Engagements,
not deliverables.

Four shapes the work usually takes. Each one starts with a real conversation and ends with something measurable.

01

Mobile Development

Native and cross-platform mobile apps with Flutter & Kotlin.

Starts at · MVP from 4–8 weeks

Production Flutter or native Kotlin builds with BLoC / GetX architecture, Firebase, Crashlytics, and CI/CD that removes release fear. From greenfield apps to deep-rescue refactors of crash-prone codebases.

Outcomes I've shipped
  • 01+38% crash-free sessions across iMumz (100K+ users)
  • 02Two enterprise KYC apps shipped at 85% test coverage
  • 03Three marketplace apps with shared module architecture (Bijak)
Best fit for

Startups and enterprise teams who need senior mobile ownership — MVP through long-term ownership.

02

Web Development

Full-stack web applications with Next.js and TypeScript.

Starts at · From 4–6 weeks

Production Next.js builds with TypeScript, server components, and animation systems. From marketing sites and SaaS dashboards to internal tooling that doesn't feel like internal tooling. Backend with Node.js, Express, MongoDB, and Firebase as the data needs.

Outcomes I've shipped
  • 01Fast, SEO-friendly sites with server-side rendering
  • 02Component systems that survive 6+ shipped releases
  • 03Editor / dashboard UX rebuilt around real workflows
Best fit for

Founders and product teams who refuse to ship a default-looking site.

03

UI/UX Design

Beautiful and intuitive user interfaces.

Starts at · Discovery from 1–2 weeks

End-to-end design-to-development pipeline. From wireframes and prototypes in Figma to pixel-perfect implementation. Collaborate with talented designers to deliver visually appealing and user-friendly interfaces.

Outcomes I've shipped
  • 01Wireframe → high-fidelity prototype → shipped product
  • 02Design systems that scale across teams and platforms
  • 03Pixel-perfect implementation with attention to micro-interactions
Best fit for

Teams who want one engineer to own design and engineering for a feature or product.

04

Consulting

Technical consulting and architecture planning.

Starts at · Hourly or retainer

Architecture reviews, hiring scorecards, vendor evaluation, code reviews, or fractional tech-lead support for your next quarter. Lower commitment, higher signal — bring me in for the call your team needs to make right.

Outcomes I've shipped
  • 01Architecture reviews and migration roadmaps
  • 02Fractional technical lead for product teams
  • 03Vendor selection and stack evaluation
Best fit for

CTOs and founders who need senior input without a senior hire.

[ Engagement formats ]

Three ways to work together.

Same craft, different shape. We'll pick the format on the first call.

Sprint2 weeks

Audit, prototype, or surgical fix

Fixed scope
Project6–12 weeks

Greenfield mobile or web build

Milestone-based
RetainerOngoing

Embedded engineering ownership

Monthly
[ Why work with me ]

Senior judgement.
Direct contact.

Most engagements either have great pitching and weak execution, or the other way around. I've made my career on the rare middle.

/ 01

Engineering ownership

I don't write tickets and disappear. Every engagement comes with instrumentation, a measurable bar, and follow-through past the first release.

/ 02

Velocity without theatre

Most teams optimize their process. I optimize the work. Fewer meetings, sharper code reviews, and releases that ship on Friday afternoons.

/ 03

Cross-stack judgment

Mobile-first thinking with web-second pragmatism. I've shipped Flutter to 100K+ and rebuilt Next.js sites from scratch — same toolkit, different surface.

/ 04

Senior, not staff-augmented

You hire me, not an agency layer. Direct contact, direct decisions, no slow-motion handoffs.

[ Section · 08 — How I build ]

Four phases. No theatre.

Most projects fail in the gap between “what we're shipping” and “why we're shipping it.” This is how I close that gap.

01

Discover

Listen first. Map the user, the constraints, the unfair advantage. Define what 'great' looks like before writing a single line.

02

Design

Architect for the second release, not the first. Draft systems, name primitives, and decide what to leave out — that's where the elegance lives.

03

Build

Ship in surgical increments. Tests, instrumentation, and reviews baked in — never bolted on. Velocity comes from confidence, not corner-cutting.

04

Optimize

Measure, profile, refine. Every release should be faster, leaner, and quieter than the last. Performance is a feature.
