Ask HN: Freelancer? Seeking freelancer? (December 2025)
Please lead with either SEEKING WORK or SEEKING FREELANCER, your location, and whether remote work is a possibility.
Please only post if you are looking to hire a freelancer or work as one. Small (2-5 person) agencies are fine, but recruiters, job boards, and so on, are off topic here.

I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.
---
The best live example of my work is Checkbot (https://checkbot.io/), a browser extension that tests websites for SEO/speed/security problems. The entire project is my own work including coding the extension itself, UX/UI design, website design (the homepage is optimised to load in 0.7 seconds, 0.3MB data transferred), marketing, website copy, and website articles on web best practices.

Hi! I’m Olga, an experienced software engineer looking for frontend or fullstack projects.
I have experience building greenfield projects and complex features that “just work,” as well as diving into complex legacy codebases, fixing “unfixable” bugs, and performing major refactoring.
In addition to React/Next.js and Node/Express.js development, I also have experience with cloud-native workflows (Golang + Kubernetes), OpenAI API integration and agentic workflows, native iOS development, and game development. Thanks to my multi-platform experience, I can help you port large products across different platforms.

I am a seasoned (>15 years experience) full-stack staff-level software engineer specializing in the backend, systems architecture, AI, platform engineering, internal tools, prototyping, and data engineering. In addition to strong programming and architectural skills, I'm a force multiplier for any team in either role through the three T's -- teaching, talking, and tooling. I also hold a US patent in the AI space.
In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade.
More recently, I've built a no-code automated form-filler; a no-code web scraper (and an AI for generating such scrapers from a spec and 1-3 example urls from a page); and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patented process that I invented; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).
I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry, which I have given a talk on at a recent functional programming conference.
I have extensive experience working for and running startups, software consulting shops, with some mid-sized company engineering experience as well; these give me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant internal and customer-facing areas of responsibility.
If any of the above seems like a match for you and your organization or project, don't hesitate to reach out. I am available for both short- and long-term contracts.

Who I am:
I'm an experienced (10+ years), versatile Full Stack engineer, specifically have passion in AI-driven application development. I'm seeking an opportunity to contribute to the success of a team while continuing to learn and expand my skills.

Résumé: https://drive.google.com/file/d/1GpChFiIuGqN2U_mF5sMxWjbAPR4...
Email: luchenbrendan @ gmail.com
Technologies: Are listed on my resume and gravitate around fullstack. To get past bad filters, I enumerate TypeScript React Python Scala Elixir Tailwind Linux Node Kotlin Android Docker Git and PostgreSQL, Supabase.
Seeking: Series B -ish, 20-50 headcount-ish, bonus points for work in Health, Education, or Environmental sectors. Hybrid 40% in the Boston metro is ideal, but full remote is fair game, and if you are still reading, have a wonderful day and make a stranger smile.
Statement: Hire me for versatility as a polyglot agnostic builder of stuff, mentorship capacity to strengthen your whole team, bulletproof optimism in a fast-paced and uncertain world, a low-maintenance and well-behaved ego, and the occasional classy dad joke (no, I don't have kids).
