CLIENT RESULTS

What partners say

Real feedback from founders, product leaders, and design teams I've worked with.

★★★★★

Our SaaS dashboard was confusing even for power users. Hijam restructured the entire information architecture and introduced smart defaults. Time-to-insight dropped by 41% and churn decreased significantly.

Priya Anand

Co-founder, B2B SaaS • Austin, USA

★★★★★

We needed a scalable design system that engineers would actually enjoy using. Hijam delivered exactly that. Shipping speed increased almost three times and design-dev handoff became much smoother.

Lena Fischer

Engineering Lead, Healthtech • Munich

★★★★★

Our old storefront was beautiful but conversion was suffering. Hijam redesigned the entire user journey with a clear focus on trust and friction removal. Conversion increased by 22% within the first month.

Marcus Webb

Founder, E-commerce Brand • New York

★★★★★

Hijam helped us build a proper design system from the ground up. Before him, our Figma files were messy and inconsistent. Now our entire product team moves much faster with better professionalism.

Sara Kline

Design Director, SaaS • London

★★★★★

Working with Hijam was genuinely refreshing. He doesn’t just deliver beautiful screens — he solves real business problems through thoughtful design. Our user retention improved noticeably after the wallet redesign.

Rohan Mehta

CTO, Fintech • Singapore

★★★★★

Our patient booking flow was causing major drop-offs. Hijam redesigned it with accessibility and clarity in mind. Booking completion increased by 28% and support tickets dropped significantly.

A little about me

From Berlin, Germany to the world's biggest design teams

I've designed customer-facing products at Amazon in Berlin and now at Google, and I bring that discipline to founders and teams who want world-class UX without the agency machinery. Grounded in Bangladesh, working across US and European time zones.

About Hijam Khandakar

Design is how I turn complexity into calm.

I'm a Senior UX Designer and Product Design Consultant based in Berlin, Germany — working with international teams to build digital products people genuinely enjoy using.

My journey

My path into design didn't start in a design school — it started with curiosity about why some products feel effortless and others fight you every step. That question pulled me from Narsingdi to Berlin, and eventually into the design teams of some of the world's most demanding companies.

I sharpened my craft as a Designer at Sure Oak in New York, then stepped into a Senior UX Designer role at Amazon in Berlin, designing customer-facing experiences at massive scale. Today I'm a Senior UX Designer at Google, working while still shipping alongside global teams.

Alongside full-time work, I partner with founders and companies as a freelance consultant — because the problems that excite me most often live inside ambitious startups that need senior design thinking without a senior-sized team.


Mission & philosophy

Clarity over cleverness

The best interface is the one users don't have to think about. I design for understanding first — polish serves the experience, never the other way around.

Evidence, not opinion

Research and data settle debates. I bring the rigor of Big Tech — testing assumptions, measuring outcomes, and letting real users guide direction.

Design that scales

Great products are systems, not screens. I build foundations — components, patterns, documentation — that keep teams fast and consistent long after I'm gone.


What makes me different

A

Big Tech processes

Research-led, systems-driven workflows proven at Google and Amazon — applied at any team size.

B

Personal service

You work directly with me from kickoff to handoff. No account managers, no diluted vision.

C

Cultural understanding

Comfortable across US, European and South Asian contexts — I design for the users you actually serve.

D

Proven results

50+ international projects with measurable lifts in activation, conversion and retention.


Values I work by

Honesty & transparency Reliability Craft & detail Clear communication Ownership Continuous learning

How I work

Five steps from problem to product

01

Discover

Kickoff, stakeholder interviews, user research and competitor analysis. We align on goals, constraints and what success actually looks like.

02

Define

Information architecture, user flows and problem framing. I turn messy requirements into a clear structure everyone can build against.

03

Design

Wireframes to high-fidelity UI and interactive prototypes. Iterative, collaborative and reviewed with you at every meaningful checkpoint.

04

Validate

Usability testing and heuristic evaluation. We test with real users, catch problems early, and iterate before a line of code is wasted.

05

Deliver

Design system, developer handoff package and post-launch QA. Everything documented so your team can ship and scale with confidence.

Common questions

Frequently asked

Most projects run 2–6 weeks depending on scope. Audits and small MVPs land on the shorter end; full feature design, redesigns and design systems on the longer end. I share a clear milestone timeline before we start.

Every package includes structured revision rounds — 2 on Basic, 3 on Premium and Advance, plus post-delivery support. Revisions are focused feedback cycles, not endless tweaking, which keeps quality high and timelines predictable.

Primarily Figma for UI, prototyping and developer handoff, plus Adobe XD and the Adobe Creative Suite when a project calls for it. You get organized, well-named files your engineers will actually enjoy working from.

Yes — I work daily with US and European teams from Berlin. I keep overlapping hours for calls, communicate proactively in async updates, and I'm known for reliable, clear communication regardless of the clock.

Absolutely. I can extend your current system and brand guidelines, or build a fresh, scalable foundation from scratch. Either way, everything stays consistent, documented and easy for your team to maintain.

A short intro to your product, your goals, and any existing assets or research. We cover the rest on the discovery call — I'll come with a plan, and you'll leave knowing exactly what the engagement looks like.

Typically a 50% deposit to book your slot and 50% on delivery, via international payment platforms. Larger engagements can be split into milestone-based payments. Everything is agreed clearly upfront — no surprises.

You get post-delivery support to help your team implement smoothly, plus a design QA session on Premium and Advance. Many clients keep me on a lightweight retainer for ongoing design as their product grows.
