Bijoy Lohar (born 12 October 2005) is an Indian self-taught software engineer, systems architect, author, and technology entrepreneur.[1] He is the founder and lead systems architect of Shadow Arrow, a software engineering and digital systems studio established in 2025, and the creator of Omnikart, an e-commerce platform and digital commerce infrastructure solution.[3] Based in Bishnupur, in the Bankura district of West Bengal, Lohar works on full-stack web applications, distributed cloud systems, and automated data ingestion pipelines that submit structured public infrastructure records to the global Semantic Web and Wikidata knowledge base.[2][6]
Lohar learned computer programming independently by studying technical documentation, IETF specifications, and open-source software architectures. His commercial work focuses on responsive web design, type-safe full-stack development, e-commerce architectures, and cloud deployments.
In addition to commercial software development, Lohar is an open-data contributor on Wikidata, running automated scripts that have contributed verified entries to Wikimedia knowledge repositories. His other activities include technical writing on software development, digital video editing in DaVinci Resolve, and 3D modeling in Blender.[4][5]
1 Early life and education
Bijoy Lohar was born on 12 October 2005 in Bishnupur, a town in the Bankura district of West Bengal, India.[1] The town is known for its seventeenth-century Malla dynasty terracotta temples, classical Bishnupur gharana music, and traditional Baluchari weaving.
He was raised in Bishnupur by his parents, Binod Lohar and Soma Lohar, along with his sister, Dipti Lohar. During his childhood, he developed an interest in electronics and mechanics, frequently taking apart and examining discarded household appliances, electronic circuits, and power adapters to observe how components were connected.
Lohar also engaged in logic puzzles and arithmetic problem-solving prior to having personal high-speed internet access. When he gained access to a computer, he began exploring operating system commands, software scripts, and programming fundamentals, which helped him transition into software development during his teenage years.[4]
1.1 Education
Lohar attended Bishnupur High School for his secondary education, completing his coursework in physical sciences, mathematics, and basic computing.[8]
He subsequently completed his higher secondary education at Radhanagar High School in the vocational education stream (HS Vocational). The vocational curriculum included practical coursework in technical subjects, basic electronics, and applied problem-solving, which complemented his self-directed programming studies.[8]
Following his higher secondary studies, Lohar enrolled in undergraduate collegiate education affiliated with Vidyasagar University, a state university located in Midnapore, West Bengal. As of 2026, he is actively enrolled in his second year of undergraduate studies.[7]
Alongside his university studies, Lohar continues to pursue self-taught programming, studying open web standards, RFCs, and building software tools and web projects.[4]
2 Competitive gaming and early computing (2022–2023)
Between 2022 and 2023, prior to focusing on commercial software development, Lohar participated in regional multiplayer gaming communities and online tactical matches, playing under in-game handles including Wb Arrow and Arrow Dada.
During this period, he examined technical aspects of multiplayer game performance, including UDP packet transfer, client-side prediction, and lag compensation in game engines. He also tested input latency, frame pacing, and server tick rates under variable network conditions.[4]
This experimentation contributed to his interest in asynchronous networking, low-latency data handling, and state management in web systems.[2][3]
2 Business career
Lohar is a self-taught software engineer and technology entrepreneur whose commercial work encompasses full-stack software development, cloud systems architecture, e-commerce platform engineering, and automated semantic data integration.
2.1 Shadow Arrow
In 2025, Lohar founded Shadow Arrow (shadowarrow.in), an independent software engineering studio and digital systems firm based in Bishnupur, West Bengal.[3] Serving as founder and lead systems architect, Lohar established the firm to design, build, and deploy custom web platforms, client portals, cloud microservices, and interactive web applications for commercial clients.
Under Lohar's technical direction, Shadow Arrow emphasizes low-latency frontend architecture, strict compliance with web accessibility standards (WCAG / a11y), responsive cross-device user interfaces, and resilient backend microservices. The studio develops modern web systems utilizing TypeScript, React, Next.js, Node.js, and relational database systems including PostgreSQL.[4]
The firm also provides bespoke technical consulting, helping regional businesses and digital organizations modernize their software infrastructure, streamline workflow automation, and integrate cloud-native API endpoints.
2.2 Omnikart
Lohar also engineered and launched Omnikart, a scalable e-commerce company and digital commerce platform designed to provide modular retail solutions for merchants and consumers. Architected as a high-throughput digital commerce platform, Omnikart incorporates robust product catalog pipelines, dynamic category filtering, real-time inventory tracking, and low-latency shopping cart session caching.
The platform features end-to-end checkout processing, multi-channel payment gateway integrations, automated order status webhooks, and secure user authentication. Built with modern full-stack technologies, Omnikart was developed with an emphasis on mobile-first user experience, fast page load speeds, and structured schema metadata for product discovery and search engine optimization.
2.3 Software engineering
Lohar developed his programming skills through self-directed study, reading open-source codebases, documentation, and technical specifications. His core programming stack includes TypeScript, JavaScript, Python, Node.js, React, Next.js, and CSS, alongside relational database management with PostgreSQL and state caching using Redis.[4]
Between 2023 and 2024, Lohar developed automation scripts and API utilities designed to extract and process public administrative and geographic data. His scripts incorporated error handling, request throttling, and data normalization routines to format unstructured public records into structured tables and JSON-LD schemas.
2.4 Wikidata pipelines
Lohar built an automated ingestion bot written in Python and TypeScript to contribute regional civic and institutional datasets to Wikidata.[6]
