Manas.
Not literally. I build backend systems so reliable, you forget they exist. Currently turning clicks into bookings at Headout. Previously shipping trading infrastructure at Wissen Technology.
Seven years of making
complex things simple.
When millions of people book a sunset cruise in Santorini or skip-the-line tickets at the Louvre, my code is what makes it feel instant. I lead engineering at Headout, where every millisecond of latency is a booking lost — and I don't lose many.
Before that, I spent two years at Wissen Technology building trading systems where "move fast and break things" means something very different. That's where I learned to obsess over reliability, correctness, and the kind of code that lets you sleep at night.

The places that
shaped my craft.
Headout
Leading engineering for the B2B partner API platform — channel revenue grew 4x under my watch. Shipped Buy Now, Pay Later at checkout (+12% CVR). Built a fleet of MCP servers and an AI-agent-driven test suite to keep releases fast. Set up granular alerting so anomalies get caught before users do.
Owned the payments platform — 8 methods across 2 gateways, with an architecture that cut new integrations by 75% (1 week for methods, 3 for gateways). Built the intelligent routing engine that lifted auth rates 700 bps and cut costs ~8%. Dropped latency 60% on the highest-throughput product & inventory APIs.
Software Engineer
Wissen Technology- Built backend services for security transfers between brokers — the kind where a bug doesn't mean a bad UX, it means real money lost
- Designed a money market trading backend with automatic purchase and redemption, sourcing and validating financial data from multiple providers into a single clean feed
- Introduced TDD and automated deployments to a team that previously deployed manually. Bugs caught in staging went from "sometimes" to "almost always"
Technical Mentor
Newton School- Helped aspiring engineers crack the code — literally. Mentored on full-stack development, DSA, and the art of not panicking in interviews
What I bring
to the table.
Backend — where I live
Kotlin, Java, Spring Boot, jOOQ, Hibernate, gRPC, REST APIs, Microservices
Infrastructure — what keeps it running
Kubernetes, Docker, Kafka, AWS (EC2, S3, SQS, Lambda), Terraform, Gradle, CI/CD

Frontend — when needed
JavaScript, Next.js, HTML/CSS
Got an idea?
I've got the code.
Building something ambitious? Need someone who's done it at scale? Or just want to argue about Kotlin vs Go? I'm in.
