Tech Stack
My Process
A clear, step-by-step approach to delivering great work — from the first call to the final handoff.
Discovery & Understanding
We start with a deep-dive call to understand your goals, audience, and vision. I ask the right questions so nothing gets lost in translation before a single pixel or line of code is written.
Research & Strategy
I research your market, competitors, and users to build a solid foundation. For LinkedIn and pitch decks, this is where the narrative and positioning take shape.
Design & Development
From wireframes to high-fidelity UI or from design to working product — I execute with precision. Every screen, interaction, and component is built with the end user in mind.
Review & Refinement
You review, I refine. Feedback rounds keep the work aligned with your vision until it feels exactly right. No guesswork, no surprises.
Delivery & Support
Final files, live product, or optimized profile — everything handed off clean and ready to use. I stay available post-delivery to make sure everything runs smoothly.
What Colleagues Say
Mrinal has always had good eye for design and incessantly worked towards crafting Tiomands platform. He had designed the user journey meticulously and never refrained from going out of the way to make others team use and share their view for the platform before launch.

Mrinal and I work for the same organisation but belong to different product teams. Still, we hang out in the office and discuss our daily priorities. Sometimes, I even ask for his feedback. He is easy to approach and that constructs one good point. Secondly, he is very open to sharing his knowledge with the team. Lately, he has helped to sort a few AI tools and Spline (A tool for 3D interaction). Beyond this, he is very consistent in his learning approach. So overall he is a very passionate contributor.

FAQs
I offer four core services: UX / UI / Product Design (0→1, research to design systems), Product Engineering (design + development + deployment end to end), LinkedIn Growth Service (profile optimization, content strategy, and recruiter outreach), and Research & Pitch Deck Design (investor-ready decks with deep market research). Whether you need a full product built, ongoing design/dev support, or a stronger LinkedIn presence — I cover it.
Yes. On Flat Fee projects, I handle the full stack — UX/UI design and product development — so you get a live, working product, not just mockups. For Monthly clients, I offer unlimited design or dev requests, plus LinkedIn optimization and pitch deck design on demand. I merge design, engineering, and AI to ship production-grade products fast.
Flat Fee starts from $999/project — best for startups needing a complete product designed and built from scratch, with up to 3 major revisions, source files, and 2 weeks of post-delivery support. Monthly is $2,000/month — ideal for ongoing design, development, or LinkedIn growth, with unlimited requests, a dedicated project manager, and a monthly strategy call.
Timelines depend on scope. A focused 0→1 product (design + development) typically takes 4–8 weeks. LinkedIn profile optimization can be done in 1–2 weeks. Pitch decks usually take 1–3 weeks depending on research depth. Monthly engagements run on a rolling basis with continuous delivery — we align on priorities in our monthly strategy call.
I follow a 5-step process: Discovery & Understanding (deep-dive call to align on goals), Research & Strategy (market, competitors, and narrative), Design & Development (wireframes to high-fidelity UI or working product), Review & Refinement (feedback rounds until it feels right), and Delivery & Support (clean handoff with post-delivery availability). No guesswork, no surprises.
Absolutely. Scroll to the Engineered with AI section to see products I've built — BharatX (AI finance search), PayAgent by LCX (agent-to-agent payments), Quantiva (AI market intelligence model, live on Ollama), Calmora (mental wellness), and more. Quantiva has a full case study at /projects/quantiva covering LLM fine-tuning, deployment, and benchmarking.
Yes. Flat Fee projects include 2 weeks of post-delivery support to make sure everything runs smoothly. Monthly subscribers get continuous support with a dedicated project manager and regular strategy calls. I'm available to fix bugs, iterate on features, or help with LinkedIn content — depending on your plan.
Flat Fee includes up to 3 major revisions — enough to refine the product until it matches your vision. Monthly plans include unlimited design or dev requests, so you can iterate as much as you need. I keep feedback rounds structured so we stay aligned without endless back-and-forth.
