About Me

I build the systems that move money — and keep them standing.

Five years ago I was teaching PHP to a classroom of fifty students. Today I architect the payment rails, APIs and AI platforms that thousands of people depend on every day.

I'm a Senior Full Stack Developer at THESOFTKING Ltd., where I've shipped 50+ enterprise applications across fintech, e-commerce, SaaS and enterprise systems. My work lives where mistakes are expensive — crypto exchanges, digital banks, remittance corridors — so I design for security and uptime first, and everything else second.

That discipline shows up in the numbers: 15+ payment gateways integrated with zero security incidents, RESTful APIs serving 1M+ requests a day at 99.9% uptime, and MySQL work that cut query execution time by 40%.

I also lead. These days a project usually reaches me as a requirement rather than a ticket — I do the analysis and research, shape the SDLC around it, then run the build with a team of three to five engineers. I still mentor junior developers — a habit I picked up training 50+ students to an 80% placement rate, and never dropped.

Sprint planning, code reviews and agile ceremonies — plus mentoring for junior developers.

Security-first by default

2FA, SSL encryption, AML/KYC compliance and real-time fraud detection baked into every build.

How I Run Projects

From requirement to release — one owned pipeline.

I don't only take tickets. I analyse the requirement, research the approach, design the system and then run the build with the team — the full SDLC, start to finish.

01

Requirement analysis

Stakeholder interviews, scope definition and user stories — written down and agreed before a single line of code exists.

DiscoveryScopeUser stories
02

Research & feasibility

Comparing approaches, APIs and compliance constraints, then documenting the trade-offs so the decision still makes sense six months later.

ResearchTrade-offsCompliance
03

System design

Data model, API contracts and architecture — shaped around the security and uptime the domain actually demands.

Data modelAPI contractArchitecture
04

Build with the team

Sprint planning, task breakdown and code review across a team of three to five engineers, with progress visible to the client every week.

AgileSprint planningCode review
05

QA & UAT

Test passes, client acceptance and every fix tracked to closure — nothing ships on the assumption that it works.

06

Deploy & support

Release, monitoring and the maintenance window that follows — the part most plans quietly forget to budget for.
