Wacera Profile

Hello, I'm Mercy Wacera

Software Developer • Cybersecurity & AI Enthusiast

About Me

Hi, I'm a creative and security-conscious Software Developer passionate about building transformative technology.

I have solid experience in Object-Oriented Software Development, designing scalable and maintainable systems with clear architecture and reusable components. I apply these principles across multiple languages including C#, Java, and Go.

I’m experienced in full-stack web programming, with a strong foundation in cloud computing, computer networks, and cybersecurity. I’m also exploring the exciting world of artificial intelligence and how it can solve real-world challenges.

Fintech Experience @ Jambopay

I’ve worked on mission-critical fintech systems using:

  • .NET Core & ASP.NET // C#
  • Go (Golang)

Key projects include:

  • Wallet Reports – Analyzing digital wallet transactions
  • CBK Service – Connecting with Central Bank of Kenya systems
  • Merchant Client Portal – A portal for business clients to manage operations securely

My work combines technical skill, a deep understanding of secure systems, and a commitment to inclusive, innovative development. Beyond code, I'm passionate about empowering women in STEM and creating inclusive tech communities. Whether it’s mentoring, or collaborating with mission-driven teams — I love using technology to uplift and inspire.

Let's build the future, securely and creatively.
