to ensure that our solutions remain scalable as demand grows.

"Our modular system design allows us to scale solutions piece by piece."

To meet these challenges, we’ve designed our system in a modular way, allowing us to scale our solutions piece by piece. This flexibility is crucial as we anticipate the need for our digital employees to interact with more tools—and even with other digital employees—in the future.

Overcoming challenges and looking to the future

One of the biggest challenges we’ve faced was improving the speed of our chatbots. Early on, our bots were slow, which led to a less-than-ideal user experience. We tackled this by optimizing our system and using faster AI models, significantly improving response times. Hearing positive feedback from our customers after these changes was incredibly gratifying.

Looking ahead, I believe AI will continue to be a game-changer, not just in customer service but across many industries. I envision a future where digital assistants communicate with each other to handle complex tasks—whether that’s organizing a holiday, managing financial reports, or handling customer queries. The possibilities are endless, and I’m excited to see where this journey takes us.

"We’re not just building software; we’re building the future of work."

At Freeday, we’re not just building software; we’re building the future of work. And I, for one, can’t wait to see what’s next.
